The development of agriculture, water conservancy, energy, transportation and other industries in China is developing rapidly. Therefore, a large number of mechanical equipment is needed to meet the needs of its development. With the increase in the level of industrialization and automation, these equipments need to support a large number of high performance and high reliability of hydraulic pneumatic and sealing components. Preliminary estimates, is expected to 2010 the total demand for hydraulic, hydraulic, pneumatic, sealing products, will be increased from 20000000000 Yuan in 2005 to about 35000000000 yuan. Among them, the hydraulic products more than 100 billion yuan by increased to 200 billion yuan, hydraulic products by more than 10 billion yuan increased to more than 20 billion yuan, pneumatic products by nearly 30 billion yuan increased to more than 50 billion yuan, sealing products from more than 30 billion yuan increased to 70 million yuan.

Which works machinery is the largest user of hydraulic products, accounting for 42.3 of the industry's sales, the future will expand the proportion of. It is expected to 2010 hydraulic excavator annual demand amounted to about 6 million to 8 million units, about 10 million to 12 million units, flat machine about 2000 units loader, roller about 1.5 million units, engineering crane about 2 million units, forklift approximately 8 million units. In addition, China now has about 1400000 construction machinery, is expected to reach 2000000 units in 2010.

In another development, the annual domestic enterprises in the production of excavators, road machinery, cement mixing truck supporting the import of hydraulic pieces, approximately $1.5 billion above. In short, for the construction machinery, maintenance of hydraulic and sealing parts of the market will face a new era of big development.
