Single-acting piston cylinders use hydraulic pressure to either extend or retract a single piston rod from a cylinder. Generally, gravity or another external force returns the piston rod to its no-pressurized state.
Telescopic cylinders used in conventional dump trucks are oriented vertically. Therefore, the weight of the dump body and the cylinder itself may provide enough force to fully retract the cylinder.
Large quantity production.In a welded rod hydraulic cylinder, the barrel is welded directly to the end caps.
Standard Tie rod cylinder，Large quantity production.ROD:Steel, induction hardened to 45-50 Rockwell C and chrome plated 0.001″
Used where the shortest possible column length is required and a mounting plate is available.
