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.
Why do sites in Bangor choose this?
Loading docks in Bangor where drivers wait in their cabs for a hand signal can replace guesswork with a clear red and green light at every bay. Whether your unit in Bangor 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 Bangor with separate door and leveller controls can be brought into a proper sequence by adding interlocks that stop equipment working out of order.
Any project involving dock traffic lights and interlocks at a working site in Bangor takes planning. We survey free of charge, quote a fixed price in writing, and then agree a programme that keeps as much of the dock running as possible. Specialist installation engineers carry out the work under our management, out of hours if that suits you better. On completion we test each item, show your team how it operates and leave the documentation with you.
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 Northern Ireland; access, out-of-hours working and site conditions are confirmed at the free survey.
What we look at on site
- Dock height and the mix of trailers you load
- Asbestos register and any other site hazard information
- Temperature requirements for chilled, frozen or ambient goods
- Condition of any existing leveller pit, kerb angles and pit drainage
- Forklift and pallet truck loads crossing the leveller platform
- Lighting inside trailers and at the dock face
Options to discuss
Full bay interlock panel
A single control panel that runs the door, leveller, restraint and shelter in the correct sequence, with indicators showing which step is active or blocked.
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.
What do the rules in Northern Ireland mean for the work?
Energy requirements for non-dwellings in Northern Ireland are set by Technical Booklet F2. For new or replacement loading bay doors in Bangor, we confirm the figure that applies to your project and check what applies at survey, rather than working to rules from elsewhere in the UK.
Questions about dock traffic lights and interlocks in Bangor
How long does installation take at a site in Bangor?
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.
Can you work outside our normal operating hours in Bangor?
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.
How do you price dock traffic lights and interlocks for a site in Bangor?
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.
Will interlocks slow down my loading operation?
Interlocks add a fixed sequence, but each step takes only moments and staff soon get used to it. In practice many sites find the sequence saves time overall, because there are fewer arguments about when to open the door and less damage from levellers being raised into part-open doors.
Can interlocks be fitted to a manual loading bay door?
Yes. A door position switch fitted to a manual door can confirm when it is fully open or fully closed. That signal lets the traffic lights change automatically and stops the leveller being raised until the door is out of the way.
