Crane accessories refer to the general term for various components of cranes. What are the commonly used crane accessories in daily operations? And how to conduct proper safety inspections on these accessories? Below is a detailed explanation to help ensure operational safety.

Drum

Focus on checking whether the drum body and its edges have fatigue cracks or fractures; verify if the wear degree of the rope grooves and drum wall exceeds safety standards. The height of the drum edge must match the number of wire rope winding layers. Meanwhile, confirm that the rope guide and director are in normal working condition to meet operational requirements.

Reducer

During operation, pay attention to whether the reducer emits abnormal noises such as intense metal friction, vibration noise, or abnormal radiation sound from the housing. Check if the shaft end seal is intact and if the fixing bolts are loose or damaged. The selection of transmission oil, oil level height, operation of the lubricating oil pump for vertical reducers, and lubrication of open gear transmission devices must all comply with safety operation specifications.

Coupling

Observe whether the coupling has abnormalities such as component defects, loose connections, or impact vibration during operation. Inspect the wear degree of the coupling body, pin shafts, pin holes, and buffer rubber rings to avoid excessive wear affecting use. In addition, ensure that the coupling is concentric with the two connected components to guarantee stable transmission.

Wheels

Check if the wheel treads and axles have fatigue cracks and if the wear of treads and axles exceeds the limit. Pay attention to whether the wheels have rail gnawing during operation, and promptly identify the cause of rail gnawing to prevent fault escalation.

Pulley

Confirm that the pulley is equipped with an anti-slip groove device. Inspect the pulley groove and rim for cracks, edge breakage, or excessive wear, and test whether the pulley rotates flexibly without jamming.

Wire Rope

Verify that the specification and model of the wire rope match the design requirements of the pulley and drum. Check the fixing devices of the wire rope's fixed end, such as pressure plates, rope clamps, and wedges, to ensure proper installation and reliable performance. Focus on inspecting the wire rope for excessive wear, breakage, torsion, flattening, bending, strand breakage, corrosion, etc., and handle it immediately if the limit is exceeded.

The above are all core crane accessories, directly related to operational safety. Therefore, before using the crane each time, be sure to complete the safety inspection of these accessories one by one. Do not skip the inspection steps for convenience to eliminate potential safety hazards.
