Telescopic Hydraulic Cylinder for Tipper Truck Lifting

Telescopic Hydraulic Cylinder, also known as multi-stage Hydraulic Cylinder or combined hydraulic cylinder, is a very practical Multi Stage Hydraulic Cylinder. According to the different telescopic stages, they can be divided into 2, 3, 4 and 5 telescopic cylinders. At the same time, they can be divided into single-acting and double-acting multi-stage hydraulic cylinders according to the number of times of liquid supply to complete a working cycle.

The telescopic hydraulic cylinder is made up of two or more piston-type hydraulic cylinders, and the piston rod of the former piston cylinder is the cylinder of the latter piston cylinder. 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 point, the cylinder with the second effective area of the piston begins to extend. This extension sequence is extended from large to small, and a long working stroke can be obtained. At present, it is widely used in various machinery, such as cranes and dump trucks.
