ABSTRACT:
A telescopic hydraulic cylinder comprises a hollow base member arranged to be supported pivotally on a mount, as by trunnions, the base member including a removable end closure at its rearward end. The interior surface of the base member incorporates a set of machined grooves which removably mount a set of rings that act as a stop, a fluid seal, a bearing and a wiper for the largest of a plurality of telescoping cylinder stages each incorporating a similar set of internal machined grooves and rings which cooperate with the adjacent smaller stage. The smallest stage receives a piston closed at its forward end which mounts a connector for attachment to a load to be moved. An internal groove on the rearward end of each cylinder stage removably mounts a lifting ring and an external groove on the rearward end of each cylinder stage and piston removably mounts a guide bearing ring for cooperation at its forward end with the stop ring of the adjacent larger cylinder stage and at its rearward end with the lifting ring of the adjacent larger cylinder stage.
