Abstract
Abstract The invention is a vehicle mounted loading hoist for use with a vehicle having a pair of spaced parallel rails positioned on a load carrying bed. A carriage is positioned for movement along the rails and a hoist is mounted on the carriage. The carriage includes a pair of axles mounting wheels which ride on the rails. A motor is positioned at one side of the carriage and drive chains on that side of the carriage are connected from the motor to the axles to selectively drive the loading hoist along the rails. An outrigger assembly is provided on the carriage. The outrigger assembly includes a mechanism for adjusting the positions of a pair of outrigger legs both horizontally and vertically. The outrigger legs may also be moved between storage and operative positions.
