Qinghai area of Dou Shan 9C series excavator through testing   

 In order to enter a market, the enterprise needs to improve the product of engineering machinery, continuously pass the high quality test and create the fine quality. In order to adapt to the regional environmental operations in the Chinese market, Dou Shan specially carried 9C series excavators to the high altitude area - Qinghai for testing.

Here is the high altitude and low oxygen environment that will allow people to start the new engine and the newly designed fuel system. Will there be winter black smoke, the burning of the problem? All are the factors to be considered.

Therefore, Doosan R & D personnel respectively in the summer of July and winter before October, for several types of Doosan 9C series of plateau quality test. The engine manufacturer, the fuel injection system engineer and the Dou Shan R & D Test Engineer are involved in it, and find the problem at any time and record the accuracy as reference data.

In order to make the Dou Shan excavator work normally in high altitude area, R & D personnel undergo rigorous testing and adopt a proper way to reduce excavator performance and reduce engine load, so as to improve working stability and get higher heat dissipation capability. The results show that the bucket Hill excavator is still strong at high altitude and low pressure area, and it can be applied freely to dig earth and gravel, no matter mine or earthwork.

The strict test standard of Dou mountain makes the excavator of Dou mountain higher and stronger. I believe that the product will be successful in the Chinese market.
