ABSTRACT:
A multi-condition responsive vehicle restraining apparatus includes a hook member having an edge for contacting an ICC bar on a vehicle and a tip located at one end of the edge and extending upwardly therefrom for restraining the ICC bar from passing the hook member. A beam arrangement mounts the hook member and is movable for moving the hook member on a forward stroke from an inoperative lowered toward an operative raised position and on a return stroke away from the operative raised toward the inoperative lowered position. A double-acting hydraulic cylinder is connected to the beam arrangement for actuating the same to move the hook member on its forward and return strokes. Components are provided for sensing the presence of any one of three conditions concerning the placement of the vehicle ICC bar with respect to the hook member and concurrently therewith providing an indication of which condition prevails. The conditions are that restraint of the vehicle has been either properly engaged, improperly engaged, or missed.
