Theory

The SWING motor is a key component of the excavator's slewing mechanism. It converts the oil pressure provided by the main pump into mechanical energy and inputs it to the reducer. Its working performance will directly affect the rotation speed, driving torque, and rotation of the entire machine. Parking and parking brakes are key to determining the productivity of the entire machine. After the excavator has been working for a long time, the swing motor often appears weak in rotation and unstable in rotation. At this time, it is necessary to replace the internal parts based on the test results.
