  • Patent number: 5297653
    Abstract: A stable lift apparatus for a pickup truck includes a base which is supported on the sidewalls of the cargo compartment.

A pair of hydraulic cylinders moves a central pivot shaft upward to raise the platform. A portable stabilizer has a ground engaging foot adjustable in distance from the stabilizer's pivotable attachment to the lift apparatus or pickup truck.
