such as two motors are not burned, one of the motor has a problem, generally compare the temperature of the two motors, check the low temperature one.

A, the cause of the big car swing.

　　1, such as two motors are not burned, one of the motor has a problem, generally compare the temperature of the two motors, check the low temperature one.

　　2, the linkage shaft is broken or reducer box is bad.

　　3, the two motor models are different.

　　4, one side of the brake is bad.

　　5, the gap between the motor and the contactor mechanical teeth is too large resulting in the overhead crane in the anti-brake, start swinging and jumping phenomenon.

　　6, there is a motor resistance (rotor) wire broken or bad contact.

　　7, there is a motor carbon brush fire serious.

　　8, linkage console contact is not good.

　　9, the big wheel or motor bearings have problems.

　　10, the road track again, slipping.

　　11, big wheel side gnawing track.

　　12, bridge crane hand operation level is low.

　　Second, the big car open to the fast gear motor vibration hit cause.

　　1, fast gear of the two contactors one of them can not work.

　　2, there are two contacts can not contact.

　　3, some of the motor carbon brush burned or rotor broken wire.

　　4, the resistance gear line is poorly connected, but the swing and vibration to be relatively small.
