The travel motor generally use high-speed motors plus planetary reducers or cycloidal pin reducers. The travel motor is equipped with a high-voltage automatic variable device. When the high-speed gear is engaged, the circuit is connected to the manual shift port to oil, pushing the shift valve to the left to make the motor become a small displacement; if the running resistance is increased, the oil pressure is raised to When the value is set, the oil pushes the shift valve to the right and the motor automatically changes to a large displacement low speed gear to increase the torque. Therefore, the motor can automatically change the gear as the walking resistance changes.


Reasons for the unilateral walking of the excavator:

1. The displacement of the single side pump is small or damaged.

2. The rotary joint is leaking.

3. The pilot pressure of walking on this side is not enough, and the foot valve is worn or the oil return is not smooth.

4. The main control valve is leaked or stuck.

5. The oil suction valve is faulty and the two switch joints under the foot valve are reversed.
