- Single rocker arm, long wheelbase, and high strength working device and frame, large breakout force and traction, good stability. Short work cycle time. Superior integral performance. Applicable to heavy mining work conditions.
-Centralized articulated points on both front and rear frame, tracks of front and rear wheels superposition while steering, which improves the pass ability and effectively prolongs the tyre's service life; 
- The key articulated points adopt anti-dust structure, which prolongs the service life of pin axle;
- Equipped with water tank of large heat-transfer area, improving the heat balance in the diesel system, suitable for continuous work under tough work conditions;
-Add hydraulic oil radiator, improving the heat balance in the hydraulic system, suitable for continuous work under tough work conditions;
-The dual pump converging hydraulic technology, 16Mpa's system pressure, efficient and energy-saving, and strong power.
- Full hydraulic coaxial flow amplification steering system, ensuring convenient and flexible steering and reliability.
- Equipped with advanced Johnson maintenance-free battery, ensuring reliable and stable work.
