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 Antrim choose this?
Third-party hauliers visiting sites in Antrim may not know each site's procedures, so a restraint that holds the wheel removes reliance on every driver following instructions. New-build distribution sheds in Antrim can have restraint rails and ducting planned into the yard slab from the start, which is simpler than cutting them in later.
Busy cross-dock and parcel operations in Antrim with frequent trailer swaps have more chances for an early drive-away, which is where a physical restraint adds real protection.
Here is what happens after you contact us about a site in Antrim. 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.
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.
The same published guide range applies across Northern Ireland; access, out-of-hours working and site conditions are confirmed at the free survey.
What do we check at the survey?
- Power supply at each bay, including three-phase availability
- How drivers are prevented from pulling away too early
- Temperature requirements for chilled, frozen or ambient goods
- Clear opening width and height for each door
- Asbestos register and any other site hazard information
- Traffic routes for vehicles and separation of pedestrians
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.
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.
Which rules apply in Northern Ireland?
Energy requirements for non-dwellings in Northern Ireland are set by Technical Booklet F2. For new or replacement loading bay doors in Antrim, we confirm the figure that applies to your project and check what applies at survey, rather than working to rules from elsewhere in the UK.
Questions about vehicle restraints in Antrim
Do you cover Antrim for vehicle restraints?
Yes. We take on vehicle restraints for businesses in Antrim and across County Antrim. 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.
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 Antrim 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.
Which building and safety rules apply to a site in Antrim?
It depends on which UK nation the site is in. England and Wales use Building Regulations approval, Scotland uses building warrants and Northern Ireland uses building control approval from the council. Workplace safety is regulated by HSE in Great Britain and HSENI in Northern Ireland, and energy rules differ between nations. For your site in Antrim, we check what applies at survey and design to it.
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.
