Hydraulic jacks feature a compact structure, stable pressure output, precise control, and adjustable lifting speeds. In subway tunnel construction, they enable micro-adjustment and accurate alignment of tunnel segments, ensuring extremely small assembly deviations. This significantly improves installation efficiency and safety, making hydraulic jacks ideal equipment for achieving high-precision tunnel segment assembly.

Center-hole jacks feature a hollow piston rod that allows tendons or steel bars to pass through the center. During slip-form construction of high-rise buildings, they enable accurate tensioning and releasing of steel tendons or support rods. This ensures uniform force distribution and continuous formwork lifting, significantly improving construction safety and efficiency. As such, they are indispensable equipment in slip-form engineering.

Hydraulic pancake/flat jacks feature an extra-thin, low-height design with strong lifting force. They are highly effective for bridge bearing replacement or lifting operations in confined spaces. These jacks can be easily positioned and operated within minimal clearances, ensuring safe, reliable, and efficient lifting, making them a preferred solution for tight-access lifting operations.

Hydraulic double-acting horizontal jacks provide bidirectional force for both pushing and pulling. When paired with tunnel lining trolleys, they enable smooth and rapid movement during underground construction, significantly improving operational efficiency and safety.
