Hengli has been deeply involved in the shield tunneling equipment industry for more than ten years and can produce a complete set of shield machine hydraulic systems.Hengli also successfully provided a complete set of shield machine hydraulic systems to many domestic shield machine manufacturers.To reach a long-term strategic cooperation with a well-known domestic machinery manufacturing company, 70% of the shield machine hydraulic system is provided by Hengli. Among them, core components such as pumps and valves are independently developed by Hengli. Each component has superior performance and fully meets the needs of complex working conditions such as high frequency, high load, vibration, and pollution during underground construction. This has also realized the localization of the core hydraulic components of the shield machine's hydraulic system.
