Why can't the auxiliary hook of the overhead crane be pulled diagonally or crookedly?

[LeThomas]

Because when pulled diagonally or crookedly, the direction of force on the wire rope of the auxiliary hook's drum changes, which can easily damage the rope guide of the auxiliary hook and cause accidents. Therefore, it must not be pulled diagonally or crookedly. Overhead crane operation preparations: 1. Pass a physical examination before starting work: Overhead crane operators must pass a physical examination before starting work. Those with heart disease, high blood pressure, eye or ear diseases are not allowed to operate the crane. 2. Pass an exam before operation: Only after specialized training, passing an exam, and obtaining a certificate from the labor department can one operate the crane. 3. Wear protective equipment correctly: Before work, it is necessary to correctly wear labor protection equipment as required. 4. Complete shift handover records: Complete shift handover records, inquire about the equipment operation status from the previous shift, and only take over after inspection confirms it matches the records. 5. Check safety devices: Check the wire rope, machinery, electrical systems, brakes, limit switches, electric bells, lubrication, and the ten major safety devices, etc.
