Application

The Aluminum Hydraulic Cylinder Series is designed for lifting, positioning, maintenance, and load-handling applications where portability and ease of transportation are critical. Manufactured from high-strength 7075-T6 aluminum alloy, these cylinders provide the same powerful performance as conventional steel cylinders while significantly reducing overall weight.

Widely used in construction, bridge maintenance, power generation, mining, railway systems, shipbuilding, and industrial plant maintenance, the series is particularly suitable for field operations that require frequent equipment relocation. The lightweight design helps improve operator efficiency, reduce transportation effort, and simplify setup in remote or hard-to-access working environments while maintaining reliable lifting performance and durability.
