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.
