Abstract: A freight container in the form of a beam tank is disclosed which comprises two end frames (12) and a tank which spans between the end frames. The tank is encircled by strengthening rings (28). Eight saddles (14), four at each end, join the rings (28) and hence the tank to the end frames (12). The end frames comprise vertical and horizontal members (16, 18), ISO corner fittings (20), bracing members (22) and plates (24) welded into the triangular spaces bounded by the members (16, 18, 22). Each saddle (14) comprises a tubular member (32) welded at one end to the end frame. At the other end of the tubular member there is a welded-on plate (34) which closes-off the member (32). A further plate (36) of arcuate section is welded to the member (32) and is also welded to the ring (28). The plate (36) has wings which extend on each side of the member (32) and are welded to the ring (28).
