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 matters for vehicle restraints in Haverhill?
Yards around Haverhill 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. New-build distribution sheds in Haverhill can have restraint rails and ducting planned into the yard slab from the start, which is simpler than cutting them in later.
A warehouse in Haverhill that already uses traffic lights may want to add restraints so the door cannot open until the trailer is physically held in place.
Here is what happens after you contact us about a site in Haverhill. We arrange a free survey, measure up and send a fixed written quote. If you go ahead, we manage the whole job, including ordering, delivery and coordination with your site team. Specialist installation engineers working under our management do the fitting, at times built around your loading schedule, with out-of-hours work by arrangement. Testing and handover documents close the job.
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.

What we look at on site
- Escape routes and pedestrian doors close to the bay
- Control positions, isolators and any existing interlocks
- Forklift and pallet truck loads crossing the leveller platform
- Wheel guide positions and yard markings for reversing vehicles
- How often each door cycles during a typical shift
- Headroom above the opening and which track type will suit it
Options to discuss
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.
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.
Regulations and approvals 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 Haverhill. 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 Haverhill
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 Haverhill, 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.
What warranty comes with new loading bay equipment?
New equipment comes with the manufacturer's warranty, which varies by product. Our workmanship terms are set out in writing in the quote for your Haverhill site, so you can see what is covered before you commit. Check the warranty terms for any servicing conditions, and we can quote for planned maintenance once the installation is complete.
Do you cover Haverhill for vehicle restraints?
Yes. We take on vehicle restraints for businesses in Haverhill and across Suffolk. We survey the site, provide a fixed written quote and manage the installation, with specialist installation engineers working under our management. Visits are arranged in advance at a time that suits your operation, and the same single contact stays with the job through to handover.
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.
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.
