What the visit covers in Harpenden
- Re-commissioning. Limits set, cycles tested and safety devices checked before handover.
- Matched drives. Motor torque, speed and mounting matched to the door's weight and size.
- Panel upgrades. Older panels can be replaced at the same time for better reliability and safety.
- Fault diagnosis. Diagnosis comes first, so you only pay for the parts the door actually needs.
- Force testing. Closing forces measured to BS EN 12453 where the door closes under power.
What this work can involve
- Diagnosing a stalling roller shutter to confirm whether the motor, a broken spring or the control panel is at fault.
- Replacing a motor with a slipping brake on a heavy shutter that creeps down from a part-open position.
- Fitting an equivalent chain-drive motor with adapter plates to a large sectional door whose original drive is discontinued.
Safety law for industrial doors in England
Industrial doors in Harpenden are covered by the same rules as the rest of Great Britain. On handover you should receive user instructions and, for a powered door, the conformity paperwork, because the installer is treated as the manufacturer when they assemble or motorise it. Afterwards, keeping the door in efficient working order is the occupier's job under the Workplace Regulations 1992 and PUWER 1998, which in practice means regular servicing and a written log.
Planning the work around your site
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.
