Excavator - Xuzhou Machinery Co., Ltd., Seoul Branch Chen initially manually powerful excavator is throwing snow machines, from discovery to now has one hundred and thirty years, and during the struggle experienced by the steam-driven rotary excavator to electric drive and internal combustion engine driven rotary excavator, hydraulic integration technology applications automatic hydraulic excavator gradual development process. First hydraulic excavator Poclain invented by the French factory f success. Since the application of hydraulic technology, the 1940s had on a tractor equipped with a hydraulic excavator backhoe hanging. 1951, the first fully hydraulic backhoe by in France Poclain (Poclain) factory launched, resulting in the development of the art of creating a new space excavator. 20 early and mid-1950s have developed a trailer full swing hydraulic excavators and crawler hydraulic excavator. The initial trial is the use of a hydraulic excavator hydraulic technology aircraft and machine tools, the lack of suitable for a variety of conditions excavator hydraulic components, manufacturing quality is not stable enough, parts are not complete. From the 1960s slip Yang snow machines, hydraulic excavators into the promotion and flourishing stage, countries and varieties increased rapidly excavator factory, production soared. Between 1968-1970, a hydraulic excavator production accounted for 83% of total production of excavators, now close to 100%. Excavator - Xuzhou Machinery Co., Ltd., Seoul Branch Chen operating weight is excavators three important parameters (engine power brush snow blower, bucket capacity, operating weight) weight determines the level of operating excavators, mining decision cap machine digging force. Digging force ≦ m 'working weight m: adhesion coefficient between the ground and the crawler digging force exceeds this limit if, in the case of a backhoe and excavator will slip, and was pulled forward, which is very dangerous. In case shovel, excavator will slip backwards. Snow machines, Branch Chen Lear, XCMG Snow Blower provided by Xuzhou Machinery Co., Ltd., Seoul Branch Chen.
