ABSTRACT:
A cam action twist lock container support assembly is provided to support freight containers upon a standard flatbed truck trailer. The support includes a cam activated twist lock assembly, which lowers the base of a locking cone of the support assembly continuously down until the locking cone has rotated 90 degrees into a locking position within each of the container supports of the freight container. A corresponding cam surface for a rotating handle, which transmits a mechanical power to the rotating locking cone, thereby ensures the locking cone within the corresponding container support. For easy carrying, the cam activated twist lock assembly may be attached to hinged, fold away support portions which rotate downward towards a standard trailer side rail to a rest position, such that the cam action twist lock assembly rotates away from a vertical position of use and stores within the outer dimensional limits of the trailer.
