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.

Why do sites in Thetford choose this?

New-build distribution sheds in Thetford can have restraint rails and ducting planned into the yard slab from the start, which is simpler than cutting them in later. Yards around Thetford that park uncoupled trailers at the dock can see trailers creep under forklift traffic, and a wheel-based restraint helps keep the leveller lip on the bed.

A warehouse in Thetford that already uses traffic lights may want to add restraints so the door cannot open until the trailer is physically held in place.

Our part of the job in Thetford is to survey, quote and manage; the fitting itself is done by specialist installation engineers working under our management. The survey and the written quote are free. Once the fixed price is accepted, we agree dates that work around your deliveries and shifts, including out-of-hours working where needed. Every installation is tested before handover, and you receive the documentation for each item fitted.

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.

Wheel-based or hook restraint: which suits UK trailers?

Wheel-based restraints and sensor wheel chocks suit most UK trailers, because they act on the rear wheel rather than on the back of the vehicle. Hook restraints, which catch the rear impact guard (sometimes called an ICC bar), are common elsewhere but suit fewer UK fleets.

Wheel-based restraint: a steel guide rail fixed to the yard, with an arm or chock that moves against the rear wheel, either powered or pushed into place by the operative. It works regardless of tail lifts or underrun guard design.
Sensor wheel chock: a heavy chock placed in front of the wheel, with a sensor or parking station that tells the dock controls it is in position. Lower cost and minimal groundwork, but it relies on someone placing it each time.
Hook restraint: mounted on the dock face and hooking the rear guard. UK and European trailers vary widely at the rear, and tail lifts often get in the way, so this type needs checking against your actual fleet.

Options to discuss

Trailer support stands

Stands placed under the front of an uncoupled semi-trailer to stop it dropping or tipping as forklifts drive on, used alongside a wheel restraint or chock.

Sensor wheel chock

A heavy-duty chock with a sensor or parking station that tells the dock controls when it is in place. Minimal groundwork and suited to retrofit on existing bays.

Planning, building control and safety law in England

Sites in Thetford 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 about vehicle restraints in Thetford

Will you deal with building control and planning for a project in Thetford?

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.

How do you price vehicle restraints for a site in Thetford?

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.

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 Norfolk 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.

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.

Can a vehicle restraint be fitted to an existing bay?

Yes, restraints are commonly retrofitted to existing bays. The main questions are whether the yard concrete in front of the bay is sound enough to anchor a rail, how cables will reach the dock controls, and whether the existing door and leveller panels can accept interlocks. Sensor chocks are often chosen where groundwork needs to be kept to a minimum.
