How to determine whether the hook of a hand chain hoist is scrapped
The hook is a type of sling and can also be used as an important accessory of the hand chain hoist. The degree of damage to the hook determines whether it needs to be scrapped, and there are certain criteria for judgment.
If the cross-section wear of the hook exceeds 10% of the nominal size, it needs to be scrapped;
Cracks appear on the surface of the hook;
Plastic deformation occurs in dangerous sections or necks;
The deformation of the hook mouth size increases by more than 15% of the nominal size;
Torsional deformation exceeds 10°.
