Q: What harm can be caused by overloading cranes?

The excessive gravitational force generated by the overloading operation of the crane can cause the wire rope to be broken, the transmission parts are damaged, and the motor is burned. Due to the insufficient braking force, the brake can not hold the brake and a major accident occurs. Overloading is very harmful to the crane structure. A typical example is that the main girder is deflection, the upper cover and the web are cracked, and desoldering, which brings serious accident hazards to the safe operation of the crane.

Due to the deflection of the main beam, the trolley track will deform along with the main beam. When the trolley drives from the middle of the span to both ends, not only the normal running resistance must be overcome, but also the additional resistance caused by the climbing. In severe cases, the motor of the trolley operating mechanism is burned. In addition, the trolley will also appear "skidding", and it will slip by itself, which will seriously affect the lifting operation. For double-beam cranes, the trolley will also cause "three-legged" operation, and due to the horizontal side bend, it will also cause "rail gnawing" during small operations.

Overloading is more harmful to jib cranes, and it often causes major accidents such as the breakage of the jib and the tower body. Overloading destroys the stability of the crane and can also cause a vicious accident of the whole machine overturning.
