Available 18-tonne truck body types

Box and curtainside are the usual choices. Refrigerated work and tail-lift handling require the right completed vehicle, rather than a generic truck specification.

Box body: enclosed freight space.

A box truck has a fixed enclosed goods body. It suits packaged retail stock, furniture, appliances, cartons, exhibition equipment and compatible pallets where side forklift access is unnecessary. Rear loading is the usual starting point; side doors are specification-dependent.

Rigid walls give an enclosed working space, but they are not automatically rated to restrain every load. Check the door aperture, floor, securing points, water protection needed by the goods and the unloading method. A box body does not imply a tail lift.

Curtainsider: access along the side.

A curtainside body can allow a forklift to reach suitable goods through the side as well as use the rear. This can help with long pallets, awkward crates, machinery and a delivery sequence that would be difficult in a rear-loading box.

Posts, rails, roof height and the actual clear opening still matter. The curtain is weather protection, not a universal restraint system. Opening a side does not supply a forklift, create a crane or make a long pallet suitable for a rear tail lift.

Refrigerated or temperature-controlled bodies need their own check.

A purpose-built refrigerated truck has its insulation incorporated into the body construction. Its internal load space can be comparable with a similarly sized dry box, so refrigeration does not automatically mean a smaller cargo area. Refrigeration machinery, insulation, the tail lift and associated equipment add vehicle weight and can reduce the freight payload.

The refrigerated retail-delivery trucks we arrange are normally fitted with tail lifts. Confirm the actual platform and handling equipment for your load. Send the packaged dimensions, weight, temperature range, loading temperature and monitoring needs. Internal evaporators, bulkheads and required airflow still need checking, particularly for multi-temperature work. Cooling equipment does not replace correct preconditioning, packaging or door management.

The chassis badge does not define the cargo body.

A truck is often supplied as a chassis cab, then completed by a body builder. Wheelbase, chassis specification, body length, wall thickness, roof height, rear doors, floor and handling equipment can all differ between vehicles carrying the same 18-tonne description.

The body is part of the vehicle weight. A long, tall box may offer more volume while leaving less freight capacity. A light body may retain more payload, but only the actual completed vehicle and its permitted weights establish what can be accepted.

Tail lift and pallet truck need the right specification.

Ask for a tail lift when suitable freight must move between the truck floor and ground. Refrigerated retail vehicles normally have one; do not assume the same for every dry box or curtainsider. Specify whether a pallet truck is needed too. The installed platform size, rating, load-centre chart, access and safe operating surface must match the individual load.

Box and curtainside are the main body choices for this guide, with refrigerated work assessed separately. Flatbed and specialist HIAB or truck-mounted forklift arrangements need a separate specification. A crane, forklift, mounting frame and stabilisers add vehicle weight and can change dimensions, axle loading and usable freight capacity. Describe the task before selecting the truck.

Specify access and equipment.

Cooling does not automatically remove interior space. Purpose-built refrigerated construction can preserve comparable internal dimensions while its equipment affects available payload.

Confirm doors, airflow and temperature requirements alongside the tail lift and individual load.

Three comparable two-axle rigid body examples: rear-access box, open curtainside with a forklift, and refrigerated body with cooling equipment and a tail lift. Cargo body lengths match; refrigeration equipment can reduce payload.
Actual body dimensions, doors, equipment and payload must be checked.

18-tonne truck dimensions and pallet capacity

Start with the booking guide, then check the completed vehicle, loading aperture and the finished goods.

Use 7.5 × 2.4 × 2.5 m for initial planning.

Our existing category guide uses 750 × 240 × 250 cm of internal load space and up to 9,000 kg total consignment weight. The rectangular calculation is 45 m³. These figures are a starting point, not guaranteed clearances or certified usable volume.

Plan for up to fourteen suitable UK pallets at 120 × 100 cm, or up to eighteen Euro pallets at 120 × 80 cm in an appropriate body and layout. Pallet count, loaded size, individual weight and unloading method must all work together.

Body builders can change every useful measurement.

An 18-tonne rigid is often completed from a chassis cab. Wheelbase, body length, wall construction, roof height, door frames, shutters, lift and floor fittings vary. A shorter-bodied truck may carry less bulky freight while retaining more payload.

A 7.5 m floor does not guarantee that a 7.5 m long crate can pass through the opening and be secured. Measure the packaged item, fork entry and loading path. Internal height is different from the vehicle height needed at a bridge or loading-bay canopy.

UK pallets: two orientations, fourteen positions.

Seven rows of two UK bases, with 100 cm along the truck and 120 cm across, occupy 700 × 240 cm. That leaves 50 cm nominal length against the 7.5 m guide, but zero nominal width margin. The actual clear body must support the finished loaded width.

A mixed alternative uses six bases at 120 cm along in one 100 cm-wide lane, and eight rotated bases at 100 cm along in one 120 cm-wide lane. That needs 800 × 220 cm, so it belongs to a suitable 8 m body, not the 7.5 m guide.

Euro pallets: eighteen positions need the right width.

Nine rows of two Euro bases, with 80 cm along and 120 cm across, occupy 720 × 240 cm. This leaves 30 cm nominal length against the guide and zero nominal width margin. Loaded overhang, airflow and restraint can reduce the count.

In a narrower example, six bases at 120 cm along in an 80 cm-wide lane and nine rotated at 80 cm along in a 120 cm-wide lane provide fifteen positions within 720 × 200 cm. This illustrates why “Euro” does not guarantee eighteen on every truck.

UK loading: fourteen nominal positions.

The 7.5 m example occupies 700 × 240 cm. It requires the complete clear width before any loaded overhang or working clearance.

The mixed fourteen-base alternative uses an 8 m body. It does not fit within the 7.5 m guide. These are geometry examples, not loading orders.

Euro loading: width changes the count.

Eighteen bases occupy 720 × 240 cm in the guide example, with no nominal width margin. The narrower mixed example shows fifteen.

Rotated bases must suit the forks and transfer method. Confirm the finished pallet footprint, weight, support, restraint and actual body.

Two numbered pallet-base floor plans. 14 UK bases occupy 7,000 × 2,400 mm in a 7,500 mm body. An alternative 8,000 mm layout has six bases in one lane and eight in another, occupying 2,200 mm width.
Pallet-base geometry only. Loaded overhang, doors, restraint clearance, weight, axle distribution and handling must be checked.
Two numbered pallet-base floor plans. 18 Euro bases in a 7,500 × 2,400 mm floor, with 300 mm length remaining; 15 mixed-orientation bases in a 7,500 × 2,200 mm narrower floor.
Illustrative base layouts. Actual loaded size, clearances, weight, axle distribution and loading method decide capacity.

Floor positions and tonnes are separate limits.

Fourteen loaded UK pallets at 600 kg total 8,400 kg. Fourteen at 650 kg total 9,100 kg and exceed the 9,000 kg guide. Eighteen loaded Euro pallets at 500 kg use the entire guide; eighteen at 550 kg total 9,900 kg and exceed it. Include bases, packaging and supports.

An 8 m × 2.4 m floor can mathematically hold twenty Euro bases in ten rows of two, with zero margin in both directions. That is not our standard booking allowance. Do not upgrade the count from a drawing alone.

All layouts are floor geometry examples, not axle-approved loading plans. Fork entry, rotated pallet compatibility, loaded stability, unloading order, floor strength, restraint and actual clearance require assessment. Double stacking needs suitable goods and equipment; it is not included in these counts.

03 / Where a larger rigid earns its place

What an 18-tonne truck is used for

More freight capacity and useful body space, with a rigid layout that can suit some sites an artic cannot reach.

18 tonnes is the gross vehicle category.

An 18-tonne truck is commonly a two-axle rigid with a maximum authorised mass of 18,000 kg. The cab and freight body share one chassis. That gross mass includes the completed truck, people, fuel, equipment and freight. It is not an 18-tonne cargo allowance.

Mercedes-Benz Actros or Axor, DAF, Volvo, MAN, Renault and other chassis families can be completed differently. The badge alone does not establish payload, doors, floor strength or tail-lift capability.

Useful for heavy pallets and commercial distribution.

Suitable work includes packaged machinery, engineering components, retail replenishment, printing, store fittings, furniture, building products and event equipment. Dense goods can justify the payload even with few pallets. Light goods can justify the body before its weight allowance is used.

