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.
Where does this fit at a dock in Perth?
Operators in Perth reviewing their workplace transport risk assessment often look at restraints when key control alone has proved hard to enforce across shifts. Yards around Perth 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.
A warehouse in Perth that already uses traffic lights may want to add restraints so the door cannot open until the trailer is physically held in place.
How does an installation in Perth work? First, a free, no-obligation survey to measure up and understand the operation. Next, a fixed written quote. Then a programme agreed with you, so the work fits around deliveries, with out-of-hours slots if needed. The installation itself is carried out by specialist engineers who answer to us, and it finishes with testing, a walk-through for your staff and a handover pack.
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.
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.
The same published guide range applies across Scotland; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Lighting inside trailers and at the dock face
- Control positions, isolators and any existing interlocks
- Temperature requirements for chilled, frozen or ambient goods
- Traffic routes for vehicles and separation of pedestrians
- Forklift and pallet truck loads crossing the leveller platform
- Escape routes and pedestrian doors close to the bay
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.
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.
Regulations and approvals in Scotland
In Scotland, building work such as forming a new opening or a dock leveller pit may need a building warrant from the local authority before it starts. For sites in Perth, external structures such as loading houses or canopies may also need planning permission from the council. We check what applies at survey and factor any approvals into the programme.
Questions about vehicle restraints in Perth
Can you work alongside our main contractor on a new build in Perth?
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.
Is the site survey in Perth free?
Yes. For new installations, replacements, upgrades, conversions and complete bays, the site survey and written quote are free and come with no obligation. The survey lets us measure the openings, check the dock and structure, and understand how the bay is used, so the quote reflects your site. Repair and servicing visits are different: they are chargeable, with the price agreed before anyone attends.
Which building and safety rules apply to a site in Perth?
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 Perth, we check what applies at survey and design to it.
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.
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.
