The maintenance of main electrical equipment of suspension crane is described as follows:
1. In order to increase the service life of the electrical equipment of the crane, the electrical equipment should be kept normal: control) clean the contactor in the box to prevent electric injury and short circuit (the current is dead and directly connected to the power supply).
2. When conducting electricity with hanging cable, the rust and dirt on the corner of TTW guide rail shall be cleaned at any time to keep the traction pulley running normally. Check the track: mainly observe whether the track is straight, whether the pressing plate is firm and whether it is loose. If you find a track while the car is moving, you should try to correct the track or adjust the wheels.
