Dock traffic lights are red and green signals mounted outside and inside a loading bay to tell the driver and dock staff when it is safe to move or load. Interlocks are control links that stop equipment operating out of sequence, for example preventing the door opening until the trailer is restrained, or the leveller operating until the door is fully open.
Is this right for your site in Campbeltown?
Food and chilled operations around Campbeltown with inflatable shelters often add interlocks so the shelter only inflates once a trailer is docked and restrained. Loading docks in Campbeltown where drivers wait in their cabs for a hand signal can replace guesswork with a clear red and green light at every bay.
Sites around Campbeltown that run night shifts often find traffic lights easier for drivers to read than staff waving or knocking on the cab door.
It starts with a free site survey in Campbeltown, where we measure the openings, check the dock and talk through how the bay is used. You then receive a fixed written quote. Once you accept, we manage the job: specialist installation engineers carry out the work under our management, planned around your deliveries, and out-of-hours working can be arranged. At handover we test everything with you and leave the documentation.
Can traffic lights and interlocks be added to older loading bays?
Yes, traffic lights and interlocks can be added to most older loading bays, although some need new control panels before the interlocks can work.
- Manual doors: a door position switch can confirm the door is fully open or closed, which lets lights and leveller interlocks work even without a motor.
- Older powered doors and levellers: basic control boxes may not have connections for interlocks, so a combined bay panel can replace separate controls.
- Mixed equipment: doors and levellers from different suppliers can usually be brought under one interlock panel, so every bay works the same way.
Interlocks cannot make faulty equipment safe. If a door or leveller has a defect, it should be repaired before interlocks are added, and the survey will flag anything we find. Upgrading lights and interlocks at the same time as replacing a door or leveller is often the most economical moment to do it.
What happens on site when traffic lights and interlocks are fitted?
Fitting lights and interlocks is mainly electrical work, and each bay is out of use while its controls are connected and tested. Working bay by bay keeps the rest of the dock running.
- Fix the signals: the outside light is mounted on brackets at a height drivers can see, and the inside light beside the door.
- Run the cables: wiring is run in conduit or trunking between lights, sensors and control panels.
- Isolate and connect: the door and leveller supplies are isolated and locked off while the interlock wiring is connected, or a new bay panel is fitted.
- Test every sequence: each interlock is tested, including what happens if a step is attempted out of order.
- Brief staff: dock staff are shown the new sequence, and signs are fitted for drivers.
It helps if you can provide any electrical drawings for the dock, access to the distribution board, a person who can authorise isolations and an agreed order for releasing bays.
The same published guide range applies across Scotland; access, out-of-hours working and site conditions are confirmed at the free survey.
What do we check at the survey?
- Yard gradient and the slope of the approach to the dock
- Wall and steel structure for door, shelter and bumper fixings
- Asbestos register and any other site hazard information
- Condition of any existing leveller pit, kerb angles and pit drainage
- Clear opening width and height for each door
- Scope to convert ground-level doors into docks or add lift tables
Options to discuss
Trailer presence sensors
Sensors that detect a trailer on the bay, used to switch lights, enable the door or trigger an inflatable shelter where no restraint is fitted.
Standalone LED traffic lights
A red and green pair for each bay, one outside for the driver and one inside for dock staff, switched manually from a control beside the door.
Planning, building control and safety law in Scotland
Doors and dock equipment installed in Scotland may carry the UKCA or the CE mark, and we pass on the documentation for everything fitted in Campbeltown. Because building warrant and planning questions can affect the programme, we check what applies at survey and raise any approvals early rather than assuming none are needed.
For Campbeltown, installation work is planned in advance rather than on a routine round. The survey and quote are free; where we can, we group installation visits with other work nearby, and any travel and accommodation costs for fitting are set out clearly in the quote.
Questions about dock traffic lights and interlocks in Campbeltown
Will you deal with building control and planning for a project in Campbeltown?
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.
Do you cover Campbeltown for dock traffic lights and interlocks?
Yes. We take on dock traffic lights and interlocks for businesses in Campbeltown and across Argyll and Bute. 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.
How long does installation take at a site in Campbeltown?
It depends on the equipment, the number of bays, the condition of the dock and whether any building or electrical work is needed. We agree a programme with you after the survey, setting out which bays are out of use and when. Larger jobs are usually phased so that part of the dock stays open, and out-of-hours working can be arranged.
Do traffic lights and interlocks need maintenance?
Yes. Lights, sensors and interlocks should be checked at each planned service visit, including testing the full sequence and confirming that steps attempted out of order are blocked. As part of the dock equipment they fall under PUWER, which requires work equipment to be maintained in a safe condition.
Which way round do the inside and outside lights work?
The inside and outside lights always show opposite colours. While a trailer is being loaded, the outside light is red so the driver stays put and the inside light is green so staff can work. When loading is finished and the door is closed, the inside light turns red and the outside light turns green for the driver.
