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 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, a large second-hand digging machine trading, China's construction machinery products, annual consumption of oil is higher than the annual cost of the total output value of construction machinery. At present the United States, Japan and other market access barriers are constantly rising, the big hand digging machinery, in setting trade barriers to limit emission 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. Looking back on the development and progress excavator stage, in the next phase of market development, a large second-hand digging machine business, previously in use more single excavator, excavators now use diversity, in erecting an external device can be a great job other types of jobs. Most business development advantages excavators currently still in the current subway, underground commercial city, and even coal mine construction speed, high security requirements. In China has a great geographical location, rich resources of space is great, Anhui big hand digging machines, in the continuous reduction of resources and living space have had to prove that the country has a very large market resources waiting to be tapped. When coming into the stage in a golden period of development of the underground excavator will play a very important role. It is to make us witness the development of domestic excavator, also met a great leap forward for future development of human civilization.
