Product Introduction
Telescoping hydraulic cylinders are composed of a number of cylinders stacked on top of each other. Where the cylinder barrel also acts as a piston rod. Where the cylinder installation length is less than the required stroke. Most telescopic hydraulic cylinders are single acting hydraulic cylinder, but there are also double acting telescopic cylinders available.
When the pressure oil enters from the rodless cavity, the cylinder with the largest effective area of the piston begins to extend, and when it reaches the end, the cylinder with the second effective area of the piston begins to extend. The sequence of the telescopic hydraulic extension is from large to small, and a long working stroke can be obtained. The smaller the effective area of the extension cylinder, the faster the extension speed.
