To extend the lifespan of cranes and enhance the safety of crane equipment, proper maintenance and repair are essential. How should the maintenance and repair of various crane components be carried out? How often should maintenance be performed?

All structural inspections and maintenance meet usage requirements; maintenance checks are conducted monthly.

Variable Mechanism: All structural inspections and maintenance meet usage requirements, with a maintenance inspection cycle of once a month.

Valve Mechanism: All structural inspections and maintenance meet usage requirements; maintenance checks are conducted monthly.

The rotary mechanism: all structural inspections and maintenance meet the usage requirements, with a maintenance inspection cycle of once a month.

Grab Bucket Mechanism: All structural inspections and maintenance meet operational requirements, with a maintenance inspection cycle of once a month.

Transmission Box: Check for oil leakage and ensure normal oil temperature. Verify that the running noise is normal, and inspect the high-speed shaft and gear mesh through the transmission box access port. Maintenance checks should be performed monthly.

Brake System: Inspection and maintenance of oil pumps and brake components (including replacing worn brake pads, adjusting brakes, and replacing worn parts), with a monthly maintenance and inspection cycle.

Safety Limit Device: Check all limit switches for functionality, and perform maintenance checks on a monthly basis.
