China's excavator production started late, from 1954 Fushun excavator factory production of the first bucket capacity of 1m and sup3;
In the early days of the founding of New China, China's excavator production history began with the mapping of W501.W502.W1001.W1002 and other types of mechanical single-bucket excavators modeled on the former Soviet Union from the 1930s to the 1940s. Because of the needs of the national economic construction at that time, more than ten excavator production plants have been set up. Since 1967, China has independently developed hydraulic excavators. Early development of successful products are mainly shanghai construction machinery factory WYl00 type, Guiyang mine machinery factory W4-60 type, Hefei mine machine factory WY60 type excavator. Then there are the WYl60 type of Yangtze River excavator factory and the WY250 excavator of Hangzhou heavy machinery factory. They have taken an extremely important step towards the formation and development of China's hydraulic excavator industry.
By the end of the 1980s, there were more than 30 excavator production plants in China, producing more than 40 models. Small and medium-sized hydraulic excavators have formed a series, doping capacity of 0.1 to 2.5 cubic meters and other 12 grades, more than 20 models, but also the production of 0.5-4 cubic meters and large-scale mining 10 cubic meters, 12 cubic meters of mechanical transmission single-pipe excavators, 1 cubic meter tunnel excavators, 4 cubic meters long-arm excavators, 1000 cubic meters / h of drainers, etc. , but also developed a capacity of 0.25 cubic meters of marine hydraulic excavators, bucket capacity of 0.4 cubic meters, 0.6 cubic meters, 0.8m sup3; But in general, China excavator production volume is small, scattered, production technology and product quality compared with the international advanced level, there is a big gap.
Since the reform and opening up, we have actively introduced, digested and absorbed advanced foreign technology to promote the development of China's excavator industry. Among them, Guiyang Mine Machinery Factory, Shanghai Construction Machinery Factory, Hefei Mining Machinery Factory, Yangtze River Excavator Factory, etc. respectively, introduced the German Liebherr company's A912.R942.A922.R922.R962.R972.R982 hydraulic excavator manufacturing technology. In the next few years, Hangzhou Heavy Machinery Factory introduced the H55 and H85 hydraulic excavator production technology of Demag, Germany, and Beijing Construction Machinery Factory introduced RH6 and MH6 hydraulic excavator manufacturing technology of Ogakai (0-K) company in Germany. At the same time, there are Shandong Bulldozer General Plant (its excavator production base changed its name to Shan Reconstruction Machine Co., Ltd., including STRONG and JCM two brands), Yellow River Engineering Machinery Factory, Jiangxi Changlin Machinery Factory, Shandong Linyi Engineering Machinery Factory, etc. jointly introduced the PC100, PC120 of Japan's Xiaosong Production Institute. PC200, PC220. PC300, PC400 hydraulic excavator (except engine) a full set of manufacturing technology. These factories through the introduction of several years of technology digestion, absorption, transplantation, so that domestic hydraulic excavator product performance indicators to the international level in the 1980s, production has also increased year by year. Due to the increasing and diversified domestic demand for hydraulic excavators, the adjustment of the product structure of large and medium-sized state-owned enterprises has affected some other machinery manufacturers to join the hydraulic excavator industry.
