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