A consignment that exceeds the 7.5-tonne guide may fit one suitable 18-tonner, avoiding several smaller journeys. Regular haulage, supplier collections, RDC-to-store movements and agreed multi-drop work can be as relevant as an urgent dedicated delivery.

The benefits are practical.

A rigid vehicle can simplify some approaches and manoeuvres compared with an articulated combination, while adding substantial freight capacity over a smaller truck. Curtainside access can suit long loads; a suitable tail lift can support agreed ground-level unloading.

A single vehicle can keep compatible goods together and reduce duplicated positioning, loading and administration. Those benefits depend on the complete job rather than the gross weight badge.

The disadvantages need planning.

More length, height, weight and turning space can exclude loading bays, narrow streets or weak surfaces. A larger truck can add operating cost without improving a small delivery. Tail-lift and specialist equipment still have their own limits.

Drivers’ hours, working time, tachographs, suitable rest stops and site delays affect the timetable. A bigger body does not make unloading quicker, remove a queue or supply a forklift at the destination.

Choose the completed vehicle.

The same chassis class can carry a box, curtainside, refrigerated body or a separately specified specialist configuration. Body weight, axle positions, door size and handling equipment determine useful capability.

Tell us the freight and receiving-site requirements first. We can then assess the body, handling method, route and duty plan together.

26-tonne rigid8.0 × 2.5 × 2.6 m / 52 m³Up to 15,000 kgUp to 16 UK; Euro count requires body/layout confirmationMore weight or floor space than the 18t guide supports

Use the 7.5-tonner when it meets the whole job.

Eight compatible 200 kg UK pallets total 1,600 kg. If they fit a suitable body and the unloading equipment works, an 18-tonner may add no useful benefit. The smaller rigid can also be the practical upper size for a particular shop, street or bay.

Conversely, a 4,000 kg consignment exceeds our 7.5-tonne guide even if it occupies only four pallets. Assess a suitable 18-tonner rather than relying on spare space as permission to add weight.

Use the 26-tonner for a real capacity need.

A 12,000 kg load exceeds our 18-tonne freight guide. A suitable 26-tonne body may provide the extra capacity, provided the axles, floor, handling and route work. Fifteen or sixteen UK pallets can also need a different floor arrangement.

More axles and a higher gross rating do not guarantee more usable floor length, a higher-rated lift or entry into the same loading bay. Confirm the specific body and site rather than making a decision from the label.

Individual-item handling can decide the category.

One 1,800 kg machine needs a compatible floor and loading/unloading system, even when its weight is below the total payload guide. A larger truck with an unsuitable lift does not solve that problem.

Compare like-for-like quotes: body, equipment, staff, slot, waiting allowance, full mileage and rest plan. Avoid both an under-capacity booking and a larger vehicle that offers no useful advantage.

Choose on the limiting requirement.

A smaller vehicle can be enough for light freight but fail a heavy shipment. A bigger vehicle can carry the weight yet fail the bay.

Compare the complete body and handling specification, then check the route and duty plan.

05 / Legal access and physical fit

7.5-tonne signs, city access and loading bays

An access exemption can permit a qualifying delivery. It cannot make a bigger truck fit a smaller bay.

Read the restriction and its exemption together.

A lorry-symbol restriction above a stated maximum gross weight is different from a structural weight restriction. Some environmental restrictions have a supplementary plate such as “Except for access” or an exemption for loading and unloading. A qualifying collection or delivery within the restricted area may therefore be permitted in an 18-tonner.

This is not a universal exception on every 7.5-tonne sign. Check the exact wording, times, local traffic order and route. Access must be for the permitted purpose, not a shortcut through the area. Where the exemption is unclear, confirm it with the responsible authority before planning the movement.

Maximum gross weight is not the weight of the goods.

A goods-vehicle restriction based on maximum gross weight can apply to an 18-tonner even when it is empty or carrying only one light pallet. Do not assume it becomes a 7.5-tonne vehicle because the actual load is small.

A structural bridge or road weight limit protects the structure. It can be based on plated maximum gross weight, even when the truck is lightly loaded. Read the exact sign and order; an empty-vehicle exemption only applies where it is actually provided. Do not infer an access exemption, ignore it for a delivery, or substitute a freight-only calculation. Axle restrictions, weak surfaces and other signed limits need separate checks.

Permission to enter and room to unload are different.

An 18-tonner may have a legitimate access exemption yet still fail a tight turn, canopy, ramp or loading bay. A site may only accept a Luton or suitable 7.5-tonner. The access plate does not override height, width, length, bridge, pedestrian, permit or timed-entry restrictions.

Ask the site for the approved entrance and maximum outside dimensions, gross weight, bay depth, ramp limits, turning area and unloading method. Send photographs of the complete sign and its plates. A postcode or “HGV access” note is not enough for a restricted city delivery.

The exemption belongs to the restriction.

A qualifying access or loading exemption can permit delivery within an environmental restriction. It is not a blanket exemption on all 7.5-tonne signs.

Confirm the local order and all other restrictions. Structural weight limits and physical clearance are separate decisions.

An access exemption does not cancel separate bridge, structural, height, width or private-site restrictions.

Residential delivery also needs parking, pedestrians, trees, overhead services and the safe unloading point considered. A tail lift does not automatically include room-of-choice delivery, stairs or two-person handling. If access requires a smaller final vehicle, assess splitting, transhipment and equipment before confirming the service.

06 / Payload, body weight and axle position

18-tonne truck payload explained

The badge, the catalogue and the loaded working vehicle can describe different things. The actual allocation must support the weight and its distribution.

Why our initial guide is 9 tonnes.

We use up to 9,000 kg as a practical category starting point across varying completed bodies. Some vehicles can legally carry more and others less. It is not a promise that every box, curtainsider or refrigerated truck has identical working capacity.

Advertised chassis payload may be the mass available for the body and freight together. After a third party fits the goods body, tail lift and other equipment, the amount available for the consignment is lower. Compare completed working specifications on the same basis.

Every kilogram needs the right place in the calculation.

Bodywork, refrigeration, fuel, driver and any crew, pallet truck, spare equipment and fixed fittings contribute to laden vehicle weight. Pallets, wrapping, crates and supports contribute to the shipment. Do not count the same allowance twice when reading an already completed payload specification.

For a purely hypothetical truck, a measured ready-to-load weight of 9,000 kg would leave 9,000 kg below an 18,000 kg gross limit. At 9,500 kg, only 8,500 kg would remain. Neither calculation establishes axle compliance or makes those example weights typical.

Separate capacity checks before loading
LimitWhat it controls
Company freight guideThe initial category allowance, including shipment packaging and pallets
Actual gross weightThe completed vehicle’s total legal laden mass
Individual axle limitsHow the laden weight is distributed between the axles
Body floor and point loadsConcentrated pressure from feet, skids, wheels or dense goods
Handling equipmentThe forklift, tail lift or pallet truck at the relevant position and load centre
Goods support and restraintWhether the item can be held safely without damaging it or the vehicle

Being below the gross limit does not prove both axles are legal.

Putting a dense item near the tail changes the axle reactions. A load behind the rear axle can add more than its own weight to that axle while reducing the front axle load. Check distribution rather than adding pallet weights alone.

Multiple deliveries can alter the balance as freight is removed. A layout suitable at collection may need reassessment after an earlier drop. Dense machinery, liquids and concentrated supports need a specific loading plan.

A tail lift’s own mass reduces what remains available within the gross weight, but there is no universal 100 kg or 150 kg deduction for every 18-tonne installation. Ratings, platform types and structures differ. Refrigeration and heavier bodies can make a further difference. Confirm the working freight allowance for the truck being supplied.

A conservative company guide does not change the legal plate. Keeping load within all applicable limits also supports braking, steering, tyre and suspension performance. Do not treat an assumed safety margin as permission to exceed either a company booking limit or a legal one.

A gross calculation does not approve the axles.

The arithmetic example starts with a hypothetical ready-to-load mass. The actual truck must be measured or specified on a reliable completed basis.

Dense loads and successive deliveries can change the axle balance. Confirm the loading plan, floor and equipment.

Hypothetical 18,000 kg maximum mass less a 9,000 kg ready-to-load truck leaves 9,000 kg freight. A separate cutaway puts dense freight near the rear and highlights the rear axle. Gross, axle, floor and equipment limits remain separate.
Hypothetical calculation. Actual ready-to-load weight and plated limits must be checked.
07 / The individual item and both ends of the job

Tail lifts, pump trucks and long pallets

Tell us how each item will leave the truck. “Tail lift required” starts the assessment; it does not finish it.

