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.
Is this right for your site in Oadby?
Loading docks in Oadby where drivers wait in their cabs for a hand signal can replace guesswork with a clear red and green light at every bay. Food and chilled operations around Oadby with inflatable shelters often add interlocks so the shelter only inflates once a trailer is docked and restrained.
Distribution centres near Oadby taking trailers from many different hauliers benefit from a signal every driver understands, regardless of language or familiarity with the site.
It starts with a free site survey in Oadby, where we measure the openings, check the dock and talk through how the bay is used. You then receive a fixed written quote. Once you accept, we manage the job: specialist installation engineers carry out the work under our management, planned around your deliveries, and out-of-hours working can be arranged. At handover we test everything with you and leave the 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.
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.
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
- Drainage on recessed or sloping dock approaches
- How drivers are prevented from pulling away too early
- Temperature requirements for chilled, frozen or ambient goods
- Access for deliveries, cranes or lifting equipment during installation
- Wind exposure at the dock, which affects door and shelter choice
- Headroom above the opening and which track type will suit it
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.
Door-linked lights
Lights that change automatically with the door position, using a door switch or a signal from the door control panel, so the outside light turns red as the door opens.
What do the rules in England mean for the work?
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 Oadby. 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 Oadby
Can you work outside our normal operating hours in Oadby?
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.
Do you cover Oadby for dock traffic lights and interlocks?
Yes. We take on dock traffic lights and interlocks for businesses in Oadby and across Leicestershire. 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.
Is VAT included in your guide prices for dock traffic lights and interlocks?
No. Our customers are businesses, so guide prices exclude VAT, which is added at the standard rate. The same guide range applies in Leicestershire as everywhere else: for dock traffic lights and interlocks, it is £650 to £3,400 per bay, excluding VAT. It covers supply and fit for a typical installation. Your fixed written quote after the free survey shows the net price, the VAT and exactly what is included.
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.
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.
