Dock traffic lights and interlocks, 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.

How does this suit sites in Urmston?

Food and chilled operations around Urmston with inflatable shelters often add interlocks so the shelter only inflates once a trailer is docked and restrained. Distribution centres near Urmston taking trailers from many different hauliers benefit from a signal every driver understands, regardless of language or familiarity with the site.

Sites around Urmston that run night shifts often find traffic lights easier for drivers to read than staff waving or knocking on the cab door.

Before anything is ordered, we visit your site in Urmston for a free survey and then send a written quote with a fixed price. From that point we manage the installation, coordinating delivery, access and any other trades. Fitting is done by specialist installation engineers engaged and managed by us, at times that suit your operation, including out of hours where agreed. You get a tested installation, a demonstration for your team and the manufacturer 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.

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.

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?

Workplace safety in England is regulated by HSE. For a loading bay in Urmston, that means doors meeting regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, equipment maintained under PUWER and suitable safeguards against vehicles driving away too early. We check what applies at survey and design the bay accordingly.

Questions about dock traffic lights and interlocks in Urmston

Will you deal with building control and planning for a project in Urmston?

We check at survey whether the work is likely to need approval. Forming a new opening or dock pit may need Building Regulations approval, a building warrant or building control approval, depending on the nation, and external structures such as loading houses can need planning permission. Where approval is needed, we explain what is involved, work with your designer or agent, and build it into the programme.

Can you work outside our normal operating hours in Urmston?

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 remove and dispose of the old equipment?

Yes, where it is part of the scope. When we replace doors, levellers, shelters or seals at a site in Urmston, removal and disposal of the old equipment can be included and is itemised in the quote, so it is clear what is covered. If anything should be kept, such as a frame or motor that is still serviceable, we agree that at survey.

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.

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.
