Strong structure
Heavy load for the rocky condition; the working device and front and rear frame feature thick board of high strength, reasonable distribution and strong carrying capacity. 
The large rock bucket with capacity of 3.0m³ is improved in terms of the work efficiency and adaptation. The bucket teeth adopt the structure of toothholder and sleeve. The cutting blade and bucket edge are equipped with protection device, featuring excellent abrasion resistance and shock resistance. 
The thickness of the front frame lug and baseboard is 70mm, and the thickness of the up and down articulated board is 30mm. The machine is superior among the products of same kind in terms of the structural strength and carrying capacity. 
Large distance between up and down articulated boards, and large maintenance space. Resolve the load horizontally and vertically efficiently. Easier to access, the machine has more carrying capacity and larger opening space. 
Each part passes the scientific analysis with professional stress analysis software to ensure that the reliability and carrying capacity of the structural parts could reach the design standard and meet the requirement of the tough condition. 
Excellent performance
The strong breakout force of 17 ton and strong traction of 17.5 ton ensure that the machine could adapt to various tough condition.  
Reliable operation: with the long wheelbase of 3300mm and long machine body of 8185mm, the machine is ahead in the industry in terms of the operation reliability. 
Quick action: the total time of three devices is only 10.3s, and the speed is 11.5 km/hour during the operation. 
Strong adaptation to the work site: centered design, small turning raidus. No speed difference between front and rear wheels. The tyre is not easily worn.
