ABSTRACT:
A combination portable hoist, crane, and automobile towing mechanism is adaptable into three configurations. As a portable hoist, a vertical mast and hydraulically actuatable boom are mounted on a standard support having support legs oriented in a "V", with the hoise boom positioned between the support legs. As a portable crane, the mast and boom are mounted onto a platform on a modified truck bumper in a manner to pivot 360 degrees about the axis of the vertical mast. The portable crane can therefore load and remove objects to/from the truck bed. As an automobile towing mechanism, the mast and boom are locked in position within the plane of movement of the boom normal to the vehicle rear bumper. A typical automobile bumper and axle attachment towing device is attached to the boom chain. Stabilizer bars orient the bumper and axle attachment towing device parallel to and spaced from the vehicle bumper, so that the tow vehicle may elevate one end of a towed vehicle for towing in a conventional manner.
