the damage of Overhead Crane Load

the damage of Overhead Crane Load

the Overhead Crane Load work produces too much stress, can make the wire rope tensile damage, transmission part, motor burn down. Due to the braking force is insufficient, can not brake holding brake and cause major accidents. Overhead Crane Load work is harmful to Overhead crane structure, The typical example is to cause cracks on the main beam , the upper cover plate and the web plate to weld , and bring serious accident potential to the safety operation of the crane. Because the girder down warping, trolley track will accompany girder deformation. When the trolley runs from the middle to the two ends, it is not only to overcome the normal running resistance, but also to overcome the additional resistance to the climbing. In serious cases, the motor of the trolley running mechanism will be burned. In addition, the trolley will also appear "skid" phenomenon, slide, seriously affect the lifting operation. For double beam overhead crane, also can cause the trolley run "three legs", due to the horizontal side bending, and can make the small "gnawing rail" occur when running.

Overhead Crane Load

Overhead Crane Load work is more harmful to boom cranes and often results in serious accidents in which the boom and tower are broken. Due to the overload destroys the stability of the crane, but also will cause the machine overthrow the malignant accident.
