Project machinery industry is machinist job one of main pillar industries, sale reached our country 2005 126.2 billion yuan, profit 45. 500 million yuan, exit is achieved collect 29. 400 million dollar, 2006 advocate business Wu income continues with of 28.36% add fast achieve give 162 billion yuan new tall, one of 4 large base that our country is manufacturing industry of international project machinery () of the United States, Japan, European Union, China. But in competition of domestic and international market, product technology level and core technology are the crucial factor that restricts competition ability to rise, with international advanced level is compared, average difference is controlled in 15 years, main show is in product utilization reliability, overall quality of life, exterior and informatization technology level. These difference are mirrorred in field of level of fundamental assembly technique centrally. Accordingly, promote development of project machinery industry, should put footing in field of level of technique of promotion foundation assembly, increase technical innovation strength, and complementary support with policy sex, the policy sex that developed in the past to lead plane product supports move to arrive on development base component. Main and crucial technology has the following 8:

1, technical name: Motivation shifts gear gear-box design makes a technology

The technology explains: Motivation shifts gear gear-box is the core part that project machine motivation delivers, although breed norms is more, its function is same, the crucial technology in designing research and development to make has general character. Homebred now motivation shifts gear advanced level compares gear-box and international, pitch of much, a confusion of voices, life weak point and leakage oily circumstance produce breakdown from time to tome. To raise level of main product technology, motivation shifts gear gear-box design production technology is waited for urgently tackle key problem rise. Motivation shifts gear gear-box design makes a technology include research and development method, electro-hydraulic control technology, craft production technology, experiment technology, material handles a technology, it is the integrated and compositive technology of a systematization. The proposal passes the development train of thought of transfer of technology and union of own innovation photograph, execute project invite public bidding to fulfil, again complementary give aid to with policy sex, execute a project to dog administrative method, make project research and development works to be carried out by the target reach the designated position.

2, technical name: Wet design of drive axle of apply the brake makes a technology

The technology explains: Wet drive axle of apply the brake is project machine product walk component, it has efficiency of maintenance-free, drive tall, life is long, the use that reduces lead plane greatly upholds charge. The material that crucial technology is designing method of software, test, axle housing at research and development is qualitative technology, as wet as the displacement that casts bevel gear of form of technology, beat attrition piece material and production technology. At present home has Inc. of willow project machine and Germany only " ZF " the joint ventures production of the company, but the price is high, downstream enterprise is accepted hard, need undertakes homebred change technical research and development.
