Draw the floor, the loading opening and the raised wings
External body length does not reveal the usable cargo floor or clear side aperture. Request dimensions to finished surfaces and mark posts, doors, locks and other intrusions. The wing operating envelope needs a separate check against the loading site.
Plot the actual packed footprint, including overhang or packaging bulge. Test allowed pallet orientations and leave the clearance required for handling and restraint. Show the unloading sequence; a full departure layout may become awkward or unbalanced after early deliveries.
Treat pallet count as a space estimate
Every position must also be reachable, securable and acceptable for floor and axle loading. Manufacturer wing-body examples explain construction concepts, but their dimensions cannot stand in for the offered body drawing.

| Decision | What to establish | Condition or limit |
|---|---|---|
| Floor geometry | Plot pallet rectangles on the finished internal floor drawing and subtract intrusions before counting positions. | Dividing external body area by pallet area overstates capacity and hides unusable strips of floor. |
| Pallet orientation | Compare permitted orientations against fork entry, cargo stability and the intended unloading side. | A rotated pallet can fit on paper yet be inaccessible to the available forklift. |
| Clear aperture | Check the loaded unit and its handling path through the smallest part of the side or rear opening. | Internal headroom does not establish opening height; raised forks and packaging must clear the actual path. |
| Wing envelope | Overlay the supplier's movement envelope on the site survey, including overhead structures and adjacent vehicles. | Clearance needs to cover movement as well as the fully open position. |
| Load position | Record pallet masses and positions on a departure and delivery-stage plan for the chassis/body review. | Passing gross weight does not by itself establish acceptable individual axle loads. |
| Floor duty | State pallet contact areas and whether loaded handling equipment will enter the body. | A uniformly distributed cargo rating is not proof of suitability for concentrated wheel or pallet-foot loads. |
| Restraint access | Leave the space needed to apply, inspect and release the specified securing equipment at each stop. | A position should not count as usable if the load cannot be secured or unloaded through the planned procedure. |
Submit a pallet plan with delivery stages
Provide unit dimensions and masses, handling equipment and representative unloading stages. Request confirmation of clear apertures, opening envelope, concentrated loads and axle reactions for the completed vehicle.
Information to prepare for this review
- Loaded pallet length, width and height, including packaging and permitted orientation
- Mass of each cargo unit, stacking restrictions and the order in which stops remove it
- Required pallet positions, occasional oversized consignments and return packaging
- Fork dimensions, handling approach, equipment capacity at the actual load centre and any on-board pallet truck
- Minimum side and rear opening requirements, floor height and dock or ramp interfaces
- Site width and overhead clearance with the truck parked in its intended unloading position
Records to request and keep
- Signed layout revision with finished internal dimensions and all locally restrictive hardware
- Pallet schedule identifying dimensions, mass, orientation, destination stop and stacking rules
- Side and rear aperture dimensions measured in the agreed open configuration
- Body opening envelope and accepted site-clearance schedule
- Loading calculation showing gross and axle outcomes for representative delivery states
- Floor specification addressing the declared pallet and handling-equipment loads
- Representative loading demonstration resolving the most restricted pallet position before final acceptance
Common mistakes and what to check instead
- Treating a generic pallet size as the loaded shipment size: Measure the packed unit and include actual wrap, crates and overhang.
- Selecting the longest body that fits the budget: Check turning access, axle loading and the value of each extra usable pallet position.
- Checking only a fully loaded departure: Review the remaining cargo after deliveries, including access to restraints and mass distribution.
Scope of this guide
No universal wing van pallet count or dimension is assigned here; body and chassis drawings determine the offered configuration.
Layout sketches are procurement inputs. The supplier must confirm structural, floor, mounting and loading suitability.
Attach one real pallet schedule and the tightest site drawing to the inquiry; request a marked-up proposal showing accepted positions and any exclusions.
