This year, the annual demand for hydraulic excavators is about 60,000 units.

In recent years, the development of industries such as agriculture, water conservancy, energy, and transportation in China has been relatively rapid. Therefore, a large amount of mechanical equipment is needed to meet the needs of its development. With the improvement of industrialization and automation, these equipments need a large number of high performance and high reliability hydraulic pneumatic and sealing elements. According to preliminary estimates, it is expected that the total domestic demand for hydraulic, hydraulic, pneumatic and sealing products will increase from 20 billion yuan in 2005 to about 35 billion yuan by 2010. Among them, hydraulic products increased from more than 10 billion yuan to 20 billion yuan, hydraulic products from more than 1 billion yuan to more than 2 billion yuan, pneumatic products from nearly 3 billion yuan to more than 5 billion yuan, and sealed products from more than 3 billion yuan Yuan increased to 7 billion yuan.

Among them, construction machinery is the largest user of hydraulic products, accounting for 42.3 of the industry's sales, and the proportion will increase in the future. It is estimated that by 2010, the annual demand for hydraulic excavators will reach 60,000 to 80,000 sets, the loaders will be about 100,000 to 120,000, the levelers will be about 2,000, the rollers will be about 15,000, and the construction cranes will be about 20,000. About 80,000 forklifts. In addition, China currently has about 1.4 million engineering machinery and is expected to reach 2 million by 2010.

Each year, hydraulic components imported from domestic companies, such as excavators, road machinery, cement mixers, etc., have reached more than US$150 million. In short, the market for hydraulic equipment and seals used in construction machinery and maintenance will face a new era of great development.