Ground-level unloading by agreement.

A compatible tail lift moves suitable freight between truck floor and ground. Its capacity is separate from the 9,000 kg freight guide. Platform depth, width, permissible load centre, support and the transfer route matter as much as the headline rating.

Count everything carried on the platform: the loaded pallet, the pallet truck and any operator permitted by the manufacturer’s instructions. A lift labelled 1,000 kg is not proof that every 1,000 kg pallet can use it at every position.

Check pallet-truck compatibility.

Pallet fork entry, bottom boards, fork length, under-clearance, stability and individual loaded weight all matter. Standard equipment may not engage an unusual stillage, long pallet, damaged base or low-clearance machine.

For an individual loaded pallet weighing 800 kg or more that requires pallet-truck handling, request an electric pump truck. This is Synergix’s booking rule, not a universal legal threshold or a guarantee that the lift and route are suitable. Lower weights can also require powered handling.

Freight capacity is not tail-lift capacity.

In a hypothetical example, a 900 kg pallet plus a 100 kg pallet truck totals 1,000 kg before any permitted operator mass is included. That leaves no capacity margin on a hypothetical 1,000 kg platform. The applicable load chart and working arrangement still need checking.

Fourteen UK pallet spaces or eighteen Euro positions do not mean pallets of any individual weight can be lowered. Give us both total shipment weight and the heaviest single item. The transport and handling checks must pass separately.

A long pallet can fit the body and still fail at the lift.

A 3 m pallet may sit inside a 7.5 m body but still be unsuitable for rear tail-lift transfer. It needs supported platform space, correct pallet-truck engagement, an acceptable load centre and a workable route through the opening.

Do not assume turning it diagonally solves the problem. Packaging rigidity, support positions and available manoeuvring room matter. Where rear transfer cannot be done safely, a different agreed method is needed.

Curtainside forklift loading can solve a different problem.

A suitable side-opening body may let a forklift place a long or awkward consignment through the side. The forklift must have capacity at the actual load centre, suitable forks or approved support, and clear working space.

Confirm that suitable unloading equipment also exists at delivery. A forklift at collection does not equip the destination. Side loading is not self-unloading, and a curtainsider does not automatically carry a truck-mounted forklift.

Explain any loading dock or dock leveller too. Truck floor height, lift stowage, dock approach, bridging and site procedures must be compatible. Do not assume a tuckaway, column or cantilever lift suits every dock because the truck has the right gross rating.

Ground-level unloading is normally limited to the agreed safe point. A standard pallet truck cannot cross every driveway or threshold. Grass, gravel, soft ground, broken surfaces, steep slopes and tight passages can require another plan. Keep lift operating space clear of people and traffic.

Assess the individual item.

A 9,000 kg freight allowance does not establish the tail-lift rating. Add the loaded pallet, handling equipment and any permitted person on the platform.

For long or heavy freight, confirm support, load centre, doors and the handling method at both sites.

Confirm platform size, support, load centre, door opening, lift rating and handling method.
08 / Clearance, ground and load security

Can the truck reach, unload and leave?

Useful payload is only valuable if the route and premises can accept the completed vehicle and its handling method.

Plan the route, the stop and the exit.

Check height barriers, low bridges, gates, tight corners, road restrictions, turning areas and the space needed to open the body or deploy a platform. Body width excluding mirrors is not the whole clearance requirement.

Rear overhang can swing towards nearby vehicles or structures as the front turns. Ramps and abrupt ground transitions can reduce underbody or tail clearance. Parked cars can make an otherwise usable street unsuitable on the day.

Load to unload safely.

The sequence should allow the driver and site team to release restraints and handle the next item without an unstable remaining load. Avoid trapping heavy goods behind fragile consignments or removing support needed by another item.

Share the freight description, centre-of-gravity concerns, packaging and handling instructions before allocation. Pallet wrap holds goods together; it does not automatically secure the pallet to the vehicle. A curtain should not be relied upon as generic load restraint.

Check the shopping-centre loading bay before choosing the truck.

City-centre shops, shopping centres and large buildings can have covered loading bays, height barriers, ramps and strict vehicle limits. Some sites accept suitable 7.5-tonne trucks; others require a Luton or another smaller vehicle. An 18-tonner may therefore be excluded even where a delivery-access exemption applies. Synergix regularly encounters bookings where the goods fit but the requested vehicle cannot enter the bay.

Ask the receiving site for its maximum permitted vehicle height, length, width and gross weight, the delivery entrance, ramp and turning restrictions, and the permitted unloading method. We must check the completed truck’s actual outside dimensions, including roof equipment, against those limits. “18 tonnes allowed” does not guarantee that every 18-tonne box will fit.

Send the bay instructions, booking slot, contact and any clearance information before allocation. If a smaller vehicle is required but the load exceeds its safe payload, the plan may need multiple agreed trips or a suitable transfer arrangement. Do not rely on arrival-day improvisation.

Loading arrangements are part of the booking.

A safe area needs firm suitable ground, clear people and vehicle movements, and agreed responsibility for the task. Confirm who supplies and operates the equipment at collection and delivery.

Where reversing is unavoidable, follow the site’s assessed arrangements. A person waving the truck back without an agreed safe system does not remove the risk. Tell us about restricted visibility, public footways and busy shared yards.

Securing methods depend on the goods, vehicle and equipment. Suitable straps, blocking, anti-slip materials, load-rated structures and attachment points may be relevant, but a generic diagram cannot prescribe a complete securing specification. Goods must remain stable when individual restraints are removed at delivery.

Two-person handling, building entry, special packaging, fragile goods and high-value equipment need advance agreement. Insurance and claims arrangements should be discussed where the goods warrant it; do not assume a particular cover limit from the truck category.

A useful body still needs a usable route.

Check the approach, loading position and exit with the receiving site before vehicle allocation.

Send real entrance instructions and measurements. Avoid relying on a broad truck category to approve a covered bay.

An overhead commercial site separates approach, unloading position and exit. The parked truck has rear doors open and a deployed lift with a hatched working area. Parked cars sit outside the route. An inset compares the truck exterior and bay opening.
A site accepting deliveries does not mean every truck fits. Obtain the actual bay and access details.
09 / Time is a vehicle-selection factor

18-tonne truck drivers’ hours

The freight can fit and the route can be clear, yet the proposed timetable may still need a different arrangement.

A normal commercial 18-tonne goods delivery is generally subject to assimilated drivers’ hours rules and tachograph recording. Specific exemptions exist, but an urgent customer deadline is not itself an exemption. The journey to collection and relevant onward driving are part of the plan, including empty positioning for the job.

Core driving and rest limits for a standard single-driver operation in scope. Exceptions and international arrangements require their own assessment.
RequirementGeneral starting rule
Daily drivingUp to 9 hours, extendable to 10 hours twice in a week.
Weekly drivingUp to 56 hours, with no more than 90 hours across any two consecutive weeks.
Driving breakAt least 45 minutes by 4 hours 30 minutes of accumulated driving. A split can be at least 15 minutes followed by at least 30 minutes, in that order.
Daily restNormally at least 11 hours, with permitted reductions to 9 hours no more than three times between weekly rests. Daily rest must fit within the applicable 24-hour period measured from the end of the previous daily or weekly rest.
Weekly restNormally 45 hours. A permitted reduced weekly rest is at least 24 hours; compensation must be arranged by the end of the third following week. Weekly rest must start by the end of six 24-hour periods after the previous weekly rest. The required pattern and any international exceptions need assessment.

A driving allowance is not a delivery window.

Four hours of driving does not imply arrival four hours after enquiry. Positioning, checks, loading, traffic, safe stopping, breaks and unloading need room in the schedule. A driver may already have used part of the available allowance before this job.

A delivery slot near the end of the day needs particular care. A long queue can remove the room needed to unload and reach suitable rest accommodation, even if the remaining road mileage appears short.

Stopping is not automatically a break.

Unloading, paperwork, checks and other duties are work. A driver supervising a transfer is not taking a driving break simply because the vehicle is parked.

Where a planned stop can legitimately serve as a break, the driver must be free of the relevant duties. Loading staff, a queue, a ferry or a charging stop should not be counted as a qualifying break without checking the actual arrangement.

