On the one hand in the stimulation of national policy, the domestic construction machinery market threshold gradually, the whole construction machinery industry structure contention also by the economic and durable products continuously adjusted toward intelligent environmental protection. Major construction machinery enterprises have also increased investment in technical innovation and new efforts to promote construction machinery manufacturers agreed action also means that the industry transition to a green, smart, "energy saving, environmental protection" has been infiltrated into the industry as a whole in. On the other hand, the domestic users of the mining machinery quality requirements are high, especially for product efficiency, fuel consumption, maintenance, salvage and other indicators are very concerned about. Doosan Infracore related to this high level stressed excavator industry generally use EFI engine direct injection engine to replace the original purpose is not simply to improve fuel efficiency to reduce fuel consumption so simple, hand digging machines, EFI engine is the reason why the industry recognition the industry's future, 15 second-hand digging machine, its significance lies more central around EFI technology with a range of intelligent control technology to be applied, only the intelligent control of fuel injection is the key to cost reduction achieved. Insiders said that second-hand excavator Sunward 60, China's energy-saving construction machinery industry will face important opportunities. In recent years, launched a series of new products, energy saving and environmental protection has become an important strategic development direction of construction machinery enterprises. Whether it is from the reduction of environmental burden, or break the external barriers and other considerations, energy saving and environmental protection of the road will become the main trend of construction machinery development. 60 Used excavator price | Kim Ho used excavators (certified) | Used excavator provided by Shanghai Used Construction Machinery Co., Ltd.
