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.
Claims9
A van for transporting compressible materials comprising:
- a. an enclosure having two sides, a top and a bottom and two ends, to receive the materials.
- b. a bulkhead disposed within the enclosure.
- c. pulling bars removeably positioned against the bulkhead.
- d. a cable assembly removeably attached at one end to the pulling bars, to move the bulkhead, and to a forward floating block of a pulley arrangement at the other end.
- e. a pulley arrangement in the cable assembly fixedly attached to a power winch at one end.
- f. the power winch located outside the enclosure.
- g. track members fixedly attached to the side walls of the enclosure.
- h. locking bars less than the width of the enclosure but wider than the bulkhead removeably engaged with said track members.
- i. the pulling bars being of a length substantially equal to the width of the bulkhead.
- j. the cable assembly being constructed and arranged to permit the pulling bars and bulkhead to be disposed a substantial distance outside of the enclosure and outside of the rear of the van to permit a substantial amount of the compressible materials longer than the length of the van to be initially pulled within it by the cable assembly, pulling bars and bulkhead.
