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 Milford Haven choose this?
Third-party hauliers visiting sites in Milford Haven may not know each site's procedures, so a restraint that holds the wheel removes reliance on every driver following instructions. A warehouse in Milford Haven that already uses traffic lights may want to add restraints so the door cannot open until the trailer is physically held in place.
Yards around Milford Haven 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.
Your loading bay stays our responsibility from the survey to the handover. In Milford Haven, the survey and written quote are free, and the quoted price is fixed for the agreed scope. Installation is carried out by specialist engineers working under our management, at times planned with you to protect your loading schedule. Out-of-hours work is available by arrangement. We finish by testing the equipment and handing over its documentation.
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.
What happens on site when a vehicle restraint is installed?
Installing a vehicle restraint takes the bay out of use while the rail or chock station is fixed, cabled and tested, but neighbouring bays can usually keep working.
- Set out: the restraint position is marked in line with the bay so it meets the rear wheels of the trailers you receive.
- Fixing: rail-mounted units are anchored into the concrete apron. If a new concrete base is needed, it must cure before the restraint is fitted.
- Cabling: ducts are cut or laid from the restraint to the dock wall, and the control box is fitted inside next to the door.
- Connection: the restraint is wired into the door, leveller and traffic light controls so the sequence works as designed.
- Commissioning: the system is tested with a trailer on the bay, and dock staff are shown how to engage and release it.
We ask you to release the bay for the agreed period, confirm an electrical supply point, provide a trailer for commissioning and tell us about any buried services in the yard.
The same published guide range applies across Wales; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Power supply at each bay, including three-phase availability
- Yard gradient and the slope of the approach to the dock
- Clear opening width and height for each door
- Bumper position and wear or damage on the dock face
- Dock height and the mix of trailers you load
- Control positions, isolators and any existing interlocks
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.
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.
Which rules apply in Wales?
Sites in Milford Haven follow the rules for Wales. Forming a new opening or dock pit may need Building Regulations approval, and loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey, so any approvals are understood before the programme is fixed.
Questions about vehicle restraints in Milford Haven
Do you cover Milford Haven for vehicle restraints?
Yes. We take on vehicle restraints for businesses in Milford Haven and across Dyfed. 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 you work alongside our main contractor on a new build in Milford Haven?
Yes. For new warehouses and fit-outs, we can supply and install the dock package as part of a wider project, working to the main contractor's programme, site rules and permits. We will need drawings, dock levels and the programme, and we coordinate pit details, power supplies and door openings with the relevant trades before installation begins.
Can you work outside our normal operating hours in Milford Haven?
Yes, by arrangement. Evening, night and weekend working can be planned so the installation causes as little disruption as possible to your loading schedule. Out-of-hours work can affect the price, so mention it at the survey and we will include it in the written quote. The agreed times are confirmed in the programme before the job starts.
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.
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.
