Crane accessories also need to undergo security checks

Crane accessories are the common names for crane components. What are the common crane accessories we see, and how can we conduct safety checks on lifting components? Let's take everyone to learn about it!
Drum: Whether there are fatigue cracks and fractures on the drum body and edges, whether the wear of the rope groove and drum wall exceeds the standard, whether the height of the drum edge matches the number of winding layers of the steel wire rope, and whether the working conditions of the rope guide and guide meet the requirements;
Reducer: whether there are abnormal sounds such as severe metal friction, vibration, and shell radiation during the operation of the reducer; Whether the shaft end is well sealed, and whether the fixing bolts are loose or defective; The selection of gearbox lubricating oil, oil level height, operation of vertical gearbox lubricating oil pump, and lubrication of open gear transmission meet the requirements.
Couplings: Check for defects, loose connections, and impact during operation of the coupling parts. Check for excessive wear on the coupling, pin shaft, pin shaft hole, and buffer rubber ring. Also, check if the coupling is concentric with the two connecting components.
Wheel: Check whether there are fatigue cracks on the tread and axle of the wheel, and whether the wear on the tread and axle exceeds the standard. Is there any rail gnawing phenomenon during operation. What is the cause of rail gnawing
Pulley: Does the pulley have 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
Wire rope: Check whether the specifications and models of the wire rope match the pulley drum according to the design requirements. Whether the steel wire rope fixing devices such as pressure plates, rope clamps, and wedges at the fixed end of the steel wire rope meet the requirements. Whether the wear, breakage, twisting, flattening, bending, strand breakage, corrosion, etc. of the steel wire rope exceed the standard.
These are all very important types of crane accessories. Before using the crane, we must conduct a safety check on these lifting accessories and not skip the security check due to inconvenience.
