The Hendrickson Dock Lock Actuator operates the dock-lock mechanism used in Hendrickson trailer suspension systems. This compact sleeve-type air spring extends to 10.5 inches and compresses to 4.0 inches, providing the travel required to engage and release the dock-lock assembly during loading operations. A 2.65-inch-wide top plate and piston provide secure mounting while allowing the actuator to fit within confined suspension spaces. Reinforced rubber construction withstands repeated cycling and harsh operating environments common in trailer docking applications. By controlling dock-lock engagement, the Hendrickson S-SR1VA103 actuator helps stabilize trailers at the loading dock and limits suspension drop when system air pressure decreases.
