Taizhong Group Yuci Hydraulic Industry Co., Ltd. is a wholly-owned subsidiary of Taiyuan Heavy Machinery Group Co., Ltd. It is an influential independent research and manufacturing base for high-end hydraulic products. The company, formerly known as Yuci Hydraulic Parts Factory, was founded in 1964 and is known as the "cradle" of China's hydraulic industry.

The company integrates the research and manufacturing of high-end hydraulic products and is recognized as a "high-tech enterprise" by the state. The company has a national enterprise technology center and a postdoctoral research workstation, ranking among the top in the industry in high-end hydraulic product design, electromechanical hydraulic integration control and other technical fields. The company has participated in the formulation of 29 national and industry product standards, and has obtained 162 invention and utility patents. The company has internationally sourced and industry-specific casting, machining, heat treatment production lines, specialized equipment, inspection and testing devices, and introduces global process technology, which is a reliable guarantee for the research and manufacturing of high-end hydraulic products.

The company is headquartered in Yuci Industrial Park, a demonstration zone for comprehensive transformation and reform in Shanxi Province. It has four subsidiaries including casting (heat treatment), hydraulic pumps, hydraulic valves, and hydraulic systems. It also has research and development and manufacturing integrated subsidiaries in Changzhi, Jinan, and Shanghai. The annual production capacity reaches 3 million hydraulic components, 40000 sets of hydraulic systems, and 35000 tons of various castings. The products include high-pressure plunger pumps, vane pumps, gear pumps, hydraulic valves, hydraulic motors, oil cylinders, integrated hydraulic systems, and various castings, which are widely used in engineering machinery, agricultural machinery, transportation (locomotives, rail transit, ships), petroleum machinery, metallurgy and 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, South to North Water Diversion, slab continuous casting and rolling, and wide plate hot rolling production line localization.

The company continues to strengthen its innovation driven approach, expanding its products and technologies into the high-end manufacturing field. Significant breakthroughs have been made in the localization of high-end high-pressure plunger pumps; High pressure valves and multi way valve products have broken through the reliability and sealing technology problems in high-pressure, high-temperature, high-frequency and other environments, meeting the high-end host requirements of mobile machinery; The technology of electromechanical hydraulic integrated hydraulic system continues to innovate and develop, and has undertaken hydraulic system projects for all national key water conservancy and hydropower projects, including the Three Gorges Project, such as the hoist and ship lift hydraulic systems; We have overcome the technical and process difficulties of the main hammer body oil cylinder and hydraulic control, and successfully developed the first set of fully hydraulic offshore pile driving hammers in China, filling the gap in the field of hydraulic control technology for pile driving hammers.

The company has established a nationwide marketing and service network, dedicated to providing customers with perfect services. Actively promoting internationalization strategy, with strategic partners and service institutions established in Europe, America, Asia, Africa and other regions.

The company takes revitalizing China's hydraulic industry as its responsibility, vigorously promotes independent innovation, and assists the development of high-end equipment manufacturing industry.
