　　　Crane is a very useful lifting device. Its work mainly relies on the hooks in the lifting accessories to lift heavy objects, and then use the mechanical operation of the crane to achieve the purpose of work. But we know that there is a very important relationship between hooks and heavy objects, that is, the load-bearing capacity of hooks must be vigorously lifted, which is also the limitation of the use of hooks for lifting accessories.

　　The greater bearing capacity of the lifting hook during operation is called a dangerous point, which is the greater bearing capacity of the hook.

　　In most cases, in order to ensure the safe operation of lifting machinery, the actual bearing capacity of the hook will be measured and measured before use. The following is an explanation of the bearing capacity of the lifting hook.

　　When operating the crane, its safety of use is related to the safety of the lives and property of the staff, and the bearing capacity of the crane hook is a key indicator.

　　In order to ensure the safety and reliability of the crane during operation, many countries have formulated relevant technical standards or regulations for hooks to supervise the design, manufacturing and use of hooks.

　　As time goes by, the strength safety issues of lifting hooks mainly rely on theoretical calculations and finite element numerical verification. There is a lack of a good evaluation method for the actual bearing capacity of fixed-formed hooks, especially hooks with large rated lifting weight.

　　So, it is difficult to determine the actual bearing capacity and safety factor of such hooks at present.

　　The bearing capacity of the hook is related to the performance of the equipment and the safety of the operator, so its performance index needs to be tested for normal construction.
