Abstract
Vehicle restraints for use at loading docks are described herein. In some embodiments, a vehicle restraint includes a vertically-moving carriage that is operably coupled to a guide track by means of one or more sliding members instead of, or in conjunction with, rollers. The sliding members can have relatively large contact surfaces configured to react the majority of vehicle pull loads applied to the vehicle restraint in use. Because of the relatively large contact surfaces, the pull loads are spread out over a relatively large area of the guide track, thereby reducing the likelihood for the loads to deform or otherwise damage the guide track.
