ABSTRACT:
A lifting device for use on pickup trucks and the like for loading and unloading objects carried on a load support to and from the truck bed. The lifting device includes a pair of laterally spaced booms having lower ends pivotally supported on a frame. Elongated lifting arms are pivotally attached to the other ends of the booms and are, in turn, pivotally attached to the load platform. Abutment means are provided for engaging the elongated lifting arms as the booms are rotated over the bed of the truck for shortening the radius of the arcuate path of travel of the load support as the load is loaded into the truck bed.
