ABSTRACT:
Bulk containers of unitary construction and bulk containers formed of separate parts that interfit with one another to form a unitary structure and an apparatus that lifts the containers from a first support surface and suspends them in queued relation to one another above a second support surface. The first support surface may be a loading dock and the second support surface may be the bed of a truck. A plurality of rearwardly extending hook members are positioned on opposite sides of the truck bed at the rearward end of the truck. The hook members rotate in a vertical plane, and lift the container members, one at a time, from the first support surface by engaging outer roller members that extend laterally from opposite sides of each container. The hook members deliver the containers to horizontally disposed chain members that extend the length of the truck bed on both sides of the truck. The track members are rotatably mounted and carry the suspended containers, by engaging plural inner roller members disposed on opposite sides of the containers, toward the front of the truck bed so that the entire truck bed may be filled with the bulk containers.
