During the using of overhead / gantry crane, mechanical parts, electrical control and hydraulic system would inevitable-ably have abrasion or damage. Reasons that cause same damage may not one-to-one correspond. Carefully analyze the fault, find out the real reasons and take corresponding measures to eliminate the fault. Thus, recover the technical performance of the fault point. The following are the common faults and solutions of overhead cranes:
