Claim:
A wheel restraint system for engaging a wheel of a vehicle at a loading dock that includes a doorway, wherein the vehicle traverses an approach path as the vehicle moves toward the loading dock, the wheel restraint system comprising: a chock anchor mountable to the loading dock adjacent the approach path of the loading dock; an elongate beam mountable at the loading dock adjacent an upper edge of the doorway in a generally horizontal orientation relative to the chock anchor and positionable at a location outside the approach path, the beam being substantially parallel to and extending over at least a portion of the chock anchor; and a wheel chock coupled for horizontal movement relative to the beam and the chock anchor along the portion of the chock anchor, the wheel chock retractably coupled to the elongate beam between a blocking position and a raised position such that in the blocking position the wheel chock is inside the approach path adjacent the wheel and engages the chock anchor to impede movement of the vehicle away from the loading dock, and in the raised position the wheel chock is spaced away from the chock anchor, is spaced apart from the wheel, and is outside the approach path to allow movement of the vehicle away from the loading dock.
