1. Wipe the main hook clean;
2. Check all bolts and bolts to ensure that all opening pins are complete and open.
3. Check whether the pulley groove and flange wear is uniform, whether the wire rope matches the groove, whether the pulley is loose or swaying.
4. Ensure that the rotating part of the hook rotates freely and the clearance should not be too large. If it is difficult to rotate or feel stuck, it is necessary to check whether bearings, bushes are damaged or lubricated insufficiently.
5. Check the overload damage of the main hook.
