For excavator product, energy conservation and emissions reduction, the concept of green environmental protection would have been introduced. First appeared in public view is a hybrid excavator. The first few years, however, because the technology is not very mature, so the market of hybrid excavator is not recognized by our clients. In recent years, because of hybrid technology upgrade, such products are starting to get more and more the favour of customers in the market. Hybrid excavator system is electric generator electric rotating, it replaces the hydraulic rotary hydraulic motor. The collection machine loss in the process of turning braking energy, and convert it into electricity. Renewable energy is stored in the super capacitor, and then the engine work in reducing fuel consumption. Japanese brand of komatsu and Hitachi done well in this aspect of market sales. Current excavator industry in our country there are dozens of host production enterprises, plus for excavator supporting enterprise, there are as many as hundreds of large and small. The personage inside course of study is generally believed that the future quite a long time, under the strong momentum of growth of national economy, including excavator, the whole construction machinery industry will be rapid development. The growth rate shows the excavator industry healthy and stable development of our country at the same time, the excavator industry task is also more heavy, energy saving and emission reduction for the excavator manufacturing enterprise technological innovation put forward higher requirements. Not only that, but as there were not enough strict import system, our country imported from abroad every year a large number of use fixed number of year long old excavator, these old excavator and serious are used in many parts of domestic excavator, energy consumption is very high, but also become a big pollution environment. Therefore excavator engineering industry is also need to constantly innovation, promote the green development of excavator industry
