1. Power system,
With the adoption of high pressure direct injection spark ignition engine, each drop of fuel is sufficiently burned, which brings better fuel economy; More accurately controlled fuel injection time and lower noise, the technologies such as exhaust gas recirculation (EGR), diesel oxidation catalyst (DOC) and diesel particulate filter (DPF) make the engine compliant with Euro V emission standard.

2. Hydraulic system
The new-generation hydraulic components combined with latest research achievements have higher efficiency, more accurate control and higher reliability so that strong digging force and excellent operating efficiency are ensured.

1. the hydraulic control and electric are dynamically integrated with adoption of load self-adaptation technology, follows engine power in real time, making full use each drop fuel. fuel is saved by 9% e mode efficiency increased 22% p mode.

2. the no-tail design with small slewing radius is adopted, left and right angle of deflection working device respectively 75° 50°, it can realize complex operation together superstructure to digging parallel wall surface in narrow space through cooperation so as easily deal various operating conditions.

3. the bulldozing deflection can increase operating methods in narrow lanes, and blade be deflected by 25° respectively to left right.

4. one set of high pressure quick change pipeline, two sets standby pipelines with adjustable flow, more selections machines and tools are provided, the flow control make users’ operation comfortable.

1. large area tempered glasses with high strength are equipped on the cab, which ensures meanwhile improves vision, floodlight is roof of cab to ensure accurate and safe operation at night.

2. strengthened boom and arm, adjusted structure dispersive stress greatly improve service life. new type bucket with decreased depth is standard configuration, which makes unloading more convenient efficient.

3. with x-frame chassis structure, reinforcing plate and enlarged box cross section, its bearing performance is greatly improved.

The powers of hydraulic pump and engine match intelligently, which determines working condition automatically, ensures flow output, decreases speed ratio efficiency excavator.

Fresh air system is equipped in large view brand new cab, which brings better cooling and heating effects more comfortable operating environment.the family style appearance steady streamline make the whole machine elegant full of sense power.

After the hood is opened, maintenances of diesel engine filter and oil are within reach; inspection refilling air conditioner refrigerant extremely convenient.
