Single acting telescopic cylinders
Single-acting telescopic cylinders are constructed of an outer cylinder with an added number of steps. In this way we achieve a short build-in, but a long stroke. Single-acting telescopic cylinders generate a thrust of hydraulic power. For the cylinder to return to its original position, a force in the opposite direction is needed. This opposing force is usually generated by the load that the cylinder lifts.
Single-acting telescopic cylinders are equipped with a single oil connection.
