　　The crane can complete the air lifting of heavy objects, which is of great significance to some large-scale engineering construction. However, if a heavy object falls during use occurs during the equipment, it may cause serious personal casualties. So let's take a look at what factors may lead to the decoupling of the crane hook:

　　1. Hook falls off accident. When lifted heavy objects, lifting ropes or slings take off from the hook hook, the main reason is that the hook protection device is faulty or the lifting method is incorrect.

　　2. Rope breaking accident. This means that the lifting rope or wire rope breaks due to overload. The main reason is that the lifting limiter fails to roll and break the wire rope, or wear, narrowly-staggered and inactive lifting, and lack of maintenance.

　　3. Accident of breaking the hook. It refers to a heavy object fall accident caused by a break of the hook. The main reason is that the hook is broken and fall accidents due to the rough quality of the hook, the hook is worn for a long time, and it is still in use to meet the scrap standards, and it is frequently overloaded, which causes the hook to break and fall.

　　To sum up, the fall of crane hooks is mainly caused by three factors. Therefore, in the future use process, in order to minimize the incidence of crane hook decoupling, heavy objects falling from the air or mechanical failures and damage, when using crane hooks, we should pay attention to regular inspections, at least once every six months; the hooks are not allowed to hang suspenders or objects before the crane work begins.
