An edge-of-dock leveller is a compact leveller mounted on the front face or top edge of a loading dock, with no pit needed. A short hinged plate and lip bridge the gap between dock and trailer, but it can only cover a small height difference above and below dock level, so it suits sites where trailer bed heights are consistent.
Where does this fit at a dock in Derry/Londonderry?
Companies running their own vehicles in Derry/Londonderry, where every trailer has a known bed height, are well placed to use edge-of-dock levellers instead of pit units. On older buildings in Derry/Londonderry where drains or services run close to the dock, avoiding a pit can make an edge-of-dock leveller the sensible route.
If trailer heights at a site in Derry/Londonderry vary widely, our survey will tell you plainly whether an edge-of-dock leveller can cope or a pit leveller is needed.
It starts with a free site survey in Derry/Londonderry, where we measure the openings, check the dock and talk through how the bay is used. You then receive a fixed written quote. Once you accept, we manage the job: specialist installation engineers carry out the work under our management, planned around your deliveries, and out-of-hours working can be arranged. At handover we test everything with you and leave the documentation.
How much height difference can an edge-of-dock leveller handle?
An edge-of-dock leveller can only handle a small height difference, typically in the region of 75 to 150 mm above and below dock level depending on the model. That is enough where trailers are consistent, but not where bed heights vary widely.
Typical UK docks are around 1,200 mm above yard level, while trailer bed heights can range from roughly 900 to 1,600 mm across rigid, curtain-sider, refrigerated, double-deck and container chassis. If your trailers sit outside the leveller's range, the plate becomes too steep to use safely.
- Good fit: dedicated fleets or regular suppliers with similar trailers.
- Poor fit: sites receiving everything from low rigids to high double-deck trailers.
Where trailer heights vary, a pit leveller such as a swing-lip dock leveller gives a much longer, gentler ramp. We record your trailer heights at survey to confirm which suits.
How is an edge-of-dock leveller fitted to an existing dock?
An edge-of-dock leveller is fixed to the front face or top edge of the dock from the yard side, and installation usually takes around half a day to a day per bay. No digging is involved.
- The dock face is inspected, and damaged concrete or worn edge steel is repaired or replaced first if needed.
- The leveller is positioned centrally on the door opening and bolted or welded in place.
- Bumpers are fitted or repositioned so trailers stop at the right distance from the plate.
- On hydraulic units, the power pack and controls are connected.
- The leveller is tested across its working range.
You will need to keep the yard approach to the bay clear, take the bay out of use and, for hydraulic units, provide a power supply near the door or ask us to include one. Because the work is outside, very wet or freezing weather can affect welding and fixing, so we keep the date flexible where we can.
The same published guide range applies across Northern Ireland; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Lighting inside trailers and at the dock face
- Bumper position and wear or damage on the dock face
- Asbestos register and any other site hazard information
- Wind exposure at the dock, which affects door and shelter choice
- Scope to convert ground-level doors into docks or add lift tables
- Traffic routes for vehicles and separation of pedestrians
Options to discuss
Mechanical edge-of-dock leveller
Lever-operated with spring assistance and no power supply needed. Suits low-volume bays and sites with consistent trailers where simplicity matters most.
Wider or heavy-duty plate
A wider plate or higher rating for larger forklifts, heavy loads or pallet trucks with a wide wheel track, specified after we look at your equipment.
Which rules apply in Northern Ireland?
Northern Ireland has its own system. Structural alterations at a site in Derry/Londonderry, such as a new opening or dock pit, may need building control approval from the council, and external structures such as loading houses or canopies can need planning permission through the council planning service. We check what applies at survey.
Questions about edge-of-dock levellers in Derry/Londonderry
Can you work alongside our main contractor on a new build in Derry/Londonderry?
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.
Will you deal with building control and planning for a project in Derry/Londonderry?
We check at survey whether the work is likely to need approval. Forming a new opening or dock pit may need Building Regulations approval, a building warrant or building control approval, depending on the nation, and external structures such as loading houses can need planning permission. Where approval is needed, we explain what is involved, work with your designer or agent, and build it into the programme.
Do you cover Derry/Londonderry for edge-of-dock levellers?
Yes. We take on edge-of-dock levellers for businesses in Derry/Londonderry and across County Londonderry. We survey the site, provide a fixed written quote and manage the installation, with specialist installation engineers working under our management. Visits are arranged in advance at a time that suits your operation, and the same single contact stays with the job through to handover.
Does the dock door still close with the leveller fitted?
Yes, in most layouts. Edge-of-dock levellers sit at the outer edge of the dock and store with the lip raised or folded, so the door closes behind them as normal. We check the clearance between the door, its bottom seal and the stored leveller at survey.
Can an edge-of-dock leveller be fitted to any dock?
Most docks can take one if the dock face or edge steel is sound enough to fix to. Damaged concrete or worn edge angles may need repair first. The more important question is whether your trailer heights fall within the leveller's small working range, which we check at survey.
