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.
What matters for dock traffic lights and interlocks in Stornoway?
If a site in Stornoway has had door panels damaged by levellers raised too early, a leveller-to-door interlock is a straightforward fix to consider. Whether your unit in Stornoway has one dock or twenty, the survey looks at each bay's existing controls before we quote a fixed price in writing.
Older docks in Stornoway with separate door and leveller controls can be brought into a proper sequence by adding interlocks that stop equipment working out of order.
Here is what happens after you contact us about a site in Stornoway. We arrange a free survey, measure up and send a fixed written quote. If you go ahead, we manage the whole job, including ordering, delivery and coordination with your site team. Specialist installation engineers working under our management do the fitting, at times built around your loading schedule, with out-of-hours work by arrangement. Testing and handover documents close the job.
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.
How much do dock traffic lights and interlocks cost?
Dock traffic lights and interlocks typically cost £650 to £3,400 per bay, supplied and fitted, excluding VAT. A pair of manually switched LED signals sits at the lower end, while a full interlock panel linking door, leveller, restraint and shelter sits towards the top.
What moves the price:
- Level of control: standalone lights, door-linked lights or a full interlocked sequence.
- Existing control panels: modern door and leveller panels often accept interlocks directly; older panels may need replacing with a combined bay panel.
- Sensors: door position switches, trailer presence sensors and restraint signals each add parts and wiring.
- Cable runs: distances between lights, panels and the power supply.
- Number of bays and timing: repeat bays reduce the cost per bay, while out-of-hours working adds to it.
These are guide budgets. After a free site survey we send a written quote, and that quote is the fixed price. VAT is added at the standard rate.
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?
- Power supply at each bay, including three-phase availability
- Yard gradient and the slope of the approach to the dock
- Lighting inside trailers and at the dock face
- Scope to convert ground-level doors into docks or add lift tables
- Gaps around trailers where heated or chilled air escapes
- Asbestos register and any other site hazard information
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.
Which rules apply in Scotland?
HSE is the workplace safety regulator in Scotland. At a loading bay in Stornoway, doors need to satisfy regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, dock equipment must be kept safe under PUWER, and drivers must be prevented from pulling away too early. We check what applies at survey.
We cover Stornoway by arrangement. The survey and written quote stay free: for remote and island sites we often start from your photos, drawings and a video call, then confirm measurements on site. Travel and any accommodation needed for the installation are shown as separate lines in the fixed quote.
Questions about dock traffic lights and interlocks in Stornoway
Do you cover Stornoway for dock traffic lights and interlocks?
Yes. We take on dock traffic lights and interlocks for businesses in Stornoway and across Orkney, Shetland and the Western Isles. 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 do you price dock traffic lights and interlocks for a site in Stornoway?
Guide budgets for supply and fit are £650 to £3,400 per bay, excluding VAT. The figure moves with size, insulation, the operator, electrics, access, any pit or groundworks and out-of-hours working. Where levellers are involved, the guide assumes an existing, sound pit. After the free survey you receive a fixed written quote, and that is the price for the agreed scope.
Is the site survey in Stornoway 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.
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.
Can you add lights and interlocks across a whole dock in one project?
Yes. A whole-dock project is usually phased bay by bay so most doors stay in use, and every bay ends up on the same control standard. That consistency makes training easier for staff and drivers, and it simplifies servicing because every bay behaves in the same way.
