9 Major Accidents Of Common Cranes

9 Major Accidents of Common Cranes
 

 

1. Crane loss accident:
 

 

2. Crane off-rope accident:
 

A de-rope accident refers to an accident of casualties and damage caused by the collapse of heavy objects from the bundled hoisting ropes.
 

 

3. Crane decoupling accident:
 

 

Top hook accidents mostly occur on bridge or gantry cranes, which are caused by the failure of the height limit. At the same time, it also happens from time to time on other types of cranes. The main reason is that the rigging anti-off device of the hook fails or the hoisting method is improper.
 

4. Crane broken rope accident:
 

 

 

 

Inclined hanging and cable pulling cause disordered ropes, crushing and cutting off steel wire ropes; steel wire ropes are broken due to long-term use and lack of maintenance, resulting in fatigue deformation, wear damage, etc., which meet or exceed the scrap standard and are still used.
 

 

5. Crane hook broken accident:
 

 

6. Crane crush accident:
 

 

 

7. Crane car fall accident:
 

 

8. Crane electric shock accident:
 

 

That is to say, the cause of electric shock is generally an electric shock accident caused by the electric machinery itself as a shock source (usually during the mechanical maintenance process), or because the crane operating at a height is too close to the exposed high-voltage transmission line and does not ensure sufficient safety. The crane itself is connected to electricity due to the distance, which in turn causes the operator or lifting worker to be directly injured by high-voltage electricity.
 

 

9. Crane body damage accident:
 

 

The accident occupies a very high proportion in self-propelled and tower cranes, and is one of the most common accidents.
