Convertible trailer system for hauling general cargo or liquid in bulk

Abstract

A freight vehicle has a cargo space that is convertible for handling piece goods and is also suitable for hauling liquid bulk material. A conventional cargo space is equipped with a drop-down frame and flexible liquid enclosure that is stowed in the ceiling of the trailer while hauling a full load of palletized or piece goods materials that can be lowered to the floor for transporting liquid bulk loads. Generally, the long tubular (round and or oval in shape from an end view) can be fitted with a polyethylene film disposable liner. The disposable poly liner will ensure the liquid freight is free from contamination. This concept not only eliminates the need for a liquid tanker to be washed out between each load but also allows for the hauling of piece goods freight when the frame system is raised back to the ceiling.
