The key parts of engineering machinery industry is the foundation and support of development and bottleneck, when construction machinery after a certain stage of development, research on high technology industry will be mainly gathered in the key parts of the engine, hydraulic transmission and control system, etc..

The dynamic performance of construction machinery is one of the most important indexes to measure the technical level of a product. It includes two parts: the dynamic performance of the diesel engine itself and the comprehensive performance of the power transmission of the whole engine. In addition to the continuous improvement of engine fuel injection system and reduce fuel consumption and low carbon emissions and other common technology, the state of low speed torque and power output, reserve performance matching, vibration and noise have specific requirements. At present, China's construction machinery products supporting the engine, fuel, Cummings, Weichai DEUTZ, pokings, Isuzu, Yanmar etc.. High end products, export equipment, large tonnage equipment and excavators almost all rely on foreign brands.

The transmission parts of construction machinery include double variable system, planetary reducer, drive axle and suspension system, slewing bearing, four wheel belt and so on. At present our country transmission engineering mechanical components research and development level, development means and the international advanced level is relatively backward in about 30 years, there are few domestic enterprises can bear the closed test means loading load spectrum, transmission gear accuracy and performance with the international advanced level gap is also large.
