As used construction machinery, and compare the new machine there is an infinite distance. Generally medium used excavators, the new machines within a few years there will not be much doubt, even if there is a doubt, because it has the appropriate after-sales service system, maintenance will be relatively promptly. Second-hand construction machinery then perhaps go wrong at any time, even if you can get the most timely maintenance service, perhaps never as complete as the new machine used excavators, simple construction schedule Formation of 30 used excavators, and service is paid a. This is necessary to question the primary consideration when purchasing used construction machinery. About purchase of second-hand construction machinery users, the most concerned about the job is the procurement of equipment is not good value for money? South China Excavator used excavators recognition of the extent of the user is higher than the north. Used construction equipment abroad has a very complete evaluation criteria, which are mostly sold auction-based. This evaluation can be most used construction equipment users do not have. About direct users, in China has not improved the evaluation criteria used equipment when scratched used excavators, indecipherable use within one of the most simple way to evaluate the used construction machinery is particularly important. Surround excavator machine performance open discussion. Thinking of an induction motor pumps, valves, power to match a load of traffic in this part of the engine of a pump conditioning pump. Ensure that the pump of the engine's power simply absorbed into hydraulic energy; in this part of the valve of a load control valve opening, the intention in the case of pressure varies with the load to change the way the SBI rate at any time to maximize the hydraulic energy. In both periods respectively conditioning and complete the overall power to match the engine of a hydraulic system of a load. Hunan Sunward beginning of the "engine of a hydraulic system, a load of a performance system," the overall power of the current match excavator development operations. Sunward SWE85 excavators now in its sub-module test and gradually make use of the small circle of used excavator price, Kim Ho used excavators (online consultation), used excavators by Shanghai Used Construction Machinery Co., Ltd. Jin Hao. Shanghai Jin Hao Used Construction Machinery Co. (www.jinhaosh.cn) is the Shanghai Minhang District, mining machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Kim Ho used excavators in leadership with the staff warmly welcome all inquiries negotiations to create jinhao used excavators better future.
