Inspect the anti-loose slot devices set by equipment manufacturers and correct any that do not meet requirements. Pay attention to issues during operation and strive to prevent such accidents. In our work, we should pay attention to the following aspects:

When the lifting device is lowering, the operator and the foreman must observe the tension of the steel wire rope to ensure that it does not slip onto the rim of the pulley.

When repairing hoisting equipment or a pulley block, a designated person must be present near the pulley block to monitor the wire rope while it is being tensioned, ensuring that the wire rope is in the groove.

3. Be cautious during operation to prevent sudden stops or rapid spinning of the lifting equipment. If such operations occur, ensure to inspect whether the groove of each pulley group is intact.

We must be cautious and meticulous about wire rope slipping off its track to minimize such incidents. If they do occur, we must detect and address them promptly to prevent the accident from escalating further.
