WHEEL CHOCKING DEVICE AND METHOD FOR USING THE SAME

摘要

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).
