Pre-operational inspections, daily checks, maintenance and defect reporting
Pre-operational checks
Before each shift, the operator must conduct a pre-operational inspection: check fluid levels, tyres, outriggers, wire ropes, hooks, safety devices (limit switches, alarms), and structural components for damage. Also check the logbook for recent maintenance and defects. Any defect affecting safety must be reported and the crane not operated until rectified.
Maintenance and defect reporting
Regular maintenance as per manufacturer's schedule is required. Defects must be recorded in the logbook and reported to the supervisor. If a defect is found during operation, stop work, lower the load safely, and report. Never attempt to repair unless competent.
Traps in questions
A trap is assuming pre-operational checks are optional if the crane was checked yesterday. They are required daily. Another trap is operating with a minor defect; some defects (e.g., broken wire strand) are critical. Also, the operator should not perform maintenance beyond their competence.
Worked example / rule of thumb
Rule: If in doubt, tag out and report. Example: If a wire rope has broken wires exceeding the manufacturer's limit, remove from service.
