Single beam overhead crane overload operation will cause harm

Single beam overhead crane overload operation will cause harm 

Excessive stress generated by the overload operation of the crane can cause the wire rope to be broken, the transmission components to be damaged, and the motor to be burnt. Due to insufficient braking force, the brake cannot hold the brake and a major accident occurs. The overloading operation is very harmful to the crane structure. Typical examples are the main beam bending, the cracking and de-soldering of the upper cover and the web, which brings serious accidents to the crane.


Due to the downward deflection of the main beam, the trolley track will deform along with the main beam. When driving from the middle to the ends, the trolley not only overcomes the normal running resistance, but also overcomes the additional resistance caused by the climbing. In severe cases, the motor of the trolley operating mechanism was burned. In addition, the car will also appear "slip" phenomenon, rolling on its own, seriously affecting lifting operations. For the double-girder crane, it will also cause the "three legs" of the trolley to run. Due to the horizontal side bend, the phenomenon of "railing" will occur during small operation.


Overloading is more harmful to the jib crane, which often causes a major accident in which the boom and the tower body are broken. Because the overload damages the stability of the crane, it also causes a malignant accident of the whole machine overturning.


Here, the crane reminds you that you must follow the crane's operating specifications and avoid unnecessary things. The reputation is greater than everything. We must avoid any factors that are not conducive to the machine.
