When the wear of the stage electric hoist lifting hook reaches what level, it needs to be replaced
The lifting hook is a very important lifting component, commonly used for lifting or carrying heavy objects. In the process of lifting operations, work safety is very important.
After long-term use of the hook for a period of time, the hook may experience wear and tear. The wear and tear of the hook mainly refers to the wear and tear of the section, because in each lifting operation, the hook may be subjected to different forces for a long time, resulting in wear and tear. When the wear and tear surface of the hook is too much, it will affect the load-bearing capacity of the hook.
When the cross-sectional wear of the hook reaches 10% of the original, it is necessary to replace the hook in a timely manner. If it continues to be used or is not replaced in a timely manner, problems may occur.
The use of lifting hooks is crucial as it relates to the safety of operators and heavy objects. Therefore, strict safety operation instructions are required for use, and problems should be promptly resolved.
Standard for scrapping stage electric hoists
The hook should be scrapped if one of the following situations occurs:
① Cracks;
② Dangerous section wear reaches 10% of the original size;
③ The opening degree increases by 15% compared to the original size;
④ The twisting deformation of the hook body exceeds 10 °;
⑤ The dangerous section or neck of the hook undergoes plastic deformation;
⑥ The thread of the hook is corroded;
⑦ When the wear of the hook bushing reaches 50% of the original size, the bushing should be replaced;
⑧ When the wear of the hook spindle reaches 5% of the original size, the spindle should be replaced.
