The telescopic hydraulic cylinder uses a piston (or plunger) combination of several nested barrels in different diameters. The telescopic cylinder we designed has rational structure, reliable and stable performance. It also easy to assemble, detach and repair this product. Our telescopic hydraulic cylinder is mainly used for cases in which the stroke is long, while the mounting distance or total length is short (the stroke could be longer than the mounting distance or total length). The overall stroke length is the total of strokes of different barrels. Each stage could be single action type or double action type according to your applications.
This telescoping cylinder is widely used for the telescopic boom in the crane, and some parts like dumping device in the automobile, trailer, street washer.
