By the late 1980s, China's excavator production plant has more than 30 production models of more than 40 species. Medium and small hydraulic excavators has formed a series, bucket capacity 0.1 to 2.5 m3, 12 levels, 20 kinds of models, production of 0.5-4. Cubic meters as well as large-scale mining with 10 cubic meters, 12 cubic meters of mechanical transmission Single shovels, one cubic meter tunnel excavators, Lanzhou Used Wheel excavator, backhoe 4 cubic meters, imports of used wheeled excavator, 1000 m3 / h of dump machines, has also developed a hopper capacity 0.25 cubic meters of marine hydraulic excavators, bucket capacity of 0.4 m3, 0.6 m3, 0.8m3 amphibious excavator. But in general, used wheeled excavator market, Chinese excavator production volume is small, scattered, production processes and product quality compared with the international advanced level, used wheel excavators for sale, there is a big gap. The second generation excavator: With the widespread use of hydraulic technology, the excavator has been applied more scientific gear, hydraulic excavator instead of mechanical drive technology is a major leap forward. 1950 Germany's first hydraulic excavator was born. Mechanical drive is the second generation of hydraulic excavators. Xining Used Wheeled excavators, Kim Ho used excavators, used wheel excavators for sale by Shanghai Used Construction Machinery Co., Ltd. Jin Hao. Xining Used Wheeled excavators, Kim Ho used excavators, used wheel excavators for sale is Shanghai Jin Hao Used Construction Machinery Co.
