Xuzhou Machinery Technology Co., Ltd., Seoul Branch Chen (xzkcr.com) is a professional "grass shears, disc trencher, fork grab" company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to participate in healthy competition in the market, so that the "general machinery, garden machinery, road series, in addition to snow Series" brand has a good reputation. We adhere to the "service first, customers first" principle, so that Seoul Branch Chen won the trust of customers congregation in dust removal equipment, and establish a good corporate image. Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! Excavator - Xuzhou Machinery Co., Ltd., Seoul Branch Chen originally excavator is manual, from the invention now has one hundred and thirty years, and during the struggle experienced by the steam-driven rotary excavator to electric drive and engine-driven rotary excavators, 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 snow machine, 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, the hydraulic excavator 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 swing speed refers to the no-load power shovel snow wing, stable average maximum speed of rotation can be achieved. This means that the definition of the rotation speed, neither is the starting time nor the rotational speed is the time of braking; that is, not accelerating or decelerating the rotational speed. For general excavation work for loaders Yang snow machines, this excavator when working in a range of 0 ° to 180 °, the rotary motor is accelerating or decelerating slip Yang snow machine, when to 270 ° to 360 ° range within, the rotation speed is stable. Therefore, in the actual excavation work, the rotation speed defined above is impractical. In other words, the need to accelerate the performance of the actual rotation represented rotary torque available / deceleration.
