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 Barnet choose this?
Multi-tenant logistics parks around Barnet can benefit from restraints when several tenants share yard space and trailers from different fleets arrive throughout the day. Restraint systems for sites in Barnet are surveyed, quoted and installed in the same way as anywhere else in the UK, with a fixed price set out in writing.
Operators in Barnet reviewing their workplace transport risk assessment often look at restraints when key control alone has proved hard to enforce across shifts.
Our part of the job in Barnet 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.
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.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Age and condition of the equipment already in place
- Power supply at each bay, including three-phase availability
- Control positions, isolators and any existing interlocks
- Headroom above the opening and which track type will suit it
- Scope to convert ground-level doors into docks or add lift tables
- Bumper position and wear or damage on the dock face
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.
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.
Which rules apply in England?
Workplace safety in England is regulated by HSE. For a loading bay in Barnet, that means doors meeting regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, equipment maintained under PUWER and suitable safeguards against vehicles driving away too early. We check what applies at survey and design the bay accordingly.
Questions about vehicle restraints in Barnet
Will you deal with building control and planning for a project in Barnet?
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.
Which building and safety rules apply to a site in Barnet?
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 Barnet, we check what applies at survey and design to it.
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 Barnet 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.
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.
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.
