Abstract: A sectional, free-floating floor which can slide upon rails, where such floor sections can be pulled via a cable by a motorized cable puller, such as a winch or similar manually operated pulling machine. The invention can be placed without fasteners within a loading vehicle such as a pickup truck, and any material can be loaded upon the floor sections described. The cable puller can be energized in a direction such as to pull the floor section furthest from the vehicle bed end and push each of the adjacent unattached floor sections along with it. This pulling continues and each of the floor sections are pushed, one after another, until each of the floor sections fall off of the end of the bed of a loading vehicle, dumping any material that is on each floor section off of the vehicle. The invention can also be used in military supply trucks.
