With the adoption of a high-pressure direct injection spark ignition engine, each drop of fuel is burned efficiently, 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 standards.
2. Hydraulic system
The new-generation hydraulic components combined with the latest research achievements have higher efficiency, more accurate control, and reliability. Strong digging force and excellent operating efficiency are ensured.
1. The hydraulic control and electric control are dynamically integrated with the adoption of load self-adaptation control technology. The load follows the engine power in real-time, making full use of each drop of fuel. The fuel saves by 9% in E mode, and the efficiency increases by 22% in P mode.
2. The no-tail design with a small slewing radius is adopted. The left and right angle of deflection of the working device is respectively 75° and 50°. It can realize complex operations together with superstructure slewing to learn the digging process parallel with wall surface in narrow and small spaces through the cooperation of superstructure slewing to deal with various operating conditions efficiently.
3. The bulldozing deflection can increase operating methods in the narrow lanes, and the blade can be deflected by 25° respectively to the left and right.
4. One set of high-pressure quick change pipelines, two standby pipelines with adjustable flow, more selections of machines and tools are provided, and the adjustable flow control makes users' operation more comfortable.
Reliable and durable
1. Large-area tempered glasses with high strength are equipped on the cab, ensuring stability while improving vision. A floodlight is fitted on the cab's roof to provide accurate and safe operation at night.
2. Strengthened boom and arm, adjusted structure, and dispersive stress significantly improve service life. The new bucket type with decreased depth is a standard configuration, making unloading more convenient and efficient.
3. Its bearing performance is greatly improved with an X-frame chassis structure, reinforcing plate, and enlarged box cross-section.
The powers of the hydraulic pump and engine match intelligently, which determines working conditions automatically, ensures flow output, decreases engine speed ratio, and ensures the operating efficiency of the excavator.
Comfortable and safer
The fresh air system is equipped in a large view brand new cab, bringing better cooling and heating effects and a more comfortable operating environment. The family-style appearance and steady streamline make the whole machine more elegant and full of a sense of power.
Convenient maintenance and service
After the hood is opened, the maintenances of the diesel engine filter and oil filter are within reach; the inspection and refilling of oil and air conditioner refrigerant are incredibly convenient.
