Steering

The steering clutch is tighten by pressured springs and separated hydraulically with oil-type, multi-powder-metal discs.

Brake

The brakes are oil, two-direction floating band with mechanism foot pedals, hydraulic boosted. The steering and braking can be actuated in one control.

Travel operation

The operation of transmission, steering and braking is controlled by single lever. Transmission, left and right steering and braking can be realized for three speeds forward and three speeds reverse by one handle . 

Final drive

The final drives are double reduction with spur gear and segment sprocket, which are sealed by duo-cone seal

Undercarriage system

The undercarriage is section steel welded track roller frame with diagonal brace. The track rollers, carrier rollers and front idlers have the same floating seals which are long-service life and seal well.
