Abstract

A rescue vehicle has a crane boom, hoist winch and rescue winch mounted on a crane turret that is rotatable about a vertical axis. A cable from the respective winches are extended along the crane boom to an associated block that is mounted near the outer end of the boom. Another block is mounted on the bumper of the vehicle to receive the cable from the rescue winch. The rescue winch is ten to twenty times more powerful than the hoist winch. During a vehicle retrieval operation the rescue winch is used to provide the horizontal pulling power while the hoist winch is used to provide the vertical pulling power. A Y-shaped stay bar is mounted on the block on the bumper and is used to support the crane boom at its outer end.
