A swing-lip dock leveller is a hydraulic ramp set into a pit at the dock edge, with a hinged steel lip along its front. When a trailer is docked the platform rises, the lip swings out, and the platform lowers until the lip rests on the trailer bed, forming a bridge for forklifts and pallet trucks. The lip is typically about 400 to 500 mm long.
Why do sites in Wigan choose this?
Distribution warehouses in Wigan loading curtain-siders and box trailers every day are typical users of swing-lip levellers, which handle routine pallet loading well. Should a recent insurance inspection at a site in Wigan have flagged leveller defects, a survey can show whether repair or replacement makes more sense.
Mixed bays at a site in Wigan, where some trailers have tail lifts and others do not, may suit a combination of swing-lip and telescopic levellers.
Any project involving swing-lip dock levellers at a working site in Wigan takes planning. We survey free of charge, quote a fixed price in writing, and then agree a programme that keeps as much of the dock running as possible. Specialist installation engineers carry out the work under our management, out of hours if that suits you better. On completion we test each item, show your team how it operates and leave the documentation with you.
How long should a dock leveller platform be?
A leveller platform should be long enough to keep the slope gentle across the full range of trailer heights you load, because the steepest gradient decides which handling equipment can use it safely. A longer platform spreads the same height difference over a greater distance.
- Know your trailer mix: with a dock typically around 1,200 mm high and trailer beds ranging from roughly 900 to 1,600 mm, the height difference can be considerable.
- Check your equipment: low-clearance electric pallet trucks cope with less gradient than a counterbalance forklift with good ground clearance.
- Common lengths: platforms are commonly made from around 2 to 3.5 m long, with longer units where trailers sit very low or very high.
- Width: a wider platform gives more room when pallets sit close to the trailer sides.
When replacing a unit, the pit size limits what can be fitted, so we measure the pit and record your trailer heights at survey before recommending a length.
Do dock levellers have to be inspected by law?
Yes, dock levellers are work equipment and must be kept in a safe condition and inspected where deterioration could lead to danger. The law and the regulator depend on where the site is.
- Great Britain: the Provision and Use of Work Equipment Regulations 1998 (PUWER), enforced by HSE.
- Northern Ireland: PUWER (Northern Ireland) 1999, enforced by HSENI.
- Inspection interval: engineering insurers commonly inspect dock levellers under PUWER at 12-month intervals.
- LOLER: most levellers are treated as work equipment under PUWER, but one designed or used to lift people may fall under LOLER, or LOLER (Northern Ireland) 1999, with 6-monthly thorough examination. It depends on the equipment and how it is used; your insurer or competent person will confirm.
- Standard: BS EN 1398:2009 sets the safety requirements for dock levellers. It is current and under review.

Options to discuss
Standard swing-lip leveller
A hydraulic pit leveller with a hinged lip of about 400 to 500 mm, suited to general distribution with curtain-siders and box trailers.
Insulated leveller
An insulated platform with perimeter seals around the pit that reduces cold loss through the floor of the bay at chilled and frozen docks.
Which rules apply in England?
Sites in Wigan fall under the rules for England. Structural changes such as forming a new opening or a dock leveller pit may need Building Regulations approval, and external structures such as loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey and build any approvals into the plan.
Questions about swing-lip dock levellers in Wigan
What warranty comes with new loading bay equipment?
New equipment comes with the manufacturer's warranty, which varies by product. Our workmanship terms are set out in writing in the quote for your Wigan site, so you can see what is covered before you commit. Check the warranty terms for any servicing conditions, and we can quote for planned maintenance once the installation is complete.
How do you price swing-lip dock levellers for a site in Wigan?
Guide budgets for supply and fit are £5,200 to £8,800 per leveller, excluding VAT. The figure moves with size, insulation, the operator, electrics, access, any pit or groundworks and out-of-hours working. Where levellers are involved, the guide assumes an existing, sound pit. After the free survey you receive a fixed written quote, and that is the price for the agreed scope.
What details do you need from us to quote for swing-lip dock levellers?
To get started, send the site address in Wigan, the number of bays or openings, approximate sizes, and photos of the dock from inside and outside. Tell us what vehicles you load, what goods you handle and any temperature requirements. Drawings help on new builds. We then arrange the free survey and confirm the details before the written quote is issued.
What happens if a trailer pulls away with the lip on its bed?
The platform drops until its safety system stops it. Hydraulic levellers have a velocity fuse that arrests the fall, but the event can still damage the leveller and endanger anyone on it, which is why dock traffic lights, restraints and key control are used to prevent early drive-away.
Do levellers need a three-phase supply?
Most hydraulic dock levellers use a three-phase supply, although some smaller units run on single phase. When replacing like for like, the existing supply can often be reused if it is in good order. We check the supply at survey and include any electrical work in the quote.
