Development status of China's construction machinery fittings Market
Since 12th Five-Year, the equipment manufacturing industry China especially engineering machinery industry rapid development, the industry system constantly improved and significantly enhance the ability of technological innovation, improve the international status and influence; at the same time, the strength of China enterprises also continued to improve. At present, China has become the world's largest equipment manufacturing industry.
Su Zimeng, Secretary General of China Construction Machinery Industry Association, said that the construction machinery industry is a sunrise industry in china. The production concentration and access difficulty of the industry are relatively large, and the future construction machinery market will be developed to high-end and intelligent direction, and the operation of the industry will be more and more standardized. The construction machinery enterprises should pursue the endogenous growth and innovation development, and meet the opportunities and challenges of the future market with an international perspective. According to the forecast, in 2015, the international demand for the main products will reach 210 billion US dollars, and the export of China's construction machinery products will reach 26 billion US dollars, becoming the world's export country.
We are pleased with the vigorous development of construction machinery industry. And the development of the accessories industry closely related to the host is not very high, especially the key components such as hydraulic parts, transmission parts, control parts, engines and other key technologies are still controlled by foreign enterprises. Therefore, due to the constraints of these factors, the quality of construction machinery products in China can not be compared with Caterpillar, Komatsu, Liebherr, Volvo construction equipment and other products with the world's leading technology.
Taking the power components of construction machinery as an example, the dynamic performance of the machine is one of the most important indexes to measure the technical level of the product. It includes two parts: the dynamic performance of the diesel engine itself and the comprehensive performance of the power transmission system of the whole machine. In addition to continuously improving the fuel injection system and reducing fuel consumption and low carbon emissions, the construction machinery engine has the specific requirements for the torque reserve and power output mode, performance matching, vibration and noise at low speed. 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, excavators and so on almost all rely on foreign brands.
In the transmission part of engineering machinery field, current 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.
The above mentioned problems also exist in the absolute key parts of construction machinery hydraulic parts. Needless to say, hydraulic component is one of the key components of construction machinery products. It can not only reflect the whole machine operation efficiency, simple and comfortable operation, but also is the main fault source of the whole machine work. For a long time, in the high pressure and large flow hydraulic device, the domestic parts and components enterprises are difficult to meet the requirements of the host enterprise, which makes the imported hydraulic parts become the only choice, especially in the excavator products. Thus, China's construction machinery, especially excavator machinery in key hydraulic parts are subject to foreign manufacturers of product supply.
To sum up, in the construction machinery industry continued to accelerate development, actively promote the development of construction machinery parts industry, not only plays an important role in advancing China's construction machinery product quality, but also to further improve the overall level of China's industry.
