3. Operational Inspection:
- If possible, perform a functional test of the crane’s operations, including lifting and lowering loads, slewing, and trolley movement.
- Ensure that all controls and safety devices are working correctly.
4. Load Testing:
- Periodically, Inspecting a crane may require load testing to ensure their capacity.
- Consult the manufacturer’s guidelines or local regulations for load testing requirements and frequencies.
5. Wire Rope/Chain Inspection:
- Inspect wire ropes or chains for signs of wear, corrosion, kinks, or broken strands. If any issues are found, replace the affected parts immediately.
