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.
Is this right for your site in Johnstone?
Tenants of leased warehouses in Johnstone who cannot cut into the slab may find an edge-of-dock leveller the most workable way to improve loading. If trailer heights at a site in Johnstone vary widely, our survey will tell you plainly whether an edge-of-dock leveller can cope or a pit leveller is needed.
Wholesalers and trade suppliers in Johnstone adding a second loading position can often do so economically with an edge-of-dock unit.
Keeping the dock running is usually the first concern, so we plan around it. After a free survey of your Johnstone site and a written quote at a fixed price, we agree when each bay can be released and whether any work should happen out of hours. Specialist installation engineers working under our management then fit the equipment, and we test it and hand over the documentation before the bay goes back into use.
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.
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.
The same published guide range applies across Scotland; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Condition of any existing leveller pit, kerb angles and pit drainage
- Headroom above the opening and which track type will suit it
- Control positions, isolators and any existing interlocks
- Access for deliveries, cranes or lifting equipment during installation
- How drivers are prevented from pulling away too early
- Dock height and the mix of trailers you load
Options to discuss
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.
Hydraulic edge-of-dock leveller
Push-button operation with a compact power pack, easier for frequent use and able to be interlocked with dock doors and traffic lights.
Regulations and approvals in Scotland
In Scotland, building work such as forming a new opening or a dock leveller pit may need a building warrant from the local authority before it starts. For sites in Johnstone, external structures such as loading houses or canopies may also need planning permission from the council. We check what applies at survey and factor any approvals into the programme.
Questions about edge-of-dock levellers in Johnstone
How long does installation take at a site in Johnstone?
It depends on the equipment, the number of bays, the condition of the dock and whether any building or electrical work is needed. We agree a programme with you after the survey, setting out which bays are out of use and when. Larger jobs are usually phased so that part of the dock stays open, and out-of-hours working can be arranged.
Can you work alongside our main contractor on a new build in Johnstone?
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.
Is VAT included in your guide prices for edge-of-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 Renfrewshire and Inverclyde as everywhere else: for edge-of-dock levellers, it is £1,800 to £4,400 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.
Can edge-of-dock levellers be used with vans?
Usually not. Edge-of-dock levellers are designed for trailers whose beds sit close to dock height, and many vans sit well below a typical dock, beyond the leveller's range. A lift table or a ground-level door is normally the better way to handle vans.
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.
