How to check the various components of the crane?

As an important component of a crane, daily maintenance and inspection of crane accessories are crucial for the safe operation of the entire crane. However, there are so many components of crane accessories, and different components correspond to different methods and processes for checking faults. So how should we do it specifically? Below, the Shandong gantry crane manufacturer's editor will explain in detail:

1. Crane pulley. Check if the pulley is equipped with an anti slip groove device; Whether there are cracks, broken edges, excessive wear and tear on the pulley groove and rim, and whether the pulley rotates flexibly.

2. The braking device for lifting. It is necessary to check the setting of the brake, whether the type of brake meets the design requirements, and whether the brake rod and spring have defects such as fatigue deformation and cracks; Whether the wear of the pin shaft, spindle, brake wheel, and brake friction plate exceeds the standard, and whether the hydraulic brake leaks oil; Whether the brake clearance adjustment and braking capacity meet the requirements.

3. Crane drum assembly. Check for fatigue cracks, damages, etc. on the drum body and edges; Whether the wear of the rope groove and cylinder wall exceeds the standard; Can the height of the drum rim match the number of winding layers of the steel wire rope; Whether the working conditions of the rope guide and rope guide meet the requirements.

4. Crane reducer. Check for abnormal sounds such as severe metal friction, vibration, and shell radiation during the operation of the gearbox; Whether the shaft end is sealed properly and whether the fixing bolts are loose or damaged; Whether the selection of lubricating oil for the gearbox, the level of oil, the operation of the vertical gearbox lubricating oil pump, and the lubrication of the open gear transmission meet the requirements.
