Abstract
A vehicle for conveying racks of goods includes a drop frame trailer having an interior with a rear floor and a front floor, the rear floor being lower than the front floor. An anti-friction device (an array of rollers mounted to the front floor) slopes upwardly to the trailer front. A stop on the front floor is resiliently movable from a first position to a second position, the first position extending vertically above tops of the rollers, and the second position being lower than the first position. A forklift can position a rack of goods on the anti-friction device on the front floor, with the rack depressing the stop from the first position to the second position as the rack is positioned until an opening in the rack is positioned above the stop. The stop can counter a gravitational force which would cause rack movement down the anti-friction device.
