The excessive stress caused by overloading operation of the Crane factory can cause the wire rope to be broken, the transmission parts are damaged, and the motor is burned. Due to insufficient braking force, the brake can not hold the brake and a major accident may occur. 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 the welding is unsold, which brings serious accident hazards to the safe operation of the crane.
Due to the deflection of the main girder of the crane, the trolley track will deform along with the main girder. 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 boom-type cranes, and it often causes major accidents such as the breakage of the boom and tower body. Because overloading destroys the stability of the crane, it can also cause a vicious accident of the whole machine overturning.
Here, Yuantai Hoisting reminds you that you must abide by the crane's operating specifications to avoid unnecessary things from happening. Reputation is more than anything, and we must avoid any factors that are not conducive to the machine.
