Small excavators popularity in the domestic market from the beginning of 2010, a large number of domestic customers in the purchase of further machinery mini excavators have an economic boom in the country, the construction of a continuous phase, the construction machinery market is picking up steam, used a large excavator market, small excavators in the market can be very profitable very fast like ordinary customers receive and the construction of the market in the domestic construction machinery manufacturers are also in addition to Yuchai excavators in the early 1990s, exports to Europe outside mini excavator, Almost no Chinese manufacturers of export of small excavators successful history. The current trend is changing this situation, in the so-called marketing sales unexpectedly when small and medium excavators, and what is gradually increased, the Shanghai second-hand large digging machine, which takes small excavators sales in 2012 when to be treated as a top priority. Along with the importance of environmental protection as well as for oil and other fossil fuel prices soaring, Zhengzhou used large digging machines, construction machinery and energy saving products has become the construction machinery enterprises to compete for new market weapon. Qi Jun think, 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. Komatsu large digging machines, Jin Hao used excavators, Zhengzhou big digging machine used 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.
