Vehicle restraints, in short

A vehicle restraint is a device at a loading bay that physically holds a trailer against the dock until it is safe to leave. In the UK most systems act on the rear wheel, either as a powered wheel-based restraint or a sensor wheel chock. Restraints guard against early drive-away and trailer creep, and are usually interlocked with the door and dock traffic lights.

What should sites in Enfield Lock consider?

Third-party hauliers visiting sites in Enfield Lock may not know each site's procedures, so a restraint that holds the wheel removes reliance on every driver following instructions. A warehouse in Enfield Lock that already uses traffic lights may want to add restraints so the door cannot open until the trailer is physically held in place.

Multi-tenant logistics parks around Enfield Lock can benefit from restraints when several tenants share yard space and trailers from different fleets arrive throughout the day.

It starts with a free site survey in Enfield Lock, 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.

What is trailer creep and how does a restraint stop it?

Trailer creep is the gradual movement of a parked trailer away from the dock, caused by forklifts braking and accelerating as they drive on and off the trailer bed. Each movement pushes the trailer forward slightly, and over a full load the gap can grow.

Creep is more likely when:

the trailer is uncoupled from its tractor unit and resting on its landing legs;
air suspension or brakes have not been set correctly by the driver;
forklifts are heavy, fast or carrying dense loads such as drinks or building materials;
the yard falls slightly away from the building.

As the trailer moves, the leveller lip can lose its bearing on the trailer bed, and in the worst case the lip slips off with a forklift on it. A wheel-based restraint holds the wheel against the rail or chock, so the trailer cannot travel forward however many times a forklift drives on and off.

How does a vehicle restraint work with dock lights and interlocks?

A vehicle restraint is normally linked to the dock traffic lights and the door controls, so engaging the restraint is what allows loading to start.

A typical sequence looks like this:

The trailer reverses on to the bay with the outside light on green and the door closed.
The restraint engages the rear wheel. The outside light turns red for the driver and the inside light turns green for dock staff.
The door can now be opened, and the leveller can only operate once the door is fully open.
When loading is finished, the leveller is parked and the door closed before the restraint can release.
The restraint releases, the outside light turns green and the driver can leave.

The exact interlocks depend on your equipment and risk assessment. See dock traffic lights and interlocks for the options on signals and control logic.

Options to discuss

Hook restraint

A dock-mounted hook that catches the trailer's rear impact guard. Only suitable where your fleet has compatible rear guards, which we check carefully at survey.

Manual wheel-based restraint

The same rail-mounted principle with the restraint pushed into position by the operative. Lower cost than a powered unit, with a sensor to confirm engagement to the controls.

Planning, building control and safety law in England

Powered doors and dock equipment installed in England may carry the UKCA or the CE mark, and doors are covered by the product standard BS EN 13241. We hand over the relevant documentation for each item fitted in Enfield Lock. Planning and Building Regulations questions are never assumed either way: we check what applies at survey, so you know before work is booked.

Questions about vehicle restraints in Enfield Lock

Do you remove and dispose of the old equipment?

Yes, where it is part of the scope. When we replace doors, levellers, shelters or seals at a site in Enfield Lock, removal and disposal of the old equipment can be included and is itemised in the quote, so it is clear what is covered. If anything should be kept, such as a frame or motor that is still serviceable, we agree that at survey.

Is VAT included in your guide prices for vehicle restraints?

No. Our customers are businesses, so guide prices exclude VAT, which is added at the standard rate. The same guide range applies in Greater London as everywhere else: for vehicle restraints, it is £4,200 to £9,800 per bay, 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.

How do you price vehicle restraints for a site in Enfield Lock?

Guide budgets for supply and fit are £4,200 to £9,800 per bay, 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.

Will a vehicle restraint slow down loading?

Engaging a restraint adds only a short step to each docking, and once it is part of the interlock sequence it becomes routine for dock staff. Many sites find that a clear sequence actually reduces delays, because there is less confusion about when it is safe to open the door or release the driver.

Do vehicle restraints need servicing?

Yes. A restraint is work equipment under PUWER, so it must be maintained in a safe condition and inspected where wear could lead to danger. Servicing typically covers the rail and arm, sensors, controls and the interlock sequence with the door and lights.
