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.
What should sites in Derbyshire consider?
Every leveller recommendation we make for a dock in Derbyshire follows a measured survey of the pit, dock height and the trailers you actually receive. Ageing levellers in older docks around Derbyshire can often be replaced like for like in the existing pit, avoiding new concrete work if the pit is sound.
Fitting out a new warehouse in Derbyshire with pre-formed pits makes swing-lip levellers a straightforward choice for most general loading from day one.
Here is what happens after you contact us about a site in Derbyshire. We arrange a free survey, measure up and send a fixed written quote. If you go ahead, we manage the whole job, including ordering, delivery and coordination with your site team. Specialist installation engineers working under our management do the fitting, at times built around your loading schedule, with out-of-hours work by arrangement. Testing and handover documents close the job.
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.
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.

Planning, building control and safety law in England
Sites in Derbyshire 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
Can you work alongside our main contractor on a new build in Derbyshire?
Yes. For new warehouses and fit-outs, we can supply and install the dock package as part of a wider project, working to the main contractor's programme, site rules and permits. We will need drawings, dock levels and the programme, and we coordinate pit details, power supplies and door openings with the relevant trades before installation begins.
What details do you need from us to quote for swing-lip dock levellers?
To get started, send the site address in Derbyshire, 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.
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.
How long does a replacement leveller take to arrive?
Lead times depend on size, specification and the manufacturer, and we confirm them in the written quote. The existing leveller can usually stay in use until the replacement is on site, so the bay is only closed for the installation itself.
