Dock levellers and loading bays
A dock leveller bridges the gap and the height difference between the warehouse floor and the trailer bed, so forklifts and pallet trucks can drive straight in. In the UK most new docks get a hydraulic leveller in a pit, with a dock shelter or seal around the door. A complete position with a hydraulic leveller and rigid shelter typically costs £8,300 to £16,000, before VAT and the door.
Levellers are usually specified with the door, the shelter and some form of vehicle restraint as one loading bay package.
Which leveller suits the dock
- Hydraulic, swing lip
- The standard UK leveller: a steel platform in a pit, raised and lowered hydraulically, with a hinged lip that drops onto the trailer bed. Good for most curtain-sided and box trailers.
- Hydraulic, telescopic lip
- The lip slides out rather than swinging, so it can be placed precisely. Better for end-loading trailers, cold stores and sites where load stability matters.
- Edge-of-dock
- A short plate bolted to the dock face with no pit. Cheapest and quickest to fit, but it only handles small height differences.
- Shelters and seals
- A rigid frame shelter suits mixed trailer sizes; a compression seal grips the trailer for the best seal on chilled docks; an inflatable shelter seals well across a range of vehicles at a higher price.

Platform size and capacity
Levellers are sized by platform length and width and by dynamic load capacity, commonly 6 tonnes and often more for heavy goods or reach trucks. Longer platforms give a gentler slope, which matters for low pallet trucks and heavy loads. The gradient a pallet truck or forklift can manage sets the minimum length.
Pits
A hydraulic leveller sits in a concrete pit. On a new build the pit is formed with the slab; retrofitting means cutting and casting a pit in an existing floor, which adds cost and time. A box-type leveller is supplied in its own steel frame to be cast in.
Vehicle drive-away and restraint
A lorry pulling away while a forklift is on the leveller is one of the most serious loading bay risks. HSE guidance covers ways to stop it: wheel chocks, trailer restraints, interlocks between the door, the leveller and a traffic light, and a clear system of work with the drivers. A good loading bay specification includes one of these.
Bumpers and lighting
Rubber or steel dock bumpers protect the building from reversing trailers, and dock lights on swing arms light the trailer interior. Both are inexpensive and get damaged often, so allow for replacement in the maintenance budget.

How the job gets done
A leveller swap in an existing pit is often a day per position; new pits mean concrete work and curing time first.
Survey
Dock height, trailer types and bed heights, existing pits and floor condition, door sizes, what equipment drives on the leveller and how the bay is run.
Specification and price
Leveller type, platform size and capacity, shelter or seal, bumpers, lights, restraint or interlocks, and how the work will be phased around operations.
Install
Pit prepared or adjusted, leveller set and grouted, hydraulics and controls wired, shelter fixed, interlocks connected to the door.
Test and handover
Load test, safety stops checked, interlocks proved, operators shown the controls and the first service booked.
