Abstract: A baffle or dividing wall 13, 14 disposed in a tank is connected to the inner wall of the tank jacket 10 via a ring 15, 21 of triangular profile. The outer diameter of the intermediate wall is significantly smaller than the inner diameter of the tank so that the wall may be readily inserted into the tank. One leg 16 of the proHie ring 15 forms an extension of the curvature of the intermediate wall 13, whereas the other leg 17 closes the gusset-type region between the convex side of the intermediate wall 13 and the tank jacket 10.

Abstract: For protecting tank armatures 22 against mechanical and chemical influences from the environment, an armature box 25 is provided which is screwed to the container frame 13, 17 and sealed with respect to the tank jacket 10 by means of a permanent-elastic sealing material. The armature box 25 is inserted only after the tank armatures 22 have been mounted and thus does not impede their installation. On account of its rigid connection with the container frame 13, 17, the armature box 25 has a high stiffness.

Abstract: In a heated transport tank, the lower zone of the tank jacket 10 is surrounded by an outer shell 15 spaced from the jacket by socket-type projections 16 integrally formed in the shell 15. The outer shell 15, which forms a vapour flow chamber 20, extends throughout the axial length of the tank. At an intermediate location, where the tank is supported by a transverse bar 11 of a base structure via a transverse saddle 25, the socket-type projections 16 are reinforced by spacers inserted between the tank jacket 10 and the shell 15, each spacer being formed as a stack of comparatively thin annular discs. The individual discs are capable of conforming themselves to the local curvature of the tank jacket 10 and following instantaneous variations in curvature, thereby ensuring a uniform distribution of forces under all load conditions.

Abstract: To enable small or medium-size containers to be directly secured to locking members existing on vehicle loading areas for ISO containers and to be placed in ISO containers or ISO container frames, only one (23) of two fittings (23, 27) provided at opposite container ends is rigidly mounted whereas the other (27) is foldable between an operative position in which it projects beyond the outer dimension of the container, and a rest position in which it is inside the outer container dimension.

Abstract: The bottom structure of small and medium size tank containers includes a pair of longitudinal fork lift channels and a pair of tranverse fork lift channels extending perpendicularly of the longitudinal channels. The transverse channels are defined by gaps between portions of profile bars forming the longitudinal channels. The profile bar portions are equipped with bottom plates which have openings for engagement by locking members provided on the loading platforms of vehicles. Locking plates are further provided at the bottoms of end frames of the tank container, each locking plate having a plurality of further openings for engagement by locking members as commonly provided on road and railway vehicles for ISO containers. A portion of an upper transverse bar of each end frame is formed as a grappler arm pocket provided with an upper guide plate. An upper portion of the guide plate forms an eye reinforced by a transverse member for engagement by a crane hook.

Abstract: A tank container includes a cylindrical tank having its one end connected to an end frame 14 by means of an end saddle structure 12. In the area of its other end, the tank 10 is connected to an end frame 13 by means of a saddle structure 11 in such a manner that the tank bottom 20' provided at this tank end projects through the end frame 13. The saddle structure 11 comprises three rings interconnected partly by welding and partly by screwing, with the innermost ring being welded to the cylindrical portion of the tank envelope.

Abstract: In order to secure small and medium-size containers having a width of e.g. 2200 mm to locking members as provided at a standard lateral spacing of 2259 mm on vehicle platforms designed for transporting ISO containers, such small or medium containers are equipped with double-fittings (12) each comprising two openings (13) and projecting beyond the width dimension of the container. The center-to-center spacing of the two openings (13) is 280 mm and thus corresponds to the distance of pairs of locking members which are provided on such platforms for engaging adjacent corner fittings of two ISO containers placed behind each other. By the simultaneous coupling to such pairs of locking members, safe securing with better distribution of forces is achieved also for containers that are shorter than the shortest ISO container.

Abstract: A swap tank has transverse bars disposed at the standard spacing of ISO containers and end portions extending beyond the transverse bars. Each end portion has associated with it a base frame structure including the transverse bar and a pair of diagonal struts which extend towards each other and are welded together at the tank end. A support member is welded between the interconnected ends of the diagonal struts and a ring welded to the tank bottom below the tank axis. The support member is formed as an integral bent sheet metal part having two lateral triangular wall elements. To compensate for manufacturing tolerances, the support member may be adjusted by varying the bending angle in such a manner that the free edges of the triangular wall elements extend parallel and flush with the outwardly facing surface of the ring and may be welded thereto.

Abstract: A symmetrical latching plate, which includes a central latching portion having a recess and two lateral hook portions, is used for mutually coupling two back-to-back containers and for simultaneously locking the same to a common twistlock. In the latching position, in which the latching plate extends in parallel to a loading surface accommodating the containers, the twistlock engages in the recess, and the hook portions engage behind web portions respectively provided on either container. In a vertical position, which is pivoted by 90.degree. relative to the latching position, the latching plate can be withdrawn along a bottom framework member of at least one of the containers.

Abstract: An swap tank, which is suited for being used in connection with two different locking modules of ISO container vehicles, includes a bottom frame with two frame portions each of which consists of a lower transverse beam (15) and two longitudinal beams (16) that extend only over part of the tank length. An end ring element (18) welded to each tank end bottom (12) is connected to the transverse beam (15) by triangular saddle piece (23) placed on the transverse beam (15). The longitudinal beam (16) is connected to a reinforcing ring (14) surrounding the tank at its end remote from the transverse beam (15) and to a further reinforcing ring (13) at an intermediate location. The portion of the longitudinal beam (16) between the two reinforcing rings (13,14) serves for engagement by a grappler arm. Outer corner fittings (17) are provided on the underside of the transverse beam (15) at both ends thereof.

