The history of hydraulic industry development
China’s hydraulic industry started late with a weak foundation. Before the founding of the People’s Republic of China, there was virtually no hydraulic industry in the country, with only minimal use of hydraulic components in fields like press machines and machine tools. After the establishment of the nation, China’s hydraulic sector went through three developmental phases: the foundational entrepreneurship stage, the growth expansion stage, and the rapid development stage. Through years of dedicated efforts, the overall technical capabilities of China’s hydraulic industry have been significantly enhanced.
Foundation and start-up phase
During the foundational and entrepreneurial phase (year 1952-1962), China’s hydraulic industry emerged from scratch by learning Soviet technologies. Initially replicating Soviet-developed hydraulic tooling for lathe applications, Chinese manufacturers gradually established specialized production facilities in the early 1960s to independently manufacture hydraulic components through reverse engineering of existing Soviet designs.
Development and growth stageDuring the development and growth phase (1962-1978), China introduced complete sets of hydraulic technologies and equipment from Japan, gradually combining imported technologies with domestic designs. The number of hydraulic enterprises steadily increased during this period. Throughout this stage, small and medium-sized specialized hydraulic companies emerged across the country, while the application scope of hydraulic components expanded further, progressively covering fields such as machine tools.
Rapid development stageDuring its rapid development phase (since 1978), China actively introduced advanced foreign hydraulic manufacturing technologies to gradually close the gap with global industry standards. The country has established large-scale specialized hydraulic enterprises that have successfully adapted, absorbed, and localized these technologies. Today, China’s hydraulic industry boasts a professional production system with comprehensive product categories, and its applications now span across various sectors including construction machinery, mining equipment, agricultural machinery, sanitation systems, and port operations.
