A wheel chocking device (13) having a wheel chock (34) that can be raised from a retracted position to a raised position. In the retracted position, the wheel chock (34) is substantially flat, thereby allowing a truck (36) to be driven over the wheel chock (34). In the raised position, the wheel chock (34) can be engaged with the wheel (36) of a truck to prevent the truck from driving away from a loading dock. In one embodiment, movement of the chock (34) is provided by pneumatic cylinders (120) that drive cables (124) or chains associated with pneumatic pistons (122) positioned within the cylinders (120). As the chock (34) is moved from the distal position, the chock (34) can raise from a lowered position to an intermediate position (3). The chock (34) is then moved toward the vehicle wheel (36). Upon contact with the wheel (36), the chock (34) will raise from the intermediate position to the fully raised position. In another embodiment, the chock (136) can be inserted laterally from the side of the wheel (36).

La présente invention concerne un dispositif de calage de roue (30) possédant une cale de roue (34) qui peut passer d'une position rétractée à une position relevée. Dans la position rétractée, la cale de roue (34) est sensiblement plate permettant de ce fait à un camion (36) de se placer sur ladite cale de roue (34). Dans la position relevée, la cale de roue (34) est mise en contact avec la roue (36) d'un camion pour empêcher ledit camion de quitter un quai de chargement. Dans un mode de réalisation, le mouvement de la cale (34) est fourni par des cylindres pneumatiques (120) entraînant des câbles (124) ou des chaînes associés à des pistons pneumatiques (122) situés dans des cylindres (120). Lorsqu'on déplace la cale (34) de sa position distale, la cale (34) se relève d'une position basse à une position intermédiaire (3). On déplace alors la cale (34) vers la roue du véhicule (36). Au contact de la roue (36), la cale (34) passera de la position intermédiaire à la position entièrement relevée. Dans un autre mode de réalisation, la cale (136) peut être glissée latéralement du côté de la roue.
