Hook is one of the main lifting accessories on lifting equipment and plays a very important role in lifting heavy objects. Generally speaking, the lifting opportunity selects the lifting weight of the hook according to the lifting weight. This is to ensure that the heavy objects will not cause danger to the crane due to excessive weight during the lifting process. Therefore, the use of the hook has very strict requirements. Let’s learn about the safe use of hooks, rings and other components?

1. The positioning bolts, opening pins, and nuts above the thrust bearing of the hook are well tightened and the connection is reliable;

2. When using the lifting ring, it must be subjected to vertical force, and it is strictly forbidden to apply to horizontal force;

3. The lifting ring thread must be tightened when rotating to prevent loosening and causing the lifting to fall off;

4. When using two lifting rings to work at the same time, the angle between the two lifting rings shall not be greater than 90 degrees.

5. The hooks and rings used in lifting and hoisting operations must have smooth surfaces and must not have defects such as breaks, peeling, marks, sharp angles, seams and cracks;

6. Hooks and rings are not allowed to be used overload;

7. The hook should be flexible in rotation; hooks and rings after rewelding are not allowed;

8. The hook slant angle should not exceed 10 degrees;

9. When using a hook to connect to a heavy object lifting ring, it is necessary to ensure that the position and force of the hook meet the requirements.
