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.

Selon l'invention, un exemple de dispositif de retenue de roue comprend une cale de roue qui est manuellement mobile entre une position rétractée ou libérée, dégagée d'une roue d'un véhicule à une plateforme de chargement, et une position fonctionnelle pour bloquer le trajet des roues. Dans la position libérée, la cale peut être manuellement déplacée librement le long d'un rail qui est monté sur une voie d'accès de la plateforme. Lorsque la cale est manuellement déplacée de sa position libérée à sa position fonctionnelle, un élément de verrouillage limite automatiquement le déplacement de la cale par rapport au rail. Lorsque la cale est manuellement déplacée pour être ramenée à sa position libérée, l'élément de verrouillage se désolidarise automatiquement. Bien que la cale de roue soit reliée à un rail, la plus grande partie de la force exercée par la roue contre la came peut être transmise directement de la cale à la voie d'accès.
