Abstract
Abstract A convertible transporting device in which a flexible fluid containing bag is supported in an open top container. The flexible bag fills the container when full of fluid and lies in the bottom of the container when empty. A support platform forms a movable top wall in the container supported by the bag. The platform moves downwardly in the container as the bag empties and with the bag completely empty forms a floor in the bottom portion of the container overlying the bag. With the bag empty and the platform in its lowermost position, dry freight can be stacked on the platform within the container to provide a pay load on the reverse trip.
