Ac Power Yuchai's 73.5KW engine,super charged and intercooled,adopts BOSCH high pressure common rail system.Strong power, low fuel consumption,1.low noise, and meet environmental protection requirements.The high-strength damping shock absorber
can reduce vibration and noise, and effecti BE-160  protect the engine and oil pump.Imported dust removal oil pump has long life and high efficiency.

2. Humanized dashboard design,centralized display, simple and convenient operation.Concentrated pressure display,small vibration, accurate pressure measurement, improve the life of the pre
ssure gauge.The two-stage Fleetguard intake air filter assembly,equipped with a safety core,has a large flow rate and high filtration accuracy,which can effectively protect the engine for a long time and increase the service life of the engine.

3. The fuel is equipped with a large-capac-ity oil-water separator and high-efficiency three-stage precision filtration.lmported cast iron gear pump, high pre .ssure resistance, wear resistance and long service life.The newly designed hydraulic system,equipped with QTFLUID hydraulic valve, is centrally arranged, simple and reliable operation, and long service life.

4.EATON propulsion motor has small size, large torque and long life.
The newly designed rotary head, hydraulic four-speed 0-110rpm,low-speed high-torque,high-speed low-torque,adapt to various working conditions,and therotary spindle will never wear.Lengthened wear-resistant plate and horizontal rollers provide stable perfora
tion.The upper and lower guide rails are equipped with manganese steel flat irons,and the propelling beam operates smoothly.

5.It adopts excavator type plunger walking motor(JINGKEN),which has the characteristics of high efficiency, four wheeIs,high torque,and strong climbing ability.Widened engineering crawler, the whole machine walks steadily.It adopts the first-line brand roller chain after all, with high tensile strength.Equipped with waterproof and dustproof sprocket,long service life.
