Abstract

A chocking system for securing a vehicle to a deck which has a track extending therealong includes a pair of frames mounted on said track for movement along the track and hingedly mounted for swinging movement toward and away from the deck. A wedge is mounted on each of the frames and can be moved toward and away from the track. An L-shaped arm is pivotally mounted at one end on each of said wedges and has a shoe at its other end which can extend over and contact the peripheral surface of a vehicle wheel. The arms are adapted to overlap along their elbows and have means for releasably securing them together with the shoes being over the vehicle wheel. The frames can be lifted away from the deck to provide a clear deck for movement of the vehicles along the deck. With the vehicle in position on the deck, the frames are movable back onto the deck with a wedge being positioned at each side of the vehicle wheel to prevent movement of the vehicle along the deck. The arms are then pivoted to place the shoes over the wheel to lock the wheel against the deck.
