The detailed salient features:
• Single rocker arm, long wheelbase, and high strength working device and frame, large breakout force and traction, good stability. 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.
