Scrap status of semi-enclosed hook groups
The result of the semi-closed hook group fall accident is both human and material. Therefore, we should strive to design, purchase and install and construct equipment in equipment selection, protection measures, factory construction, lifting process, working environment, regular inspections, etc. in accordance with the relevant national lifting machinery regulations and standards. Starting from the perspectives of people and objects, users should formulate rules and regulations and operating procedures for crane operation, maintenance and management.
At the same time, we should be clear that according to the national regulations on special equipment management, regular inspection and inspection of the performance of cranes (including lifting auxiliary equipment) is a necessary condition to ensure that the lifting reduces the operation of equipment.
If the following situations occur, the semi-closed hook group should be scrapped:
1. Cracked in the forged hook;
2. The wear of the dangerous section reaches 10% of the original size;
3. The opening degree increases by 15% compared to the original size. ;
4. Torsion-aligning deformation of hook body above 10;
5. Hazardous sections of semi-closed hook group or hook necks occur plastic deformation;
6. The threads of semi-closed hook group are corroded;
7. When the wear of the piece hook bushing reaches 50% of the original size, the bushing should be replaced;
8. When the wear of the piece hook mandrel reaches 5% of the original size, the mandrel should be replaced.
To sum up, it is an introduction to the semi-closed hook group, I hope it can help everyone.
