Abstract

An example wheel restraint includes a wheel chock that is manually movable between a retracted or release position clear of a wheel of a vehicle at a loading dock and an operative position to block the path of the wheel. In the release position, the chock can be manually moved freely along a track that is mounted to a driveway of the dock. When the chock is manually moved from its release position to its operative position, a locking feature automatically restricts the movement of the chock relative to the track. When the chock is manually moved back to its release position, the locking feature automatically disengages. Although the wheel chock is connected to a track, much of the force exerted by the wheel against the chock can be transmitted directly from the chock to the driveway.
