1,The overall layout and the axle load distribution are more reasonable to achieve better traveling stability and the maximum traveling speed is up to 40km/h to realize faster site transfer speed.
2,The domestic leading hydraulic system distribution technology features high energy-saving and efficiency.
3,The highest breakout force on the loading end is leading the industry by 15%~20% compared with like models.
4,The advanced structure and hinge points on the digging end and the industry's largest rotating angle of the bucket ensure strong soil holding capacity.
