A freight container for flowable substances comprising a fully closed vessel formed at least partly of cylindrical sheet metal, two rectangular end frames interconnected by corner fittings for lifting and stacking the freight container and saddle members connected to the vessel and respective frame members. According to preferred embodiments, the saddle members are formed of sheet sections of an arched area and planar triangular surfaces adjacent opposite lateral edges of the arched area, each of the saddle members being interposed between an adjacent corner of the end frames and the vessel. The arched area has a conical surface having an apex located near an associated corner of the end frames and an arcuate base edge curved to conform with the wall of the vessel. Each of the triangular surfaces has an axial outer edge beginning near the apex of the conical surface and extending outwardly therefrom and being connected to an adjacent one of the members of the end frames. The saddle members support the tank in a manner so as to accept loads in horizontal, vertical, axial and radial directions. |
