Abstract
A standard trailer van is disclosed which is adapted to load compressible materials in sequential steps resulting in a compressed product which allows larger quantities of the compressible product to be loaded than heretofore known. The adapted van includes a power winch and pulley arrangement located beneath the trailer van and a cable assembly which is a part of and controlled by the pulley arrangement. The cable assembly is connected to a moveable bulkhead which is used to force the compressible materials into a compressed state when activated by the power winch.
