Long Stroke Crane Hydraulic Cylinder Piston Double Acting Telescopic

Double Acting Telescopic Long Stroke Crane Piston Type Hydraulic Cylinder 

      Piston hydraulic cylinder can be divided into single-rod and double-rod two structures, the fixed way by the cylinder fixed and fixed piston rod two, according to the role of hydraulic pressure has a single role and double-acting. In a single role in the hydraulic cylinder, the pressure oil is only provided in a cavity of the hydraulic cylinder, which realizes unidirectional movement of the cylinder by hydraulic pressure and external force (such as spring force, self-weight or external load) in the opposite direction; and the double-acting hydraulic cylinder piston movement in both directions alternately into the two chambers through the oil, the role of hydraulic pressure to complete, it is only one side of the piston with a piston rod, so the effective area of ​​the two chambers are different. In the oil the same amount, the different chamber into the oil, the piston speed of movement is different; in the same load force to be overcome, the different chamber into the oil, the required oil pressure is different, or set in the system pressure, sanitation Garbage truck hydraulic cylinder movement in both directions can overcome the load force is different.
