Telescopic Cylinders
Multi-stage hydraulic cylinders providing long stroke capability within a compact retracted length—ideal for dump trucks, trailers, and tipping systems where full stroke in limited space is essential.
Long Stroke, Compact Design
Telescopic hydraulic cylinders provide long stroke capability within a compact retracted length. They extend in multiple stages using nested tubes and hydraulic pressure, delivering smooth, high-force motion for lifting and dumping applications. Available in single- or double-acting types, they are ideal for mobile and tipping systems where full stroke in limited space is essential.
How They Work
Sequential Extension
Multiple stages extend sequentially under hydraulic pressure, each stage sliding from within the next.
Single/Double Acting
In single-acting versions, gravity or load weight retracts the stages; double-acting types use pressure in both directions.
Internal Sealing
Internal seals and bearings guide and seal between stages.
Sequential Flow
Porting is designed to control oil flow to each stage in sequence.
End-of-Stroke Cushioning
Optional cushions slow end-of-stroke impact.
When to Use
Ideal applications for telescopic cylinders
Applications requiring long extension with limited retracted length
Dump trucks, trailers, and tippers
Material handling or lifting systems where compact retraction is key
Mobile and industrial equipment needing large motion from a small space envelope
Lifting, tilting, or raising systems with heavy loads
