Release Date: 2022-03-07 09:26:29 Visits: 476

As one of the auxiliary spreaders, the crane hook is often used on various types of hoisting equipment. The subsequent problem is that the hook is improperly used and maintained, causing large and small safety accidents to occur from time to time. Among them, the lack of regular inspection, effective monitoring and management is an important reason for lifting casualties. In addition to corresponding training for employees, effective management standards should also be formulated to ensure safety. The following is an introduction to the hook management of the crane. Orderly management can provide a reliable basis for efficient production.

 1. Management of hooks
The hooks for driving are given specific numbers by the user department according to their lifting weight, and are managed according to the numbers. The specific method is "hook lifting weight - serial number", for example: 16t hook, the numbers are 16-1, 16-2, 16-3, etc. With the number, it is convenient to keep records for the maintenance and management of each hook. There is a reliable data source for the status of the registered hooks, and the management and supervision personnel can also know what to do.
According to the actual needs of the model and model, with the approval of the technical information department, the user department can appropriately configure the spare hook assembly. In addition, the spare hook should be kept clean, and if rust is found, try to remove the rust.

Second, the use of the driving hook
1. When lifting the load, the load should be in the middle of the hook seat of the hook.
2. The lifting should be as stable as possible to avoid impact load.
3. The surface of the hook should be kept clean, without peeling, sharp angles, burrs, cracks, etc.
         
3. Scrap standard of hook (check)
The hook should be scrapped if one of the following conditions occurs (defects on the hook should not be repaired):
1. The opening of the hook exceeds the nominal size by 15%;
2. The hook is twisted and deformed more than 10 degrees;
3. The wear of the hook seat of the hook exceeds 10% of the nominal size;
4. Plastic deformation of the hook neck or dangerous section;
5. Cracks and cracks appear on the surface of the hook.

The hook is a very important accessory on the crane. Under normal circumstances, the crane will make a reasonable choice for the lifting equipment according to its own situation. Regular inspection and inspection of the safety performance of cranes (including hoisting aids) is one of the necessary conditions to ensure the safe operation of hoisting equipment and reduce the occurrence of accidents caused by falling objects from crane hooks. Longhui Crane has always insisted on reducing the factors that cause safety accidents from the details, and preventing problems before they happen is the real and effective safety awareness!
