Abstract
An improved vehicle restraint for preventing movement of a vehicle such as a truck away from a loading dock during a loading operation. The vehicle restraint includes a guide frame mounted on the front face of a loading dock and a vehicle restraining device is movable on said guide frame from a lower storage position to an upper operative position where it engages the ICC bar on a truck. A biasing mechanism serves to bias the restraining device upwardly to the operative position while a power operated drive mechanism acts to drive the restraining means downwardly to the storage position. The restraining device includes a slide or carriage that moves on the guide frame and a hook that is pivoted to the slide. A linkage connects the frame and the hook in a manner such that the force of the biasing device will not only move the slide upwardly on the guide frame but will also pivot the hook upwardly relative to the slide.
