Abstract: A freight container in the form of a tractor-trailer or intermodal container which is convertible for selectively carrying solid freight or bulk liquid freight including a housing, a plurality of collapsible tanks in the housing, liquid outlets in the tanks and conduits in communication with the liquid outlets located entirely within the housing and an opening in the housing proximate the outlets of the conduits. A liquid washing assembly is permanently mounted on the tanks both in the expanded and collapsed conditions of the tanks. Guide structure is provided in association with the frame of the collapsible tanks for guiding the frame in a perfectly vertical direction both when the tanks are being expanded and being collapsed. The upper and lower edges of the tank sides are bolted and clamped to their associated frames. Hot air ducts encircle the liquid conduits in the bases of the tanks.

Also, the bases of the tanks include pipe structure which permits the bases to be of relatively small depth.

Abstract: Improvements in a freight vehicle having a cargo space convertible from that suitable for handling piece goods to that suitable for bulk material. A conventional cargo space for piece goods has openings for filling and discharging bulk material. A double-walled inflatable bag having its bottom attached to a rigid support platform is positioned in erected condition to handle bulk material and is movable to a stored position near the roof of the cargo space to allow handling of piece goods.
