What are the maintenance and scrap standards for hook sets?
The hook set will suffer a certain amount of wear and tear during repeated lifting and wear. In order to prevent dangerous accidents, the hooks should be inspected every month according to the usage conditions. Once the hook is inflexible in rotation and plastic deformation, it should be stopped. Different hooks have different load limits, which are within the safety range. Therefore, overloading is strictly prohibited.
The hook used in the human-driven hoisting mechanism shall be tested with 1.5 times the rated load as the test load. Hooks used in power-driven hoisting mechanisms are tested with 2 times the rated load as the test load.
After the hook is removed from the inspection load, there should not be any obvious defects or deformations, and the increase in the opening should not exceed 0.25% of the original size.
Hooks that pass the inspection should be marked in the low-stress area of the hook, including rated lifting capacity, factory logo or name, inspection mark, production number, etc.
The fundamental purpose of setting scrapping standards and regular maintenance of hook groups are the same, both are to ensure safety, so relevant engineering operators must pay attention to them.