Illustration: 4 hours 30 minutes of driving is not a 4-hour-30-minute working day.

A driver might start with checks and loading, then drive for two hours, unload, and drive for another two and a half hours. The intervening handling does not reset accumulated driving. A qualifying driving break is then required before further driving, and working-time breaks may already have become due.

This is an explanation of the separate clocks, not an approved duty roster. Previous work, rest, night work and the full onward plan still need assessment.

Handling does not reset driving.

The driver can work while the truck is parked. Loading and supervising unloading are not automatically driving breaks.

Both clocks and the rest plan must remain compliant. A deadline cannot create unused driving allowance.

Two activity timelines share checks, drive, load, drive, unload and break blocks. Only driving contributes to the driving clock; checks, driving, loading and unloading contribute to working time. Loading does not reset accumulated driving. A qualifying 45-minute break is due by 4 hours 30 minutes driving.
Simplified explanation for normal in-scope operation. Previous duties and all applicable limits still count.

Check the current GOV.UK drivers’ hours summary and the detailed driving, break and rest guidance. These rules affect the service plan; they cannot be removed by paying for a faster delivery.

10 / Driving, work, availability and rest

Working time and tachographs

Loading time, waiting and customer appointments can change the available day as much as the road distance does.

Working time covers more than driving.

For mobile workers within the road transport working-time rules, work includes driving, checks, loading, unloading, maintenance and relevant administration. Known, qualifying periods of availability are treated separately; an uncertain queue is not automatically availability or rest.

The tachograph records the activity.

It records driving, other work, breaks and rest, periods of availability, speed and distance. Drivers must use the appropriate mode and entries, and operators must monitor compliance. A tachograph is a working record, not simply a speed recorder.

Working-time rules are separate from driving limits. General rules for in-scope mobile workers.
MeasureGeneral rule
Average working week48 hours, normally over a 17-week reference period. A qualifying agreement can extend the reference period to 26 weeks.
Any single weekUp to 60 hours, provided the required average is respected.
Work without a breakNo more than 6 consecutive hours.
Total working-time breaksAt least 30 minutes for 6 to 9 hours of work, or 45 minutes above 9 hours. Break portions must be at least 15 minutes.
Night workFor goods transport, work during 00:00 to 04:00 triggers a general 10-hour working limit in 24 hours. A valid collective or workforce agreement can vary the night-work limit.
Opt-outThere is no individual opt-out from the 48-hour average under these road transport rules.

A qualifying break can satisfy more than one requirement, but the operator must assess the complete duty. A nine-hour driving allowance does not automatically authorise nine hours of driving plus unlimited loading. A reduced rest does not remove working-time controls.

For customers, the practical response is to share the real loading time and access slot. A “quick collection” that regularly takes two hours should be booked on that basis. Keeping the driver informed helps us assess changes before a deadline becomes unworkable.

See DVSA working-time guidance and tachograph requirements.

11 / Accommodation and the full assignment

Day cabs, sleepers and overnight delivery cost

A truck with enough payload may still need more time, accommodation and a different duty plan than a smaller van.

A day cab is not overnight accommodation.

18-tonne trucks may have day cabs or sleeper cabs. The selected specification depends on the assignment. Do not assume that the selected truck has a sleeper berth or that a driver can sleep on the seats.

Where an overnight stop is needed, suitable accommodation and parking may need arranging. A hotel can add room cost, travel between the truck and hotel, secure parking and a later start after the required rest. These details affect the quote.

Rest must be possible in the real arrangement.

Daily rest in a vehicle is permitted only under the applicable conditions, including suitable sleeping facilities and a stationary vehicle. Regular weekly rest cannot be taken in the vehicle. A sleeper does not make every overnight arrangement lawful.

Accommodation should let the driver obtain the required uninterrupted rest. A delivery site expecting the driver to move the truck repeatedly overnight can undermine that plan.

A long outward trip also needs an onward plan.

A truck does not disappear at the delivery point. Consider return travel, another collection, parking and rest. Even when an outward delivery can be completed in one day, the whole assignment may require an overnight stop.

Depending on the job, we can assess a different schedule, suitable driver arrangements or another transport plan. A second person in the cab is not automatically a qualified second driver, and two-person unloading is a different service from multi-manning.

Tell us if the load must arrive overnight, the site closes at a fixed time or collection cannot begin until late afternoon. Agree accommodation and overnight expectations before accepting a deadline. Do not build a timetable around maximum reductions and exceptional allowances as if they were routine capacity.

Confirm the cab before costing the job.

18-tonne trucks may have day or sleeper cabs. Suitable accommodation and parking can still be necessary.

Include the onward plan and required rest, not only arrival at the delivery point.

Day cab and sleeper cab rigid trucks with plan-view cab insets. The day cab has seats without a berth; the sleeper has a transverse berth behind the seats. Suitable rest, parking, accommodation or transfers and next-day driving allowance must be planned.
Confirm the actual cab and duty plan. Regular weekly rest must not be taken in the vehicle.
12 / The vehicle and operation must both qualify

Other operating and international considerations

The booking needs suitable people, equipment, records and route arrangements as well as enough cargo space.

Licence, professional qualification and operator arrangements.

An 18-tonne rigid normally requires category C entitlement. Category C1 is limited to vehicles over 3.5 tonnes up to 7.5 tonnes and is not enough for an 18-tonner. Trailer entitlement must be checked separately. A car licence is not proof of entitlement to drive this truck.

Professional Driver CPC requirements apply where relevant, with exemptions assessed separately. Business goods-vehicle operation over 3.5 tonnes normally requires the appropriate operator licensing arrangements. Licence entitlement alone does not establish that the whole commercial operation is compliant.

Road limits and the limiter are different.

For goods vehicles exceeding 7.5 tonnes, national limits outside built-up areas are generally 50 mph on single carriageways, 60 mph on dual carriageways and 60 mph on motorways in England and Wales. In Scotland the corresponding general limits are 40, 50 and 60 mph. Lower posted limits, road conditions, towing and other applicable restrictions still matter.

Truck speed limiters can hold the vehicle below the road’s maximum limit. A limiter setting is not an average journey speed. Urban stops, traffic and breaks make a mileage divided by motorway speed estimate unsuitable for a delivery promise.

European work needs a route-specific check.

Discuss documents, customs arrangements, border and ferry time, local vehicle rules, emissions zones, drivers’ hours regime and suitable rest stops. Applicable assimilated or AETR rules depend on the operation and route.

For normal in-scope UK–EU international HGV work, smart tachograph 2 retrofit deadlines for older analogue/digital and smart 1 units have passed. Check the actual truck, route, registration date and current requirements. Domestic-only vehicles have different fitment rules. Do not assume rules stop applying because the vehicle is small compared with an artic. An international quote needs more than the collection and delivery postcodes.

Clean-air access depends on the actual vehicle.

Check the registration, applicable emissions standard and the destination’s current scheme. A diesel truck’s Euro standard relates to regulated pollutants; it does not establish its CO₂ output or guarantee free access everywhere.

London’s ULEZ and LEZ have different vehicle scopes. London’s Direct Vision Standard safety-permit scheme covers goods vehicles over 12 tonnes, including this category. Check the actual truck’s current permit and required safety equipment; Euro VI emissions compliance does not establish Direct Vision compliance. Being outside one scheme does not remove other road, loading or emissions restrictions.

Vans are also subject to applicable driving, working and fatigue rules. Moving up to a truck makes the tachograph and duty structure especially visible, but smaller vehicles should not be described as unrestricted.

Use the official licence categories, operator guidance and speed-limit table for current detail. Check destination schemes directly when planning the route.

13 / Loaded economy and all the mileage

18-tonne truck fuel economy and running costs

Include collection positioning, freight, stops, auxiliary equipment and the onward plan when assessing the real job.

There is no single 18-tonne MPG figure.

Body height, wheelbase, engine, gearbox, tyres, load and road conditions affect economy. A large box moving through air can use more fuel than a smaller body, while repeated urban acceleration differs from a steady road run.

Use consumption relevant to the actual completed truck and its work. Figures for an unbodied chassis, a different gross rating or an empty test run should not be treated as loaded delivery performance.

A fully loaded truck can use substantially more fuel.

Extra mass increases the work of acceleration and climbing. Stop-start deliveries, hills, headwinds, idling and refrigeration can add energy demand. There is no defensible universal “fully loaded percentage” for every truck.

