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 County Tyrone choose this?
Operators in County Tyrone 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 County Tyrone can benefit from restraints when several tenants share yard space and trailers from different fleets arrive throughout the day.
Yards around County Tyrone 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.
Any project involving vehicle restraints at a working site in County Tyrone takes planning. We survey free of charge, quote a fixed price in writing, and then agree a programme that keeps as much of the dock running as possible. Specialist installation engineers carry out the work under our management, out of hours if that suits you better. On completion we test each item, show your team how it operates and leave the documentation with you.
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.
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.

Questions
How long does installation take at a site in County Tyrone?
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.
How do you price vehicle restraints for a site in County Tyrone?
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.
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.
