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.
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.
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.
