Dock traffic lights and interlocks in Tyne and Wear

In short

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 Tyne and Wear?

Food and chilled operations around Tyne and Wear with inflatable shelters often add interlocks so the shelter only inflates once a trailer is docked and restrained. Sites around Tyne and Wear that run night shifts often find traffic lights easier for drivers to read than staff waving or knocking on the cab door.

If a site in Tyne and Wear has had door panels damaged by levellers raised too early, a leveller-to-door interlock is a straightforward fix to consider.

The survey is free, the quote is written and the price is fixed: that is how every installation in Tyne and Wear begins. We then manage the work from start to finish. Fitting is carried out by specialist installers under our management, phased so the operation keeps moving, and nights or weekends can be booked by arrangement. On the final day we test the equipment with you and hand over the operating and maintenance information.

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.

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 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 Tyne and Wear 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.

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.

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.
