Description

technical field

[0001] The invention relates to the technical field of crane equipment, in particular to a protection device for a crane hook. Background technique

[0002] The crane hook is an appliance used to lift heavy objects. When the crane is hoisting, the heavy object is hung on the crane hook, and the lifting of the crane is used to drive the heavy object to move to the designated position. However, the existing crane The hook is usually not equipped with a protective device. When lifting heavy objects, it relies on its own weight to maintain the balance of the lifting. However, for large objects with an unstable center of gravity, it is difficult to control the center of gravity when lifting, which causes the center of gravity to change during the lifting process. The phase falls off, causing the crane hook to shake, which is likely to cause accidents.

[0003] When the hook is not in use, the hook is often put away and hung in the air. After a long period of wind...
