| Rotation |
| It adopts the planetary retarder of axial piston motor and the rotary bearing is roller bearing. Due to the rotary buffer valve and the dual pressure-reducing valve, slowdown and stopping can
be done smoothly. Mechanical rotary disc brake. |

The undercarriage
|
|
Two-speed independent hydrostatic system. The compact axial motor improves performance. The output axis driven by hydraulic motor is connected with the planetary retarding unit and the track roller. All the hydraulic components are installed within the side frame.
The travel speed can be chosen through the switch dashboard and the travel mode is shown on the LCD monitor. The hydraulic disc shut-down brake is built in each motor.
