Abstract
A lift mechanism for mounting on the back of a motor vehicle having a trailer hitch. It includes a rearwardly extending tube mounted on the trailer hitch. A main hoist column is upstanding on the rearwardly extending tube. The main hoist column has an upper end which is attached to the back of the motor by a connection which allows both pivotal and back and forth movement of the upper end. First and second platforms are mounted by sleeves to move up and down on the main hoist column with the sleeves guided by rollers. Each platform can be swung between a horizontal position and a vertical position. An electric motor driven drum is provided for each platform with a cable wound around each drum having an end connected to its respective platform. A removable extension attaches to the rearwardly extending tube to provide a lower extension for the main hoist column.
