Our Company

The predecessor of the our company is YUCI hydraulic parts factory, founded in 1964, is known as the cradle of China's hydraulic industry.Is China's largest and competitive high-end hydraulic products independent research and development, manufacturing base.

The company integrates research, development and manufacturing of high-end hydraulic products, and is a "high-tech enterprise" recognized by the state. The company has a national enterprise technology center and a post-doctoral research station and maintain its leading position in designing of high-end hydraulic product and controlling of mechanic-electric-hydraulic integration and other fields. The company participated in formulating 21 national and industrial product standards, and obtained 24 invention and practical patents, and won 66 technology progress awards and outstanding new product awards. The company has advanced casting, machining, heat treatment production lines, special equipment and inspection, test equipment, introduce advanced processing technology as a reliable guarantee of high-end hydraulic products.

The company consists of four branches: Hydraulic Pump Branch, Hydraulic Valve Branch, Hydraulic System Branch and Casting Branch, there are three subsidiaries of R&D and manufacturing in Changzhi, Jinan and Shanghai. They produces 3 million units of hydraulic components, 40 thousand sets of hydraulic system equipment, 35 thousand tons of hydraulic castings annually, including high-pressure piston pump, vane pump,gear pump, hydraulic valve, motor, hydraulic cylinder, hydraulic system and castings. They mainly used in engineering machinery, agricultural machinery, transportation (locomotives, rail transit, ships), petroleum machinery, metallurgical steel, coal mines, marine engineering, aerospace, water conservancy and power, machine tool industry, chemical equipment and other fields. The company has provided products for national key projects such as the Three Gorges Project, the South-to-North Water Transfer Project, the localization of metallurgical slab continuous casting and rolling production line and so on. 

The company continues to strengthen innovation drive, products and technology continue to expand to high-end manufacturing. Substantial breakthroughs were made in the localization of high-end high-pressure plunger pumps; High-pressure valve and multi-way valve break through the difficult problems of operation reliability and sealing technology under high pressure, high temperature and high frequency and reach the leading level in China. The technology of hydraulic-electro-mechanical occupies a leading position in China and undertakes the hydraulic system project of hoist and ship lift of all national key water conservancy and hydro-power projects, including the three gorges project; It has overcome the difficulties in the main hammer oil cylinder and hydraulic control technology and technology, and successfully matched the first set of hydraulic Marine pile hammer which is TZ researched and developed, and filled the blank in the field of hydraulic control technology of pile hammer.

The company has established a complete quality management system, with the certification of informatization and industrialization "two-oriented integrated management system", and comprehensively implemented refined management to constantly improve product quality and economic benefits.

The company has established a nationwide marketing and service network, dedicated to providing customers with perfect services. We have actively promoted the internationalization strategy and established strategic partners and service agencies in Europe, the Americas, Asia and Africa.

The company upholds the core values of "integrity, innovation, leanness, excellence" and takes the revitalization of China's hydraulic industry as its responsibility to vigorously promote independent innovation and help the development of high-end equipment manufacturing industry.
