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 Argyll and Bute choose this?
New-build distribution sheds in Argyll and Bute 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 Argyll and Bute with frequent trailer swaps have more chances for an early drive-away, which is where a physical restraint adds real protection.
Restraint systems for sites in Argyll and Bute are surveyed, quoted and installed in the same way as anywhere else in the UK, with a fixed price set out in writing.
How does an installation in Argyll and Bute 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 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.

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 Argyll and Bute, 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
Is the site survey in Argyll and Bute 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.
What details do you need from us to quote for vehicle restraints?
To get started, send the site address in Argyll and Bute, the number of bays or openings, approximate sizes, and photos of the dock from inside and outside. Tell us what vehicles you load, what goods you handle and any temperature requirements. Drawings help on new builds. We then arrange the free survey and confirm the details before the written quote is issued.
Is a vehicle restraint a legal requirement?
Not in every case: HSE guidance (followed by HSENI in Northern Ireland) says there should be safeguards against drivers driving away too early, and a vehicle restraint is one of the measures it lists. Traffic lights and the person in charge keeping keys or paperwork are the others. Which measures you use should follow your risk assessment. In Northern Ireland the regulator is HSENI.
Do vehicle restraints work with all trailers?
Wheel-based restraints and sensor chocks work with most trailers, because they act on the rear wheel rather than on the back of the vehicle. Vehicles with unusual wheel positions or very small wheels need checking, so we look at the vehicles you receive during the survey.
