When a normal working stroke of a hydraulic cylinder is not feasible for the task required, telescopic Hydraulic Cylinder is employed. A telescopic hydraulic cylinder is nested in stages where the effect of the piston is expanded over multiple barrels fitted perfectly in a small main sleeve.
As most telescopic hydraulic cylinders are fitted together within a sleeve, which is almost 20% of the actual working length, they provide a better working stroke. Given its compact size, a telescopic hydraulic cylinder is used when a conventional single-rod hydraulic cylinder is not feasible.
A telescopic hydraulic cylinder works on a similar principle to Single acting Telescopic Hydraulic Cylinder and Double Acting Telescopic Hydraulic Cylinder. The main difference between the two types is that in telescopic cylinders the piston or barrel is nested in a compact housing along with other tubes which extend together with the extension of the piston or the main barrel.
