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.
How does this suit sites in Wokingham?
New warehouses in Wokingham can have lights and interlocks wired in during the electrical fit-out, avoiding retrofit cabling and keeping every bay on one control standard. If a site in Wokingham has had door panels damaged by levellers raised too early, a leveller-to-door interlock is a straightforward fix to consider.
Distribution centres near Wokingham taking trailers from many different hauliers benefit from a signal every driver understands, regardless of language or familiarity with the site.
We keep the process simple for sites in Wokingham. A free survey tells us what the dock needs; a fixed written quote tells you what it will cost and what is included. We then organise the installation, with specialist engineers under our management and a programme agreed around your shifts. Night and weekend work is available by arrangement. Before we leave, the new equipment is tested, demonstrated and handed over with its documentation.
How do inside and outside dock traffic lights work together?
Inside and outside dock lights always show opposite colours: when the driver sees red, dock staff see green, and the other way round. Each light is aimed at a different person, so each one only ever gives one instruction.
- Outside light, facing the driver: red means stay on the bay because loading is in progress; green means the bay is clear to leave or to reverse on to.
- Inside light, facing dock staff: green means the trailer is in place and it is safe to open the door and load; red means do not open the door or enter the trailer.
Lights can be switched in three main ways:
- Manually, by a switch beside the door, relying on dock staff to change it at the right moment.
- By door position, so opening the door automatically turns the outside light red.
- By the restraint, so the light only changes when the trailer is physically held.
Which interlocks should a loading bay have?
The most useful loading bay interlocks stop the door opening until the trailer is in place or restrained, and stop the leveller operating until the door is fully open. Beyond that, the right set depends on the equipment fitted and your risk assessment.
- Door to restraint: the door cannot open until the restraint is engaged or a trailer is detected.
- Leveller to door: the leveller cannot be raised until the door is fully open, which prevents the lip hitting door panels.
- Door to leveller: the door cannot close until the leveller is back in its parked position.
- Restraint release: the restraint only releases once the door is closed and the leveller parked.
- Shelter to trailer: an inflatable shelter only inflates when a trailer is docked.
On a bay without a restraint, a trailer presence sensor can take its place in the door logic, although it confirms a trailer is there rather than holding it. Combining interlocks with vehicle restraints gives the strongest protection against drive-away.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Control positions, isolators and any existing interlocks
- Wheel guide positions and yard markings for reversing vehicles
- Dock height and the mix of trailers you load
- Bumper position and wear or damage on the dock face
- Temperature requirements for chilled, frozen or ambient goods
- How often each door cycles during a typical shift
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.
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.
Which rules apply in England?
Powered doors and dock equipment installed in England may carry the UKCA or the CE mark, and doors are covered by the product standard BS EN 13241. We hand over the relevant documentation for each item fitted in Wokingham. Planning and Building Regulations questions are never assumed either way: we check what applies at survey, so you know before work is booked.
Questions about dock traffic lights and interlocks in Wokingham
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 Wokingham 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.
What details do you need from us to quote for dock traffic lights and interlocks?
To get started, send the site address in Wokingham, the number of bays or openings, approximate sizes, and photos of the dock from inside and outside. Tell us what vehicles you load, what goods you handle and any temperature requirements. Drawings help on new builds. We then arrange the free survey and confirm the details before the written quote is issued.
Can you work outside our normal operating hours in Wokingham?
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.
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 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.
