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.
Where does this fit at a dock in Middlesbrough?
Older docks in Middlesbrough with separate door and leveller controls can be brought into a proper sequence by adding interlocks that stop equipment working out of order. If a site in Middlesbrough has had door panels damaged by levellers raised too early, a leveller-to-door interlock is a straightforward fix to consider.
Sites around Middlesbrough that run night shifts often find traffic lights easier for drivers to read than staff waving or knocking on the cab door.
If you are planning dock traffic lights and interlocks for a site in Middlesbrough, expect four stages. A free survey and fixed written quote come first. We then agree a programme with you, including any out-of-hours work. Specialist installation engineers carry out the installation under our management, with us as your single point of contact. Finally, the equipment is tested, your staff are shown how it works and everything is handed over with its documentation.
One feature of the freight network near Middlesbrough is worth a mention: Teesport, one of the UK's largest ports, sits at the mouth of the Tees. Busy or quiet, a dock needs equipment sized for the vehicles it receives.
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.
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 England; access, out-of-hours working and site conditions are confirmed at the free survey.
Survey checklist for your dock
- Wind exposure at the dock, which affects door and shelter choice
- Gaps around trailers where heated or chilled air escapes
- Control positions, isolators and any existing interlocks
- Working hours, shift patterns and windows for out-of-hours work
- Clear opening width and height for each door
- Access for deliveries, cranes or lifting equipment during installation
Options to discuss
Restraint interlock package
Door, lights and vehicle restraint tied together so the door only opens once the trailer is held and the restraint only releases when loading is finished.
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.
What do the rules in England mean for the work?
Sites in Middlesbrough fall under the rules for England. Structural changes such as forming a new opening or a dock leveller pit may need Building Regulations approval, and external structures such as loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey and build any approvals into the plan.
Questions about dock traffic lights and interlocks in Middlesbrough
What warranty comes with new loading bay equipment?
New equipment comes with the manufacturer's warranty, which varies by product. Our workmanship terms are set out in writing in the quote for your Middlesbrough site, so you can see what is covered before you commit. Check the warranty terms for any servicing conditions, and we can quote for planned maintenance once the installation is complete.
Do you cover Middlesbrough for dock traffic lights and interlocks?
Yes. We take on dock traffic lights and interlocks for businesses in Middlesbrough and across North Yorkshire. 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.
Can you work alongside our main contractor on a new build in Middlesbrough?
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.
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.
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.
