The Reasons of Accidents Happening in the Hoisting Machinery



 
 

In the daily performance of the hoisting machinery, the common accidents causing injuries include the objects falling off the hook, the broken ropes, the moving objects being lifted dropping, the lifting equipment going through the hoist or touching the high tension cable and so on. The reasons are various but the two main reasons are the operating factors and the equipment itself.
2)The improper lifting methods, causing the objects falling off the hook or shaking to injure people.
3)The operating instructions are not complied with, for example, overloading or people in the dangerous working environment.
The command is not correct and the behavior is not balance.
 
1)The hoisting devices do not work, for instance, the hook, grab, steel rope, netting gear and other things fall off to cause some damage.
2)The operating system or the safe device do not work to cause some accidents, for example, the brake failure causes the objects to attack and push one another.
3)The strength of the components is not enough such as the overturn of the tower crane, whose reason is that the overturning moment of the body of the tower crane exceeds its stabilizing moment.
4)The electrical damage causes the electric shock accidents.
5)The bridge crane walks out of its rail; the most common reason is that the phenomenon of biting the track make the fastener loose.
