ABSTRACT:
A stable lift apparatus for a pickup truck includes a base which is supported on the sidewalls of the cargo compartment. Each of a pair of scissor assemblies has two lifting arms having the front ends pivotably attached to one of the base and a raisable platform. 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. Prior to setting the stabilizer, its length is greater than the distance to the ground. Movement of the truck a short distance sets the stabilizer in a stabilizing mode.
