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

The company integrates the research and development and manufacturing of high-end hydraulic products, and is a nationally recognized "high-tech enterprise". The company has a national enterprise technology center and a postdoctoral research workstation, which ranks among the best in the industry in technical fields such as high-end hydraulic product design and electromechanical and hydraulic integrated control. The company has participated in the formulation of more than 20 national and industry product standards, won 24 invention and practical patents, and won 66 national, provincial and ministerial technical progress awards and outstanding new product awards. The company has internationally purchased and industry-specific casting, mechanical processing, heat treatment production lines and special equipment, inspection and testing equipment, and introduces global process technology, which is the guarantee for the research and development and manufacturing of high-end hydraulic products.

The company is headquartered in Yuci Industrial Park, Shanxi Province Transformation and Comprehensive Reform Demonstration Zone, with four branches: casting (heat treatment), hydraulic pump, hydraulic valve, and hydraulic system. It has R&D and manufacturing integrated subsidiaries, Changzhi, Jinan and Shanghai. The annual production capacity reaches 3 million hydraulic components, 40,000 sets of hydraulic systems, and 35,000 tons of castings of various types. The products include high-pressure plunger pumps, vane pumps, gear pumps, hydraulic valves, hydraulic motors, oil cylinders, integrated hydraulic systems and various types Castings and other products are widely used in engineering machinery, agricultural machinery, transportation (locomotives, rail transit, ships), petroleum machinery, metallurgy and steel, coal mining, marine engineering, aerospace, water conservancy and electricity, machine tool industry, chemical equipment and other fields. The company has provided products for projects such as the Three Gorges Project, South-to-North Water Diversion, Slab Continuous Casting and Rolling and the Domestic Production Line of Wide Plate Hot Rolling.

The company continues to strengthen innovation-driven development, and its products and technologies continue to expand into the field of high-end manufacturing. The domestic production of high-end high-pressure plunger pumps has made substantial breakthroughs; high-pressure valves and multi-channel valve products have broken through the problems of operation reliability and sealing technology in high-pressure, high temperature, high frequency and other environments, and met the needs of high-end hosts of mobile machinery; electromechanical and hydraulics Integrated hydraulic system technology continues to innovate and develop, and undertakes the hydraulic system projects of all national water conservancy and hydropower projects, including the Three Gorges Project; overcomes the difficulties of main hammer cylinder and hydraulic control technology and process, and successfully matches it. The first full hydraulic offshore pile driving hammer developed in China by Taihong.

The company has a complete quality management system, has the "integration management system for industrialization and industrialization" certification, promotes refined management, and continuously improves product quality and economic benefits.

The company has built a nationwide marketing and service network and dedicated to providing services to customers. Actively implement internationalization strategy and set up strategic partners and service agencies in Europe, America, Asia, Africa and other regions.

The company takes it as its mission to revitalize China's hydraulic industry, vigorously promote independent innovation, and help the development of high-end equipment manufacturing industry.
