During the 11th Five-Year Plan period, China's agriculture, water conservancy, energy, transportation, information technology, construction, and environmental protection sectors experienced rapid growth. This expansion created a significant demand for mechanical equipment to support infrastructure development and industrial progress. As industries became more automated and technologically advanced, the need for high-performance and reliable hydraulic, pneumatic, and sealing components increased substantially.
According to preliminary estimates, the domestic demand for hydraulic, pneumatic, and sealing products is expected to grow from 20 billion yuan in 2005 (including approximately 900 million U.S. dollars in imports and nearly 300 million in exports) to around 35 billion yuan by 2010. Specifically, hydraulic product demand is projected to rise from over 10 billion yuan to 20 billion yuan, while pneumatic products will increase from nearly 3 billion to over 5 billion. Sealing products are expected to grow from over 3 billion to 7 billion yuan, and hydraulic products are anticipated to jump from over 1 billion to over 2 billion yuan.
Construction machinery is the largest consumer of hydraulic components, accounting for 42.3% of industry sales, with this share expected to grow in the coming years. The development of construction machinery has therefore become a critical area of focus. It is estimated that by 2010, the annual demand for hydraulic excavators will reach 60,000 to 80,000 units, bulldozers (over 120 horsepower) will reach nearly 10,000 units, loaders will be around 100,000 to 120,000 units, graders about 2,000 units, road rollers approximately 1.5 million tons, construction cranes around 20,000 units, forklifts about 80,000 units, and cement mixers nearly 10,000 units.
In addition, China currently operates around 1.4 million pieces of construction machinery, with projections indicating an increase to 2 million by 2010. It is also reported that domestic companies import approximately 150 million U.S. dollars worth of hydraulic components annually for equipment such as excavators, road machinery, and cement mixers.
In summary, the market for hydraulic systems and sealing components used in construction machinery and maintenance is poised for substantial growth, marking the beginning of a new era of opportunity and development in the industry.
