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.

How does this suit sites in Potters Bar?

Operators in Potters Bar reviewing their workplace transport risk assessment often look at restraints when key control alone has proved hard to enforce across shifts. Multi-tenant logistics parks around Potters Bar can benefit from restraints when several tenants share yard space and trailers from different fleets arrive throughout the day.

Third-party hauliers visiting sites in Potters Bar may not know each site's procedures, so a restraint that holds the wheel removes reliance on every driver following instructions.

Keeping the dock running is usually the first concern, so we plan around it. After a free survey of your Potters Bar 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.

What happens on site when a vehicle restraint is installed?

Installing a vehicle restraint takes the bay out of use while the rail or chock station is fixed, cabled and tested, but neighbouring bays can usually keep working.

Set out: the restraint position is marked in line with the bay so it meets the rear wheels of the trailers you receive.
Fixing: rail-mounted units are anchored into the concrete apron. If a new concrete base is needed, it must cure before the restraint is fitted.
Cabling: ducts are cut or laid from the restraint to the dock wall, and the control box is fitted inside next to the door.
Connection: the restraint is wired into the door, leveller and traffic light controls so the sequence works as designed.
Commissioning: the system is tested with a trailer on the bay, and dock staff are shown how to engage and release it.

We ask you to release the bay for the agreed period, confirm an electrical supply point, provide a trailer for commissioning and tell us about any buried services in the yard.

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

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.

Automatic wheel-based restraint

A powered arm on a yard-mounted rail that locates against the rear wheel at the push of a button and signals the dock controls once the trailer is held.

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.

Questions about vehicle restraints in Potters Bar

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 Potters Bar, 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 Hertfordshire 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.

What details do you need from us to quote for vehicle restraints?

To get started, send the site address in Potters Bar, 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.

What happens if a powered restraint loses power?

Powered restraints are normally designed with a manual release so a trailer is not trapped on the bay if power is lost. Your site procedure should say who is allowed to use the release and what checks they make first. We explain the release method at handover.

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.