Loading can change both diesel consumption and electric range. Measured whole-job consumption is more useful than assuming the same economy on the approach, loaded journey and onward run.

The diesel assumptions of 10, 13 and 16 imperial mpg and electric assumptions of 160, 200 and 240 metered kWh/100 miles are deliberately varied arithmetic inputs, not measured class averages or predicted performance. They show sensitivity to energy use and tariff. Establish the actual completed vehicles, equivalent load, route and charging plan before comparison.

Fuel cost is one part of the courier price.

Suppose an illustrative job includes 25 miles to collection, 100 loaded miles and 25 onward miles. The truck travels 150 miles, rather than just the 100 shown between the two customer sites.

If the 50 approach/onward miles achieve an assumed 16 imperial mpg and the 100 loaded miles achieve 12 mpg, fuel use is about 52.09 litres. At the assumed £1.60/L that is £83.34 in diesel alone. The assumptions are examples, not a price or economy promise.

Driver time, loading and waiting, legal breaks, vehicle availability, tyres and maintenance, equipment, parking, accommodation, insurance, tolls and the rest of the operation also affect the quote. A truck’s cost is not its fuel receipt with a small mark-up.

Price the complete movement.

This 150-mile example includes approach and onward travel. The loaded 100-mile leg can have different consumption from the other legs.

Time, equipment, breaks, waiting and accommodation are additional costs.

An empty 25-mile approach, a loaded 100-mile delivery and an empty 25-mile onward leg total 150 miles. Energy, driver time, loading, waiting, breaks and onward planning all contribute to the complete journey.
Illustrative journey. Actual positioning and onward mileage vary.
14 / Match the energy system to the work

Diesel and electric 18-tonne trucks

The best operating choice depends on the load, route, timetable, charging access and the completed vehicle.

Diesel: established range and quick refuelling.

Diesel can be practical for urgent long distances, changing routes and work where dependable truck charging is unavailable. Refuelling is usually quicker and more flexible than arranging a substantial battery recharge.

That flexibility has costs: combustion emissions, fuel-supply emissions, noise, maintenance and possible local clean-air requirements. Diesel does not remove the driver’s break and rest obligations.

Electric: useful where the whole route can be supported.

Battery-electric rigid trucks exist in this part of the market. Volvo’s FL Electric range includes configurations with a stated gross combination weight up to 18.6 tonnes. Gross combination weight is not the freight payload, and a range-level specification does not establish the permitted solo gross weight or capacity of a particular completed truck. Battery, wheelbase and body choices require checking.

A suitable electric truck can work well for a predictable delivery round, depot charging and urban stops. It has no exhaust CO₂ while driving, but electricity generation, production of the vehicle and non-exhaust particles remain relevant.

Urgent long-distance work needs a credible charging plan.

Do not substitute an electric truck into a time-critical long-distance job using a headline range alone. Start-of-job charge, loaded route, weather, refrigeration, approach mileage, reserve and the onward requirement all matter.

A required charging stop can add detour, queue, connection and charging time. The charger must be accessible to the complete truck and compatible with it. Advertised peak power is not the average rate through a whole recharge. These uncertainties can make electric unsuitable for a particular urgent job.

Where the journey fits confirmed usable range, or dependable charging fits a realistic timetable, an electric truck may be appropriate. A charging stop only doubles as a driver break when the applicable conditions are actually met.

Petrol and plug-in hybrid choices seen in some van ranges should not be assumed to be equivalent mainstream 18-tonne truck options. We do not invent a petrol or hybrid truck comparison with unverified capacity. Alternative fuels also need evidence for the actual engine approval, supply chain and emissions boundary.

Compare completed diesel and electric vehicles doing equivalent work. Battery mass, equipment and body construction can alter available freight capacity. Manufacturer information is available for the Volvo FL Electric range. This is a model example, not a claim of Synergix availability, a 9,000 kg electric payload or a guaranteed route range.

15 / Clear boundaries and visible assumptions

CO₂, fuel supply and truck lifecycle emissions

Explain what a number includes before using it to compare vehicles or claim an environmental benefit.

CO₂ and CO₂e are different measures.

CO₂ measures carbon dioxide. CO₂e expresses several greenhouse gases on a common basis. Tailpipe CO₂, fuel combustion CO₂e, upstream fuel production and whole-vehicle lifecycle emissions should not be labelled as the same result.

Euro VI pollutant compliance is not a CO₂ rating. An electric truck has zero exhaust CO₂, while its electricity and manufacture can still produce greenhouse gases.

The boundary changes the answer.

For diesel, include the litres consumed and the chosen combustion and fuel-supply factors. For electric, use metered energy or adjust battery-delivered energy for charging losses; do not add the same losses twice.

For refrigerated work, include cooling energy on the appropriate basis. Separately fuelled refrigeration needs its own consumption; electric auxiliary demand must be included once, not double-counted. Relevant refrigerant leakage is an additional greenhouse-gas source. Vehicle manufacture, replacement components and end-of-life are further lifecycle terms.

The energy tables use the UK Government’s 2026 reporting factors: average-blend diesel combustion 2.58354 kg CO₂e/L plus fuel supply 0.61101, totalling 3.19455 kg CO₂e/L. For UK electricity, generation, transmission/distribution and their upstream terms total 0.18436 kg CO₂e/kWh. These are reporting factors, not live measurements of the particular fuel or charger.

This is the Government reporting treatment: biofuel-derived CO₂ is reported separately outside the main scopes. The diesel factor is therefore not a measure of every molecule emitted at the exhaust. A full lifecycle assessment needs an appropriate, consistently applied method. Tariffs and prices above are assumptions, not current market quotations.

Read the official 2026 conversion factors. The examples hold those factors constant; they do not forecast future grid changes or claim a company fleet average.

250,000-mile operating-emissions sensitivity. Manufacture is excluded from these numbers. Equivalent work and usable capacity have not been established.
Scenario assumptionLifetime energyOperating greenhouse gases
Diesel at 10 imperial mpg113,652 litres363.07 tonnes CO₂e
Diesel at 13 imperial mpg87,425 litres279.28 tonnes CO₂e
Diesel at 16 imperial mpg71,033 litres226.92 tonnes CO₂e
Electric at 160 metered kWh/100 miles400,000 kWh73.74 tonnes CO₂e
Electric at 200 metered kWh/100 miles500,000 kWh92.18 tonnes CO₂e
Electric at 240 metered kWh/100 miles600,000 kWh110.62 tonnes CO₂e

Including manufacture needs real production data.

In the middle assumptions, diesel operation at 13 mpg produces about 279.28 tonnes CO₂e over 250,000 miles; electric operation at 200 metered kWh/100 miles produces about 92.18 tonnes CO₂e. These figures illustrate operating emissions under stated assumptions. They do not establish equivalent vehicle capacity or a complete lifetime result.

A fuller diesel total is its vehicle/body manufacturing emissions + 279.28 tonnes + applicable replacements and end-of-life. A fuller electric total is its vehicle/body/battery manufacturing emissions + 92.18 tonnes + applicable replacements and end-of-life. Comparable production evidence is needed for those missing terms.

We do not assign an invented production footprint or battery-replacement count to an 18-tonne truck. Nor does a 250,000-mile illustration promise that a vehicle, battery or body will last that distance without repairs or replacement.

An electric vehicle with greater production emissions can offset that difference through lower operating emissions, depending on the real energy use and electricity supply. The indicative break-even distance is the extra production emissions divided by the operating-emissions saving per mile, with consistent units. If that saving is zero or negative, this simple calculation does not show a break-even.

Choosing a suitable smaller vehicle, avoiding unnecessary journeys and planning loading efficiently can reduce energy demand. Sending two under-capacity vehicles instead of one suitable truck may change the result in the other direction. Compare the complete job, not one unloaded vehicle-mile.

Tailpipe example over 100 miles.

100 miles equals 160.9344 km. At an assumed 1,100 g CO₂/km, the result is 177.03 kg CO₂. This cannot be compared directly with electricity-supply CO₂e as if both covered the same boundary.

Report the job boundary.

State whether positioning, loaded mileage, onward travel and auxiliary energy are included. Use the same boundary and compatible measurement basis across the options. A precise-looking decimal does not remove uncertain assumptions.

Compare the same work and boundary.

Tailpipe CO2, operating CO2e and whole-lifecycle emissions answer different questions.

