China excavator industry development course review and prospect A, China excavator industry development: If China construction machinery industry marked by the five sets of countries set up the first mechanical industry, from the formation, development to grow, to become the worlds engineering machinery power, has experienced a short more than 40 years, especially the reform and opening up 30 years, the engineering machinery is especially rapid development in our country. Began to be developed in our country, the development of hydraulic excavator product is in the 60 s of the last century, from 1967 to 1967, this decade there are a few factories in China to research and development of hydraulic excavator, through years of unremitting efforts, overcome difficulties one after another, finally have a small amount of several kinds of specifications of the hydraulic excavator product preliminary success, this to the hydraulic excavator industry in our country the formation of an important step. Have sprung up in the same time, more than a dozen, dozens of Chinas first generation of hydraulic excavators research and development personnel. With the development of national economy and the need of national economic development, the domestic excavator no matter from the quantity and quality is difficult to meet the needs of large-scale construction work. Earliest sortie excavator industry in China in the early 80 s a number of excavator company successively introduced the international comparison of advanced hydraulic excavator manufacturing technology. The factory through the years the introduction of technology digestion, absorption, transplantation, comprehensively improve the index of domestic hydraulic excavator product performance to a level of international in the early 80 s, the product output also increased year by year, as domestic long period does not provide the basis of high quality and high performance accessories, such as engine, hydraulic components, plus for
