Crawler Excavator,Excavator

Excavator adopts streamline design, with novel and pretty outline. It has large capacity air-condition in the cab and comfortable operating environment- low noise, low vibration. It also has reliable electronic monitoring instrument.

World-class Main Parts
1. Using high-quality imported CUMMINS Engine: water-cool, in line and direct injection, 4-cylinder and four-stroke cycle diesel engine. It has the features of good power, high reliability, high efficiency, low fuel consumption, low noise, low vibration and low emission. The engine meets the second phase off-road vehicle emission standards of Europe, the United States and Japan. It is a high efficient and environmental protection engine.
2. Excavator uses high-efficiency and energy-saving Japanese hydraulic pump: swash plate variable-displacement axial plunger pump, Japanese main control valve: ten-unit integral superimposed multi-way valve and pilot control valve. It can achieve the constant power regulation of hydraulic system, the confluence of boom and bucket rod, beeline walk, hydraulic pilot control and other functions. It can make full use of engine power to improve work efficiency and reduce operating strength of the drivers.
3. Adopting Japanese rotary motor + reducer: It integrates hydraulic motor, reducer, arrester, cushion valve, anti-reversal valve as one. So the machine works in a steady, safe and reliable way.
4. Adopting Japanese walking motor + reducer: It integrates hydraulic motor, reducer, arrester, cushion valve and straight walking valve as one. So it has the properties of compact structure, advanced performance, reliable quality and two-gear step-less speed drive function. It is suitable to walk on the rugged and uneven road.
5. Adopting high-quality hydraulic hose: convenient and reliable connection.
6. Excavator uses reliable Germany electrical instrument, simple interface digital display monitor and electronic throttle, which is reliable in quality and ingenious in disposal. So the driver can rapidly find and clear the trouble.
