Standards for hook safety inspection
Hook is an important lifting device in lifting equipment. Due to the long-term lifting of heavy objects, this has aggravated its loss. We need to make frequent safety suggestions to ensure the safety of construction.
1. The hook used for the lifting mechanism driven by humans is tested with 1.5 times the rated load as the inspection load.
2. The hook used for the lifting mechanism driven by power is tested with 2 times the rated load as the inspection load.
3. After the hook removes the inspection load, there should be no obvious defects or deformations, and the increase in opening degree should not exceed 0.25% of the original size.
4. The hook that passes the inspection should print the mark in the low-stress area of the hook, including the rated lifting weight, factory mark or factory name, inspection mark, production number, etc.
