Taizhong Group Yuci Hydraulic Industrial Co., Ltd. is a wholly-owned subsidiary of Taiyuan Heavy Machinery Group Co., Ltd. and serves as an influential base for the independent R&D and manufacturing of high-end hydraulic products. The company originated as Yuci Hydraulic Parts Factory, 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 nationally recognized "High-Tech Enterprise." The company has a national enterprise technology center and a postdoctoral research station, ranking among the top in the industry in high-end hydraulic product design and electromechanical-hydraulic integrated control. The company has participated in formulating 29 national and industry product standards and obtained 162 invention and utility patents. The company owns internationally sourced, industry-unique casting, machining, and heat treatment production lines, specialized equipment, inspection, and testing devices, introduces global process technologies, and is a reliable guarantee for the R&D and manufacturing of high-end hydraulic products.

The company headquarters is located in Yuci Industrial Park, Shanxi Province's Transformation and Comprehensive Reform Demonstration Zone, and has four branch companies: casting (heat treatment), hydraulic pumps, hydraulic valves, and hydraulic systems. It has established integrated R&D and manufacturing subsidiaries in Changzhi, Jinan, and Shanghai. Its annual production capacity reaches 3 million hydraulic components, 40,000 sets of hydraulic systems, and 35,000 tons of various castings. Its products include high-pressure piston pumps, vane pumps, gear pumps, hydraulic valves, hydraulic motors, cylinders, integrated hydraulic systems, and various castings, widely used in construction machinery, Agricultural machinery, transportation (locomotives, rail transit, ships), petroleum machinery, metallurgy and steel, coal mining, marine engineering, aerospace, water conservancy and electric power, machine tool industry, chemical equipment, and other fields. The company has supplied products for key national projects such as the Three Gorges Project, South-to-North Water Diversion, slab continuous casting and rolling production, and the localization of wide-plate hot rolling production lines.　

The company continues to strengthen its innovation-driven approach, with products and technologies steadily expanding into high-end manufacturing fields. Substantial breakthroughs have been made in the localization of high-end high-pressure plunger pumps; High-pressure valve and multi-way valve products have overcome operational reliability and sealing technical challenges under high pressure, high temperature, and high frequency environments, meeting the high-end main machine requirements of mobile machinery; Continuous innovation and development of electromechanical-hydraulic integrated hydraulic system technology, undertaking hydraulic system projects for hoists and ship lifts in all key national water conservancy and hydropower projects, including the Three Gorges Project; It overcame challenges in the main hammer cylinder and hydraulic control technology and processes, successfully supporting the first fully hydraulic offshore pile driving hammer developed by Taizhong, filling a gap in hydraulic control technology for pile hammers.

The company has established a nationwide marketing and service network, wholeheartedly providing customers with perfect service. Actively implementing an internationalization strategy, it has strategic partners and service organizations in Europe, the Americas, Asia, Africa, and other regions.

The company is committed to revitalizing China's hydraulic industry, vigorously promoting independent innovation, and supporting the development of high-end equipment manufacturing.
