Electrical maintenance of electric single-girder cranes
In order to prolong the service life of the electrical equipment of the crane, the electrical equipment such as the contactor in the control box should be kept clean to prevent the occurrence of leakage breakdown and short circuit.
When using the hanging cable to conduct electricity, the corner rust and dirt on the guide rail of the trolley should be removed at any time to keep the traction pulley running normally. Check the track: mainly observe whether the track is straight, whether the pressure plate is firm, and whether there is any looseness.