Use actual energy data and comparable production evidence before making a full lifetime claim.

Diesel and electric process rows each contain manufacture, energy supply, journey use, maintenance and end of life. The operating boundary surrounds only energy supply and journey use; the lifecycle boundary contains every stage. Diesel has tailpipe CO2. Electric has no tailpipe CO2, but supply and manufacture still count.
Manufacturing footprints depend on the actual vehicle and battery. Do not substitute an invented production figure.
16 / The vehicle is one part of the service

Courier work, haulage and specialist deliveries

Match the body, equipment and people to the job, from an urgent one-off delivery to a regular distribution plan.

Urgent dedicated transport.

A suitable truck can take an agreed consignment directly between sites without relying on a parcel sorting network. Dedicated allocation can help with bulky freight, urgent stock and production equipment.

The delivery commitment still depends on availability, loading, road access and a lawful duty plan. Call with the deadline when the consignment is time-sensitive; do not assume a particular truck can be at every postcode within a fixed time.

Regular haulage and retail distribution.

Planned supplier collections, replenishment, repeat business deliveries and agreed multi-stop work can suit this vehicle size. Confirm quantities, handling, delivery order, appointment windows and expected site time.

A fourteen-UK-pallet floor guide is not proof that the truck can carry fourteen heavy pallets on a round. The combined weight, remaining stability and access to each drop must be checked.

Warehousing and two-person delivery.

Transport can form part of an agreed warehousing and distribution arrangement. Tell us about storage, stock movements, booking-in and the handling needed before allocation.

For home or business delivery, specify whether you need two-person handling, room-of-choice delivery, stairs, unpacking or assembly. These are additional requirements, not automatic benefits of ordering an 18-tonne truck.

Specialist and temperature-sensitive work.

Discuss fragile equipment, controlled temperatures, event schedules and other special requirements before booking. Vehicle availability, clean handling, securing, monitoring and product compatibility must be established.

Event refrigeration is a separate service requirement from merely sending a refrigerated delivery truck. Agree the cooling/storage arrangement, operating hours and power provision needed at the venue.

Explore our transport and logistics services for the wider business. Select the relevant service as well as the vehicle, so responsibility for equipment, access and handling is clear.

Clear details help us give a useful answer.

Tell us what the goods are, how they are packaged, the total weight and heaviest item, and what needs to happen at each site. If the first suggested truck cannot meet all those requirements, we can assess a suitable alternative.

A quote, an enquiry reference or a vehicle guide is not a confirmed booking. Agree the vehicle, service, handling and delivery arrangements before dispatch.

17 / Before you commit

18-tonne truck prices and booking checklist

Give us the full job, including the loading bay, so we can assess a realistic price and workable delivery plan.

What changes the price?

Collection positioning and total mileage, vehicle availability, the selected body, individual item weight, handling equipment, staff, waiting, appointments, tolls, clean-air charges and parking all matter.

Overnight work can include accommodation and associated parking or transfers. Driver time includes duties outside the loaded road journey. A last-minute loading-bay change may require a different vehicle and a revised plan.

Choose enough vehicle, without ordering unnecessary size.

A 7.5-tonner may be preferable for a smaller consignment and a restrictive bay. A suitable 18-tonner can add useful capacity for heavier freight. A 26-tonner may avoid several movements where the weight, volume and site access justify the step up.

Price comparisons need the same service assumptions. A cheaper vehicle without the required unloading method or bay clearance is not an equivalent option.

  • Collection and delivery addresses, correct entrances, site contacts and requested dates.
  • Packaged length, width and height of every differently sized item, including pallet, overhang and wrapping.
  • Total consignment weight, individual pallet/item weights and whether the weight has been measured.
  • Body requirement: box, curtainside or the agreed temperature-controlled specification.
  • Loading and unloading method at both ends: forklift, dock, tail lift, pallet truck and any additional staff.
  • Individual pallet at 800 kg or more requiring pallet-truck handling: request an electric pump truck.
  • Bay and route limits: maximum vehicle height, length, width and gross weight, turning space, ramps and unloading area.
  • Opening hours, booked slots, loading time, expected queues and the firm delivery deadline.
  • Goods description, temperature requirements, fragile/high-value details and securing or handling instructions.
  • Overnight expectations, European documents and any onward or return collection required.

18-tonne truck courier FAQs

Find the practical detail on weight, fit, handling, costs and the journey.

Vehicle size, body and freight

What is an 18-tonne truck?

It is a goods vehicle in the 18,000 kg gross weight category. That gross figure includes the completed truck, people, fuel, equipment and freight. It does not mean the truck can carry 18,000 kg of goods.

How much can a Synergix 18-tonne truck carry?

Our initial planning guide is up to 9,000 kg total consignment weight. The actual completed truck, equipment, ready-to-work weight, axle limits and handling requirements must be checked before booking. A heavier body or conversion may leave less capacity.

Why do other 18-tonne trucks advertise different payloads?

Chassis specifications, body construction, length, roof height, tail lifts, refrigeration, fuel and equipment vary. The ready-to-work vehicle weight changes the remaining freight allowance. A different operator’s figure is not proof that our assigned truck can accept that load.

Does the 9,000 kg allowance include the pallets and packaging?

Yes. Give the total loaded consignment weight, including pallets, packaging, wrapping and anything else travelling as freight. Equipment carried on the vehicle also needs accounting for in the ready-to-work capacity check.

What are the planning dimensions?

Our initial guide is 7.5 m load length × 2.4 m internal width × 2.5 m internal height. These are planning references, not guaranteed door or body clearances. Body builders and equipment specifications vary. Confirm the completed vehicle for a tight or unusual load.

What is the planning load volume?

Multiplying 7.5 × 2.4 × 2.5 gives 45 cubic metres as a rectangular planning envelope. That is not a guarantee that every cubic metre is usable. Doors, packaging, obstructions, handling and restraint can limit an individual shipment.

Why is the dimension diagram different from the booking figures?

The drawing illustrates one body at approximately 8,000 × 2,460 × 2,620 mm internally. Our initial category guide is 7,500 × 2,400 × 2,500 mm. The illustrated truck is an example rather than the assigned vehicle. Neither set establishes a guaranteed door opening. Confirm the actual body and freight fit.

Does a 7.5 m body mean a 7.5 m item will fit?

No. The opening, packaging, loading angle, internal obstructions, usable floor and room for handling and restraint need checking. An item using every centimetre of nominal length may leave no workable clearance.

Are all 18-tonne trucks the same outside size?

No. Wheelbase, chassis, body builder, roof, lift, mirrors and refrigeration equipment change the outside dimensions. Send access limits and ask for the completed vehicle’s actual height, length and width. The gross weight category cannot establish whether it fits a loading bay.

Which body types can I request?

Box and curtainside are the usual choices for this guide. Refrigerated or temperature-controlled transport requires an agreed specification. Refrigerated retail trucks normally have tail lifts, while dry box and curtainside equipment must be requested and confirmed. Tell us the goods and loading method.

When is a box truck suitable?

It suits compatible enclosed freight that can be loaded and unloaded using the agreed rear or fitted side access. Packaged retail stock, furniture, appliances, cartons and suitable pallets are examples. Confirm protection, securing, openings and the unloading method.

When is a curtainsider preferable?

It can help when a suitable forklift needs side access to long pallets, awkward goods or a planned unloading sequence. Posts and openings still matter. It does not supply a forklift at delivery or make a long pallet suitable for rear tail-lift unloading.

Can I book a refrigerated 18-tonne truck?

Discuss the required temperature, goods, packaged size, total weight, loading temperature and monitoring needs. Purpose-built insulation is incorporated into the body, so internal load space can be comparable with a similarly sized dry box. Added refrigeration, body and lift weight can reduce payload. Refrigerated retail vehicles normally have tail lifts. Confirm the actual body, cooling obstructions, airflow, platform and working freight allowance.

Do 18-tonne trucks have sleeper cabs?

They can have day or sleeper cabs. Confirm the actual allocation. A suitable sleeper may support permitted daily-rest arrangements, while a day-cab job away from base may need accommodation and parking. Regular weekly rest cannot be taken in the vehicle.

Pallets, tail lifts and handling

How many pallets can an 18-tonne truck carry?

Our initial guide is up to 14 suitable UK pallets at 120 × 100 cm, or up to 18 Euro pallets at 120 × 80 cm in an appropriate body and layout. Loaded footprint, wrapping, restraint, openings and total weight must be checked. These are alternative counts, not 32 pallets together.

Can it take fourteen standard UK pallets?

Fourteen nominal bases can occupy 700 × 240 cm in seven rows of two, rotated so each base uses 100 cm along the truck and 120 cm across it. This requires the full 240 cm clear width before any overhang or working space. Confirm compatible fork entry, transfer and restraint.

How many Euro pallets can it carry?

Up to 18 nominal bases can occupy 720 × 240 cm in nine rows of two. There is no nominal width margin at a 240 cm clear body. A narrower 750 × 220 cm illustrative body can use a fifteen-base mixed layout occupying 720 × 200 cm. The actual loaded footprint, handling and weight decide acceptance.

Can an 8 m body fit twenty Euro pallets?

Twenty nominal bases can mathematically occupy 800 × 240 cm in ten rows of two. This is a zero-length-margin arrangement requiring the actual longer body and full width. It is not our initial booking guide and does not establish clearance for loaded overhang, handling or restraint.

Does a Euro pallet give me more payload?

No. A smaller pallet footprint may change the space arrangement, but the completed vehicle’s freight and axle limits remain. Confirm the count and loaded size separately instead of substituting a new pallet allowance without checks.

Can fourteen 650 kg pallets travel on this guide?

Fourteen loaded pallets at 650 kg total 9,100 kg, above our 9,000 kg initial freight guide. Eighteen Euro pallets at 550 kg each total 9,900 kg. A suitable larger vehicle or another agreed plan is needed. Empty floor space does not permit excess weight.

Can one item use nearly all the payload?

Only if the actual truck, floor, weight distribution, loading and unloading method can accept it. A single concentrated load can present different floor and axle issues from several lighter pallets. Send the item’s size, weight, support positions and centre-of-gravity concerns.

Is a tail lift included with every truck?

Not every dry box or curtainsider does. Refrigerated retail trucks normally have a tail lift. Confirm it explicitly and provide the heaviest item and handling method. The selected lift’s capacity, platform dimensions, load centre and operating conditions must be suitable. The truck’s freight payload is not its tail-lift rating.

How much weight does a tail lift remove from payload?

Its installed mass and associated equipment contribute to vehicle weight. The reduction depends on the actual lift and completed body, so a fixed deduction should not be applied to every truck. Confirm ready-to-work freight capacity for the assigned vehicle.

Does the lift rating include the pallet truck?

The total load on the platform must comply with the applicable lift specification, including handling equipment and any permitted operator mass. A pallet matching the nominal lift rating can exceed it once those other loads are added.

When do I need an electric pump truck?

For an individual loaded pallet at 800 kg or more requiring pallet-truck handling, request an electric pump truck under Synergix’s booking rule. Lighter loads may also require powered handling. This does not guarantee that the lift, ground or delivery route is suitable.

Can a 3 m pallet be unloaded using a rear tail lift?

Do not assume so because it fits inside the truck. Platform support, pallet-truck engagement, load centre, rear opening and manoeuvring space all need assessment. A suitable curtainsider with forklift handling at both ends may be a different solution.

Can the driver take a pallet across gravel or grass?

A standard pallet truck is intended for a suitable firm surface and cannot be assumed to cross soft ground, gravel, steep slopes or rough thresholds. Describe the full path and unloading point so a workable method can be assessed.

Does a tail lift mean the truck can unload itself anywhere?

It provides an agreed way to transfer compatible goods between truck and ground. It still needs suitable freight, equipment, ground and safe operating space. Building entry, stairs and long or unusually heavy items require separate arrangements.

Is a forklift at collection enough?

No. Confirm a compatible unloading method at delivery too. A side-loaded pallet may not be transferable using the destination’s rear lift arrangement. Equipment capacity must be assessed at the actual load centre, not just by a headline forklift rating.

Can I use a loading dock instead of a lift?

Possibly, if the truck floor height, approach, doors, lift stowage and dock or leveller are compatible. Give the site’s vehicle and loading requirements. A dock designed for another body or vehicle size is not automatically suitable.

Can I stack pallets?

Only where the goods, packaging, pallet supports, available height, stability and handling method allow it. Stacking does not increase the payload. Do not load one pallet on another merely to reach an advertised position count.

Are curtains enough to secure the goods?

Do not assume so. The load needs a suitable securing arrangement for the actual body, freight and equipment. Some rated structures have specific conditions, but a standard curtain is not a generic restraint system. Packaging wrap also does not secure the pallet to the truck.

City centres, homes and loading bays

Can an 18-tonne truck deliver to residential premises?

It can where the legal approach, physical dimensions, parking and unloading arrangements permit. A smaller 7.5-tonne truck or Luton may be necessary for restricted streets or bays. An access exemption does not make a large body fit through a small entrance.

Are 18-tonne trucks allowed in city centres?

There is no universal city-centre rule. Traffic orders, signs, loading times, environmental zones, permits and physical access decide the result. A qualifying delivery exemption can matter, but it must apply to the actual restriction and destination.

Will it fit a shopping-centre loading bay?

Only after checking. Covered bays, height barriers, ramps and turning areas vary, and some sites require a Luton or smaller vehicle. Ask the receiving site for its maximum vehicle dimensions, gross limit, correct entrance and handling instructions before allocation.

Why can a booked truck fit the goods but fail at the building?

Freight size and outside vehicle size are separate checks. A taller body or roof-mounted equipment can exceed the loading-bay height even when the consignment is small. Mirrors, ramps, turns, tail overhang and lift operating space can cause other problems.

Does a bay allowing 18 tonnes accept every 18-tonne truck?

No. A gross-weight allowance does not establish height, length or width clearance. Some covered shopping-centre bays are limited to 7.5-tonne trucks or Lutons. Confirm the complete vehicle dimensions, correct entrance and handling rules.

What if the site only permits a Luton?

Tell us before booking. Check that the consignment fits the chosen Luton and its actual capacity; our tail-lift Luton planning allowance is up to 900 kg. A heavier load may require separate trips or another agreed arrangement, rather than overloading a smaller vehicle.

Does travelling empty remove a weight restriction?

Not necessarily. Restrictions can be defined by permitted gross weight, actual weight, vehicle type or the relevant order and signs. Do not assume an empty truck is exempt. The route must be assessed against the restriction that actually applies.

What information do you need for restricted access?

Send the correct delivery entrance, maximum permitted height, length, width and gross weight, bay instructions, ramp and turning restrictions, booked slot, site contact and unloading method. Photos or site documents can help, but actual clearance must be confirmed.

Is room-of-choice home delivery included?

No. State whether you need building entry, stairs, two-person handling, unpacking or assembly. A standard tail-lift delivery should not be understood as taking every item into a home. Service and access must be agreed.

Should I choose a 7.5-tonne, 18-tonne or 26-tonne truck?

Choose the smallest suitable completed vehicle that can carry and handle the freight and reach the site. Our initial freight guides are 2,400 kg for 7.5t, 9,000 kg for 18t and 15,000 kg for 26t, subject to the actual body and equipment. A heavier rating does not guarantee more pallet space.

Access exemptions and choosing a larger rigid

Can an 18-tonne truck pass a 7.5-tonne sign marked “except for access”?

It may be permitted for a qualifying delivery or collection within the restricted area, under the applicable exemption. Check the exact sign, supplementary plate, times and traffic order, including whether another route is required. It is not permission to use the road as a shortcut. Physical clearance and all other restrictions still apply.

Does every 7.5-tonne sign have an access exemption?

No. The exemption must actually apply to that restriction. Structural bridge limits, other vehicle prohibitions and private site rules need their own assessment. Do not infer an exemption from the weight number alone.

What is the difference between an environmental and structural weight limit?

A lorry-symbol environmental restriction is normally based on plated maximum gross weight, so travelling empty does not remove it. A structural weight restriction protects the road or bridge and can also be based on plated maximum gross weight. An empty-vehicle exception must actually be provided. Check the signed weight basis and any axle limit. Read the specific sign and order; a delivery elsewhere does not override it.

Can a 9,000 kg shipment overload an axle while staying under 18 tonnes?

Yes. Total gross weight and each axle limit are separate constraints. A concentrated item, rear-heavy loading or a change after unloading can create an axle problem. The distribution, support and delivery sequence must be checked.

