In 1999, the 400MW evaporative cooling hydro-generator technology of Lijiaxia Power Station with independent intellectual property rights in China was put into commercial operation. The temperature rise of the motor was low, the temperature distribution was even, the vibration of the unit was small, and it was in the best operation state. . The application of this technology has greatly promoted the process of developing, designing and manufacturing the highest level of hydro-generators in China, improving the economics and safety of large-scale motor operation in China and the operation level of the power industry, and obtained industrial and industry experts. The recognition of China's power industry and motor manufacturing industry is of great significance. The research on the electrical insulation, heat and mass transfer characteristics of the new non-polluting cooling medium, the cooling principle of the components in the motor and the rotating state The development of engineering structures, theoretical and engineering research is in an international leading position.

Mini Hydraulic Excavator is with compact design, and with low oil consumption, it is suitable to be used for small works,small projects, in garden, farmland, municipal works,vegetable greenhouse, digging trench It is with small engine, simple design, easy to maintain.

Advantages: 

1.Power system: advanced turbocharged engine exhaust enough power reserves, it is possible to maximize the power of the engine to achieve the perfect match, reducing power losses.

2.Hydraulic system: imported international brands hydraulic parts, power loss, fast action, complex motor coordination, high efficiency and energy saving, reliability and long service life.

3.Walking System: use heavier type front and rear drive axle, gearbox, providing higher carrying capacity.

4.Cab: new style cab, new interior design, vision, bright and spacious, humane front gear mechanism, adjustable suspension seat with a high-grade, silicone shock absorption, superior driving environment.

5.Cooling system: parallel cooling installation, installation and removal are easy to clean; it has very high cooling efficiency.
