About telescopic cylinders
Function and stroke of telescopic cylinders
A telescopic cylinder is a special type of hydraulic cylinder consisting of multiple segments. This design allows the cylinder to be collapsed telescopically and extended in stages. This enables telescopic cylinders to have a significantly longer stroke than their retracted state. Because the segments, also called stages, are nested within each other, the effective area increases with each stage. As a result, the largest stage extends first, delivering the greatest force, followed by the next smaller stage. With multi-stage telescopic cylinders, it’s important to note that at a constant flow rate, each smaller stage extends faster but delivers less force.
Applications of telescopic cylinders
Telescopic cylinders are used in various fields.
Conveyor systems: They are frequently used in conveyor systems, where they serve to lift and lower materials.
Supports: Telescopic cylinders allow for flexible adjustment to different heights.
Lifting systems: Because these cylinders are able to achieve large strokes in a relatively small installation space.
Sampling systems: Telescopic cylinders are also used in sampling systems to precisely extract samples from different heights or depths.

Protection, maintenance and sealing of telescopic cylinders
Protect your telescopic cylinder
When installing and operating your telescopic cylinder, ensure that the cylinder does not act as a mechanical stop and is installed without tension. Regular cleaning and maintenance of the seals is necessary to prevent premature wear.
