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