Crane Telescopic Hydraulic Cylinder

Crane telescopic hydraulic cylinder is a device that uses a hydraulic system to achieve telescopic function, and is mainly used for crane boom telescopic. It consists of an outer cylinder, an inner cylinder, a piston, a seal, a tie rod, and a hydraulic oil pipeline. The pressure of the hydraulic oil drives the piston to move, thereby driving the inner cylinder and the tie rod to telescope, realizing the telescopic function of the crane arm.
