ABSTRACT:
The mechanical vehicle restraining device of the present invention secures a truck or other parked vehicle to a loading dock by locking onto the vehicle ICC bar thereby securing the vehicle. The device includes a base mounting plate mounted on the face of the loading dock wall and a hook positioned to move vertically within a frame guide attached to the base mounting plate. A counterbalance weight is positioned to move vertically within a second frame guide adjacent to the hook frame guide. The hook and the counterbalance weight are connected by a flexible cable. By manually depressing the hook, the hook moves down and the counterbalance weight moves up to engage a latching device. When the latching device is released, the counterbalance weight moves down thereby raising the hook until the hook engages the ICC bar.
