Currently used digging machine, the United States and Japan and other developed countries there is a construction machine identification system, the new machine is the second mobile phone or remanufactured equipment is also used Yuchai 85 excavators, through identification system can be tracked, while For the machine itself, age, performance and other parameters can also be clearly presented, so that the whole construction machinery industry sales become transparent. With industry data show that nearly 40 percent of construction machinery from the hydraulic system failure Used 200 excavators, 15% of the fault from the engine. With intelligent EFI technology, can significantly improve the utilization of engine power, reduce system power loss 35 small hydraulic digging machine used to make the power system and the load better match the required power and reduce the work intensity of the engine and hydraulic components, thereby increasing the reliability of the equipment in long-term use of the whole. 35 small second-hand excavator, used excavators Kim Ho (certified), second-hand digging machine provided by Shanghai Used Construction Machinery Co., Ltd.
