According to the China Construction Machinery Industry Association statistics analysis, China's major Chinese construction machinery equipment to maintain about 5.61 million -608 million units used excavators 400, by the end of 2013 of a hydraulic excavator market eight years market to maintain about 1,150,800 units. Largest holdings after the market provides the foundation and broad space for development, after many engineering machinery enterprises have increased investment in the market in order to obtain a new breakthrough in the industry downturn of the situation. Looking back on the development and progress excavator stage, in the next phase of market development, earlier use of more single excavator used excavators, excavators now use diversity, in erecting an external device can be a great job to 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 used excavators 607 is great, 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.
