A heavy duty vehicle recovery system employs a crane/tow boom assembly which is pivotally mounted to an upright assembly and is transformable between various positions. Two variably positionable booms with slidable extensions are provided. The crane/tow boom assembly extends rearwardly from the lower portion of the upright assembly. When the upright assembly is in an upright position, the boom assembly is upwardly pivotal from the upright assembly. When the upright assembly is in a reclined position, the crane/tow boom assembly is pivotally transformable to a transport position generally parallel to the upright assembly. The crane booms may be independently positioned at different elevational angles and different extensions. |
