ABSTRACT:
A cargo flow control system for bulk cargo containers. The system uses an inflatable bag positioned between the floor of the container and the cargo. When the bag is inflated, it slopes downward from the front of the container to the discharge door at the rear of the container. When the slope is greater than the angle at which the bulk cargo naturally flows, the container can be unloaded without using other unloading techniques such as tilting the container. The system can be used with or without a liner. When used with a liner, it can be manufactured as an integral part of the liner, or as a separate unit.
