Along with the importance of environmental protection as well as for oil and other fossil fuel prices soaring, energy saving products of construction machinery engineering machinery enterprises have become a new weapon for the market. Qi Jun believes that second-hand excavator market analysis, take the road of energy saving is also a great way to break the Chinese Enterprises of Foreign Trade Barriers. By the end of 2011, China's annual consumption of oil engineering machinery products cost higher than the annual output value of construction machinery. At present the United States, Japan and other market access barriers are constantly rising, trade barriers settings, limit emissions standards bear the brunt. But Qi Junqiang tone, as energy saving construction machinery industry is difficult, more subject to technical bottlenecks, fuel quality, user habits and other issues, so the research and development efforts to improve the applicability of compatibility must be accompanied by the EFI Intelligent of the advantages of a more effective dissemination of professor to end customers. As mechatronics technology widely used in construction machinery, intelligence has become a trend of construction machinery. Host manufacturers to highlight their own EFI technology, second-hand excavator market place, but also attaches great importance to information technology research excavator, fault recording and diagnostic systems. Made more prominent in this regard, such as Doosan, took TMS remote fault diagnosis and analysis system provides fault interpretation and multi-mode solutions, through remote fault diagnosis system, real-time monitoring of the status of the machine, and timely contact with the owner or operator, maintenance or troubleshooting, and its after-sale technical staff also has a hand-held terminal, after the handheld terminal is coupled with the machine's control system, used wheeled excavator market, download all failure data, used excavators market in Changsha, offline analysis, to understand the whole state, providing sound advice and solutions.
