Options that matter on site
- Manual-to-electric. Hand-operated doors converted to power, with the paperwork a powered door needs.
- Inverter drives. Soft start and stop with faster opening for high-cycle doors.
- Activation options. Buttons, key switches, remotes, pull cords, loops, radar and access control.
- Matched motors. Direct, centre-mounted, chain-drive or tubular motors sized to the door.
- Traffic lights. Signals show drivers when the door is fully open and warn when it moves.
Jobs we can carry out
- Installing an airlock interlock between two high-speed doors so only one can be open at a time.
- Fitting induction loops and an inverter control panel so forklifts can open a busy internal door without stopping.
- Fitting a centre-mounted motor to a roller shutter where a side wall leaves no room at the barrel end.
Powered door rules that apply in Trowbridge
Trowbridge is in England, where powered industrial doors fall under Great Britain's health and safety law. Whoever makes a door powered — including converting a manual door — usually takes on the manufacturer's duties under the Supply of Machinery (Safety) Regulations 2008: risk assessment, technical file, conformity marking and a Declaration of Conformity. Once it is in use, the employer or occupier must keep it safe under the Workplace (Health, Safety and Welfare) Regulations 1992 and PUWER 1998.
Access, phasing and timing
Before work starts we send a method statement and risk assessment, confirm who on site will be our contact and agree where materials and access equipment will go. On shared industrial estates that can mean booking yard space with the landlord.

Frequently asked questions
Which activation would suit our Trowbridge site?
It depends on who uses the door. Buttons suit staff, remotes suit drivers, pull cords and loops suit forklifts, and radar suits mixed traffic. We look at your traffic on survey and recommend a set-up.
How long does a door automation job take in Trowbridge?
A straightforward conversion is usually completed and commissioned in a day. Loops, interlocks and traffic lights add time, and we plan the work so the door is out of use for as little time as possible.
Do you take responsibility for the conformity paperwork in Trowbridge?
Yes. When we convert a door to power, we carry out the risk assessment, test the door and issue the Declaration of Conformity and user instructions, as the person who has made it a machine.
