Abstract
Abstract A mixer truck for shipping molten metals in an elongated, substantially cylindrical vessel, which has an end portion with a plurality of annular bearing rings extending therearound, comprises a truck body with a frame plate girder which is universally mounted on the body. The frame plate girder carries two spaced sets of rollers forming a rotational cradle support for each of the ring members on the cylindrical vessel. A drive motor, carried on the universally mounted frame plate girder, is connected to drive a sprocket wheel or gear extending around the vessel between the rings.
