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.
How does this suit sites in Suffolk?
Ageing levellers in older docks around Suffolk can often be replaced like for like in the existing pit, avoiding new concrete work if the pit is sound. Should a recent insurance inspection at a site in Suffolk have flagged leveller defects, a survey can show whether repair or replacement makes more sense.
Operators in Suffolk who have added electric pallet trucks to their fleet may find an existing leveller too short, making a longer platform worth considering.
A single contact at Loading Bay Doors handles your project in Suffolk from start to finish. The free site survey and fixed written quote come first, with no obligation to proceed. We then book the installation for times that suit the operation, including out of hours by arrangement, and manage the specialist engineers on site. At the end we commission and test the equipment, walk your team through it and provide the documentation.
What wears out on a swing-lip dock leveller?
The lip hinge, hydraulic hoses and seals are usually the first parts to wear on a swing-lip leveller, and planned servicing finds most of these problems before they stop a bay.
- Lip hinge: takes an impact every time the lip lands, and suffers badly if trailers reverse into a lip that has not been stored.
- Hydraulics: hoses, cylinder seals and power pack oil age and can leak.
- Velocity fuse: the safety valve that stops the platform dropping if a trailer pulls away must be tested.
- Toe guards and maintenance strut: must be intact and working. HSE guidance notes guards or skirting may be needed where something could be caught.
- Dock bumpers: worn bumpers let trailers strike the leveller and dock edge.
A leveller with a cracked lip hinge, a bent platform or repeated hydraulic leaks may be better replaced than repaired. Service and repair visits are chargeable and agreed before anyone attends.
What happens when a swing-lip leveller is fitted into an existing pit?
Fitting a swing-lip leveller into an existing pit normally takes one to two working days per bay, with the bay closed throughout. The work runs in a set order:
- The old leveller is isolated, lifted out and removed from site.
- The pit is cleaned and measured, and the edge steel checked for damage.
- The new leveller is lowered in, set level, and welded or anchored to the pit steel.
- The hydraulic power pack and control panel are connected, and any interlocks wired.
- Toe guards, lip and bumpers are checked, then the leveller is run through its full range.
From your side we need the bay emptied and taken out of service, clear access for lifting equipment inside or outside the building, and a suitable power supply, which for most hydraulic levellers is three-phase. If the pit needs repairs, these are done first and can add time, which we confirm in the quote.

Questions
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 Suffolk 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.
Is VAT included in your guide prices for swing-lip dock levellers?
No. Our customers are businesses, so guide prices exclude VAT, which is added at the standard rate. The same guide range applies in Suffolk as everywhere else: for swing-lip dock levellers, it is £5,200 to £8,800 per leveller, excluding VAT. It covers supply and fit for a typical installation. Your fixed written quote after the free survey shows the net price, the VAT and exactly what is included.
What capacity of leveller do we need?
The leveller needs to be rated for the heaviest combined load of forklift and goods that will cross it, allowing for the truck moving over it. General-purpose levellers are typically rated around 60 kN, with heavier ratings for heavy goods or large forklifts. We confirm the rating after looking at your equipment.
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.
