**1, adopt Xinchai turbocharging diesel engine, strong power, energy conservation, environmental protection, satisfies the requirement of high efficiency operation.
**2. the transmission, hydraulic pump, main valve, rotary motor, hydraulic cylinder, joystick control valve all adopt domestic famous brands
**3, full hydraulic load sensing steering system, small turning radius, flexible steering, hydraulic system equipped with oil radiator and back pressure protection device, ensure the machine heat balance.
**4, use heavy excavators drive axle, four-wheel drive, spiral bevel gear and wheel planetary wheel deceleration increasing twist, big load capacity, long service life.
**5, use four-wheel drum brake, the rear air tank, 18 times braking pressure strength ratio, safer and more reliable working
6. double oil cylinder vibration absorber control, optional to match with dozer blade and out trigger, remain in a stable condition during working and walking
7, cooperate with hercynian institute of Chinese Academy of Sciences "overall structure optimization scheme", verifies the stiffness and strength calculation, fatigue life forecast on the excavator, comprehensive finite element mechanics analysis, structure design optimization, ensure the security of the products use
7.1, workinge arm and bucket rod adopt large cross section box structure, high strength, to meet requirements of the heavy work
7.2, beams on both sides of the slewing platform use D word structure, can resist the external strong shock
7.3, standard with bucket, and can be fitted with hammer, wood grab, screw drill, etc. according to customer requirements.
8, with massive deepen heavy tire, front steering axle can swing around the center, have good traction performance and passing performance.
9, matched with adjustable direction, airline seats, joystick control distributing valve and working device, flexible and convenient manipulation
