Maintenance, records and operator responsibilities
This domain tests the boundary between operating and maintaining a builder's lift, and the records that prove checks, defects and repairs were handled properly. The operator is a key reporter, not a substitute mechanic.
Maintenance and records
- Planned maintenance is by a competent person under the owner's or employer's system. It includes brakes, pinions, rollers, ties, limits, interlocks, electrical items and structural checks.
- Before maintenance, isolate and lock out/tag out. The maintenance person controls the keys/tags and confirms the hoist cannot be started.
- Records typically include the daily checklist, operator logbook, statutory certificates and thorough examination reports, maintenance and repair records, defect reports, and handover notes.
- Records must be available for inspection and kept accurate. Never sign for a check that was not done.
- The operator reports defects and may carry out only the checks and minor tasks they are trained and authorised to do.
Operator responsibilities
Use the hoist within its rating, protect the controls, keep the cage and landings clear, report damage or abnormal behaviour, and refuse to operate an unsafe hoist. Do not adjust the brake, bypass an interlock, alter the mast or change the control system.
Worked example
An operator finds oil leaking near the drive unit and a pinion tooth with visible wear. The hoist is still running. Decision: stop use, isolate and tag the hoist, report the defect to the supervisor, and record the observation in the logbook. Do not adjust the pinion or top up oil and continue. Maintenance by a competent person follows; if the repair affects a safety-critical part, the hoist is not returned to service until the required checks and any statutory examination are complete.
Traps that cost marks
- Adjusting the brake or limits to "save time" without authorisation.
- Signing a blank or incomplete daily checklist.
- Treating a verbal report as enough when the defect is safety-critical; record it.
- Assuming the operator may restart a hoist after a repair without the proper handback and checks.
