The hook is one of the main lifting accessories on lifting equipment and plays a very important role in lifting heavy objects. Normally, the crane will select the lifting weight of the hook based on the lifting capacity. This is to ensure that the crane will not be in danger due to excessive weight during the lifting process. Therefore, the use of hooks has very strict requirements. Let’s take a look at what are the requirements for the safe use of hooks, rings and other components?

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

2. When using the lifting ring, the force must be applied vertically and horizontal force is strictly prohibited;

3. The thread of the lifting eye must be tightened when rotating to prevent it from loosening and causing the hanging object 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 operations must have a smooth surface and must not have defects such as breaks, peelings, scratches, sharp angles, seams, and cracks;

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

7. The hook should be able to rotate flexibly; hooks and rings after repair welding are not allowed to be used;

8. The hook deflection angle should not exceed 10 degrees

9. When using a hook to connect a heavy object lifting ring, you must ensure that the position and force of the hook meet the requirements;
