Do you know the scrapping standards for crane hooks?
The hook is an important equipment in the process of industrial processing by using hooks or rings to lift heavy objects and move and place them in the air. Its function is very large and can be said to be irreplaceable for lifting equipment. It is essential when lifting materials are needed in mines, metallurgy or ship docks.
It is precisely because of the importance of lifting hooks in industrial processing sites that before using hooks, we need to conduct safety inspections on the object. In addition, we also need to ensure that its performance does not have obvious defects: for example, the surface should be smooth and there must be no defects such as cracks, folds, acute angles, burrs, peeling, and overburning. If the following problems occur, they should be scrapped and welded and repaired:
1. Cracked on the surface of the lifting hook;
2. The wear of the injury section reaches 10% of the original size;
3. The opening degree increases by 15% compared to the original size;
3. The opening degree increases by 15% compared to the original size;
4. The hook body twist changes more than 10°;
5. The cross-section of the hook or the neck of the hook is plastically deformed;
6. The neck structure of the hook has undergone significant deformation;
7. The hook thread is severely corroded;
8. When the wear of the hook bushing reaches 50% of the original size, the bushing should be replaced;
9. When the wear of the hook spindle reaches 5% of the original size, the spindle should be changed.
The above questions are precautions for crane hooks if there are problems during use, I hope everyone can pay more attention to it.
