In the early days of new China, the W501, W502, W1001, W1002 and other types of mechanical single bucket excavator, which was founded by the former Soviet Union in twentieth Century 30 to 40s, began the production history of our country. Because of the need of national economic construction at that time, has set up more than and 10 excavator production plant. Began in 1967, China's independent research and development of hydraulic excavator. Early success of the development of the main products are Shanghai construction machinery factory WYl00, Guiyang mining machinery plant W4-60, Hefei mine machinery plant WY60 type excavator, etc.. Subsequently appeared in the Yangtze River excavator factory WYl60 type and Hangzhou heavy machinery plant, such as WY250 type excavator. They have made a very important step for the formation and development of hydraulic excavator industry in China.
By the end of 1980s, China's excavator production plant has more than and 30, the production of more than 40 kinds of models. Small and medium-sized hydraulic excavator has formed a series of bucket capacity 0.1 ~ 2.5 m3 in 12 grade, 20 kinds of models, but also the production of 0.5-4.Om3 and 10m3, 12m3 mechanical transmission of large mining excavator, excavator 1m3 tunnel, 4m3 long arm excavator, 1000m3 / h dumping machine, also developed the fighting capacity of O.25m3 the marine hydraulic excavator, bucket capacity of O.4m3, O.6m3, 0.8m3, amphibious excavator etc.. But generally speaking, China's excavator production of small, scattered, production technology and product quality and the international advanced level, there is a big gap.
