Telescopic hydraulic cylinder introduction
The telescopic hydraulic cylinder has two or more stages of pistons. The order of the pistons in the telescopic hydraulic cylinders is extended from large to small, and the order of empty loading retraction is generally from small to large. The telescopic cylinder can achieve a long stroke, while the retraction length is shorter and the structure is more compact. Such hydraulic cylinders are commonly used in construction machinery and agricultural machinery. There are multiple pistons that move once, and each of the pistons changes its output speed and output force as they move.
