Abstract
Abstract A rolling loader designed particularly to be mounted on the rear bumper of a pickup truck for facilitating the loading of heavy objects onto and off of the bed of the truck. The loader includes a heavy, steel pipe having a pair of ball bearing assemblies fitted within each end thereof. A pair of L-shaped brackets have their horizontal plates fastened to the top surface of the bumper. A solid shaft is secured to the vertical plate of each bracket and extends through a central aperture formed in each ball bearing assembly so as to define a horizontal axis for the tube. The brackets are mounted to the bumper so that the rear most and top most portions of the tube extend respectively beyond the rear edge of the bumper and the level of the bed of the truck.