Why choose an 18-tonne rigid instead of an articulated lorry?

Where its body and payload are enough, a rigid can suit sites and handling arrangements that are less practical for an articulated combination. This is not a universal turning or access guarantee. Check the actual wheelbase, tail sweep, manoeuvring space and entrance.

Why not book a 26-tonne truck for every job?

The additional weight rating can help dense freight, but a larger body or chassis can increase cost and make access harder. If an 18-tonne truck meets weight, space, handling and route needs, unnecessary size may add little value. Conversely, a smaller truck must never be overloaded to save money.

Do 18-tonne trucks need a London HGV safety permit?

The TfL scheme applies to HGVs over 12 tonnes gross vehicle weight in its Greater London area. An in-scope 18-tonne truck needs a valid permit and the applicable vehicle safety requirements. This is separate from clean-air compliance, local lorry controls and delivery access.

Can a curtainsider take a crane or truck-mounted forklift automatically?

No. Flatbeds, HIAB cranes and truck-mounted forklifts need a separately agreed specification. Their equipment and mounting affect ready-to-work mass, dimensions and axle loading. A standard curtainsider booking does not supply those capabilities.

Driver time, waiting and overnight work

Does a commercial 18-tonne delivery normally need a tachograph?

Yes, normal in-scope commercial goods work generally does. Specific exemptions must be assessed against the operation. A time-sensitive booking is not itself an exemption, and empty positioning for an in-scope job is not automatically outside the rules.

How many hours can the driver drive?

The general daily driving limit is nine hours, extendable to ten twice a week, with separate weekly and two-week limits. Previous activity, rest and breaks also matter. The full allowance cannot be assumed available when a new enquiry arrives.

When is a driving break needed?

A qualifying break totalling at least 45 minutes is needed by four hours 30 minutes of accumulated driving, unless an appropriate rest begins. The permitted split is at least 15 minutes followed by at least 30 minutes. Loading and unloading do not reset that clock.

Does loading count towards working time?

Relevant loading, unloading, checks, administration and maintenance count as work for in-scope mobile workers. Driving limits and working-time limits operate together. A long loading delay can therefore affect the schedule even though the truck has not covered much distance.

Can a site queue count as rest?

Not automatically. The duties and whether a waiting period qualifies as availability, a break or rest must be assessed. A driver required to supervise goods or move the truck repeatedly is not simply free to rest.

Can the driver unload while taking a break?

Unloading is work. A parked vehicle does not turn a handling task into a qualifying break. A real break needs the applicable freedom from duties, and working-time and driving-break requirements must both be considered.

Why does a delay at collection change the delivery plan?

It can use working time, move arrival beyond a booked slot and reduce the room for onward travel and rest. Tell us when the load will actually be ready and update the expected delay. The solution may need a revised schedule or transport arrangement.

Can you run a truck overnight?

Discuss the route and deadline. A suitable vehicle, available qualified driver and lawful duty plan are needed. Night-work rules, previous activity, site hours, accommodation and onward travel can affect feasibility and price.

Why might a hotel be included in the quote?

The truck may have a day cab and the assignment may require an overnight rest away from base. Suitable accommodation, parking and transfers can add cost. A driver should not be expected to sleep on seats or keep moving the truck during required rest.

Does a sleeper cab remove the hotel requirement?

It can change some daily-rest arrangements, subject to suitable facilities and the applicable rules. It does not permit regular weekly rest in the vehicle or remove accommodation needs in every case. Confirm the actual truck and duty plan.

Does two-person delivery mean two drivers?

No. A second person may be supplied for handling rather than qualified multi-manning. Both are distinct requirements. Additional personnel and driver arrangements must be agreed for the actual job.

Are vans free of driving and working rules?

No. Applicable domestic or international rules and fatigue responsibilities still matter. A truck guide makes the tachograph and driving/rest structure especially prominent, but smaller vehicles should not be presented as unrestricted.

Fuel, electric trucks and emissions

What fuel economy does an 18-tonne truck achieve?

It depends on the completed body, drivetrain, load, route and conditions. This page uses clearly labelled arithmetic scenarios, not a claimed Synergix average. Use relevant measured consumption or verified model information for the actual work.

Will a fully loaded truck use more fuel?

It can use substantially more, particularly in stop-start traffic and on hills. Body aerodynamics, speed, weather, tyres, idling and refrigeration also matter. There is no single percentage penalty that can safely be applied to every completed truck.

Why include miles before collection?

The truck needs to reach the goods. Relevant positioning and onward travel use energy and driver time even when the customer’s site-to-site distance is shorter. A useful whole-job assessment includes that plan rather than counting only loaded miles.

Do electric rigid trucks in this part of the market exist?

Yes. Volvo’s FL Electric is an example, with configuration-dependent gross ratings, batteries, wheelbases and bodies. Verify the permitted solo gross weight and payload of the actual completed vehicle. The existence of a model does not guarantee Synergix availability or equivalence to a diesel carrying 9,000 kg.

Are electric trucks suitable for urgent long distances?

Only where the load, usable range and charging arrangements fit a credible timetable. Required charging can add detours, queues and uncertain duration, making some urgent jobs unsuitable. A headline range or peak charging rate is not enough to confirm the job.

Can charging happen during the driver’s break?

Sometimes, if the stop and duties meet the relevant break conditions. Connecting, moving, monitoring or dealing with a charger may involve work. Do not automatically subtract the whole charging time from the delivery schedule as if it were already a required rest.

Is diesel always better than electric for courier work?

No single answer covers every job. Diesel can offer useful refuelling and route flexibility for urgent long distances. Electric can suit predictable routes with suitable capacity and dependable charging. Compare the completed vehicles doing the required work.

Why is there no equivalent petrol-truck scenario?

Petrol and plug-in hybrid choices in some van ranges do not establish comparable mainstream 18-tonne truck options. We do not assign an invented petrol truck payload or consumption figure. A meaningful comparison needs real equivalent specifications.

How much CO₂ does the truck produce per 100 miles?

It needs an actual rate or fuel use and a stated boundary. At an assumed 1,100 g tailpipe CO₂/km, 100 miles produces 177.03 kg CO₂. The separate tables use fuel/electricity supply CO₂e factors with explicitly assumed energy consumption. Neither is a measured company average.

Does zero tailpipe CO₂ mean zero lifecycle emissions?

No. Electricity supply, vehicle and battery production, replacement components and end-of-life can produce emissions. Non-exhaust particles also remain. Keep exhaust CO₂, operating CO₂e and full lifecycle emissions separate.

Can you calculate all emissions over 250,000 miles?

We can show operating scenarios using stated consumption and reporting factors. A complete lifecycle total also needs comparable manufacture, replacements and end-of-life data. This page leaves those unknown terms explicit instead of inventing production footprints or battery replacement counts.

Does refrigeration change the emissions result?

Yes. Include the cooling energy and any separately fuelled equipment on the appropriate basis. Insulation and machinery can also affect freight capacity and vehicle energy use. A standard dry-body scenario should not be applied unchanged to every refrigerated job.

Enquiries, prices and service details

Can I book urgent or same-day 18-tonne transport?

Call with the load, route, handling and deadline. Availability and a realistic lawful delivery plan must be checked. An urgent enquiry is not a guaranteed dispatch time, and a quote is not a confirmed booking.

Can I arrange regular haulage or retail deliveries?

Discuss quantities, repeat dates, delivery order, booked slots and handling at every site. The vehicle can form part of an agreed distribution plan, with the body and freight limits checked against the actual work.

What should I send for a quote?

Send packaged dimensions, total and individual weights, goods description, addresses, dates, deadline, body requirements, loading/unloading methods and site restrictions. Include loading-bay instructions, waiting expectations and any overnight or European requirements.

Can I get a fixed price from mileage alone?

Mileage is only one input. Vehicle availability, body, freight and handling, personnel, waiting, legal duty time, charges and possible accommodation affect cost. Two quotes are only comparable when the service and access assumptions agree.

Can warehousing or specialist handling be included?

Discuss the full requirement before booking, including storage, stock movements, two-person handling, controlled temperature or fragile equipment. These are service arrangements, not automatic features of a truck category.

Where should I enquire?

Use the online quote enquiry or call 01782 911 181 for a time-sensitive job. Written sales enquiries can go to sales@synergixsameday.com. The vehicle, handling and delivery plan need confirmation before dispatch.
