The driving wheel is composed of a walking motor, a walking deceleration mechanism and a sprocket . The hydraulic pressure from the autonomous pump can be rotated by the walking motor and decelerated by the walking deceleration mechanism.. Then the crawler chain rail is driven by the sprocket installed on the shell to realize the excavator’s walking.
