RR-Series Ultra-Precision Double-Acting High-Tonnage Hydraulic Cylinders

Precision Dual-Circuit Power for Massive Industrial Lifting and Positioning

Engineered for Absolute Control
When standard jacks reach their limit, the RR Series takes over. Designed for heavy-duty industrial applications, these Double-Acting cylinders provide hydraulic power for both extension and retraction. Unlike single-acting springs that can be slow or unreliable under load, our dual-circuit system ensures rapid, controlled retraction and the ability to apply "pulling" force, making it the ultimate tool for complex bridge engineering, shipbuilding, and structural maintenance.
