Lifting hook components require regular safety inspections
The lifting hook is an important lifting and load-bearing device for electric hoists, and its quality directly affects the progress of operations. In recent years, accidents of sudden breakage of the hook have occurred frequently. Therefore, it is necessary to strengthen the analysis of the causes of hook breakage and the supervision of the hook.
1. Perform non-destructive testing on areas with concentrated stress on the surface of the workpiece. If cracks are found, immediately stop using and replace the hook with a new one.
2. Regularly check the wear or corrosion of the dangerous section of the hook. When the actual size is less than 95% of the original size, the hook should be replaced with a new one.
3. When the torsion of the hook body exceeds 10 °, a new hook should be replaced.
4. When the opening deformation of the hook reaches 15% of the original size, a new hook should be replaced.
5. Defects on the hook are not allowed to be repaired by welding.
6. The handle of the dangerous section or hook must not have plastic deformation.
The lifting hook is a vulnerable part of the electric hoist, and once a fracture or fall accident occurs, it can easily lead to major personal and equipment accidents. Therefore, it is necessary to conduct regular safety checks.
