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 Macclesfield?
Whether your unit in Macclesfield has one dock or twenty, the survey looks at each bay's existing controls before we quote a fixed price in writing. Sites around Macclesfield that run night shifts often find traffic lights easier for drivers to read than staff waving or knocking on the cab door.
Loading docks in Macclesfield where drivers wait in their cabs for a hand signal can replace guesswork with a clear red and green light at every bay.
Your loading bay stays our responsibility from the survey to the handover. In Macclesfield, the survey and written quote are free, and the quoted price is fixed for the agreed scope. Installation is carried out by specialist engineers working under our management, at times planned with you to protect your loading schedule. Out-of-hours work is available by arrangement. We finish by testing the equipment and handing over its documentation.
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.
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.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What we look at on site
- Condition of any existing leveller pit, kerb angles and pit drainage
- How often each door cycles during a typical shift
- Age and condition of the equipment already in place
- Clear opening width and height for each door
- Scope to convert ground-level doors into docks or add lift tables
- Temperature requirements for chilled, frozen or ambient goods
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.
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.
Regulations and approvals 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 Macclesfield. 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 Macclesfield
Can you work outside our normal operating hours in Macclesfield?
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.
Can you work alongside our main contractor on a new build in Macclesfield?
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.
Do you cover Macclesfield for dock traffic lights and interlocks?
Yes. We take on dock traffic lights and interlocks for businesses in Macclesfield and across Cheshire. 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 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.
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.
