Abstract

An example wheel restraint includes a track to be positioned adjacent a vehicle approach path of a loading dock. A shuttle is pivotally coupled to the track via a track follower and pivots between a home position and a deployed position about a shuttle axis substantially parallel to and offset relative to a longitudinal axis of the track. A barrier is pivotally coupled to the shuttle and pivots between a non-blocking position and a blocking position about a pivot axis substantially parallel to and spaced apart from the longitudinal axis of the track such that the shuttle rotates in a first direction about the shuttle axis when the shuttle moves from the home position to the deployed position and bather rotates in a second direction about the pivot axis when the barrier moves from the non-blocking position to the blocking position, where the first direction being different than the second direction.