Abstract: With due consideration of the cross-sectional dimensions available in ISO containers and of the cold-rolling widths that can be achieved, a pressure-resistant tank may be constructed from two casing portions (10, 11) each prefabricated from two longitudinally welded cold-rolled plates, a bottom tubular longitudinal member (12) and a trough-shaped top longitudinal member (13). The two longitudinal members (12, 13) are interconnected by means of tie rods (14). The top longitudinal member (13) comprises a top shell (15) projecting into the interior of the tank, a tension plate (18) interconnecting the upper edges of the top shell (15), and a section member (19) fitted inbetween the top shell (15) and the plate (18). The relatively wide top shell (15), which is required on account of the aforementioned dimensional reasons, is also used to accommodate the manhole (23) and other tank fittings and forms a spill-over trough therefor, which can be emptied downwards through one of the tubular tie rods (14).

Abstract: A tank container suitable especially for smaller tank volumes comprises two triangular end frameworks (10) each composed of two equal-length legs (11) and a bottom transverse beam (12). The tank (15) can be joined to the framework structures (10) directly via end mounting structures (16) so that a framework base structure can be omitted. The apex of each end framework structure (10) is provided with a fitting (14) for engagement by hoisting equipment. In this way a light-weight framework is obtained. At the same time, it is possible to couple the tank container to the respective hoisting equipment at only two points without any risk of tilting during lifting.

Abstract: In a tank container, the tank (16) which is formed of a plurality of parallel cylindrical shells (17, 18) is connected by saddle structures (19) to a pair of end frames (10). The saddle structures (19) each consist of a U-bar (20) having its legs welded to the respective shell (17, 18) and two L-bars (21, 22) welded to the lower traverse (13) and, respectively, the corresponding corner upright (11, 12).

Abstract: A pressure-resistant tank has a jacket composed of a plurality of parallel extending part-cylindrical shells (10) with any adjacent pair of shells (10) being interconnected by a tubular longitudinal bar (15) extending along the bead area formed between said adjacent shells. Opposite longitudinal bars (15) are interconnected by tubular tie rods (18) which traverse the interior of the tank. Reinforcing pipe sections (20) are inserted into the longitudinal bars (15) in the areas where the tie rods (18) are joined to the longitudinal bars (15).

Abstract: When a transport tank for transporting liquids is to be transported with only a partial load, the slosh forces occurring in this case may be reduced by means of slosh guard elements adapted to be built into the already existing tank. The slosh guard elements comprise strips of material bent generally to .OMEGA.-shape, which are fixed in the region of the opening of the .OMEGA.-shape to rails having cross profile. The rails and the slosh guard elements are dimensioned such that they can be introduced through the manhole provided in the tank outer wall.

Abstract: A container is locked by use of a locking plate (15) which engages a fork-lift opening (12) formed in a lower container frame member (10) and which has a portion (15a) projecting from said opening (12) and formed with a hole (18) for engagement with a twistlock (19). The opening (12) is disposed at an intermediate position of the frame member (10) between the ends thereof, so that the container is secured against tilting about its front and rear edges. The configurations of opening (12) and locking plate (15) are matched to each other such that the container is also locked against transverse movement.

Abstract: A temperature-controlled tank container comprises a heat-insulating jacket (23) surrounding the tank on all sides with a uniform close spacing. The space between the tank and the jacket (23) is subdivided into compartments by reinforcing rings (13), end rings (14), and partition webs (30) which extend on either side of the vertex line. By means of through-holes (37 . . . 42) formed in the reinforcing rings (13) and end rings (14), the compartments communicate with each other so that a temperature-control medium, which is supplied and discharged at one end, flows completely about the tank along a meandering path and through a vertex channel (34) which includes the tank fittings (18).

Abstract: In a tank container, a support member 20, which is inserted between a reinforcing ring 11 of the tank 10 and a lower cross-strut 17 of the container framework is composed of two sheet-metal elements 21, 22 which are bent towards each other and which may be fitted in the spandrel space formed between reinforcing ring 11 and cross-strut 17 and welded to each other in such a way as to result in a central rigid rectangular tube having softer surface elements arranged on the two outer sides for preventing peak stresses.

Abstract: An end mounting between the tank (10) and an end frame (11) of a small or medium size container comprises four tubular sections (21) which are welded with their respective one end edge to the spherically curved main portion (13) of the tank end (12) and with their respective other end edge to a leg (23) of a diagonal strut (20) which is formed by an L-bar and bridges a respective corner of the end frame (11).

Abstract: Medium-size containers with corner fittings (21) that are not in accordance with ISO specifications may be locked to ISO locking elements (25) of the type provided on loading areas of container transport vehicles by means of locking plates (10) movably disposed inside the hollow frame elements (11) of the containers, provided the container frame has a corresponding width. The locking plate (10) has an overall width that corresponds to the clear diagonal dimension of the frame element (11) and is provided on its outer longitudinal edge with cut-outs (12, 13) in the region of which the remaining width of the locking plate corresponds to the clear width of the frame element (11). For locking the container, the locking plate (10) is adapted to be moved so that one (16) of the webs defined by the cut-outs (12, 13) extends outwards through an edge hole (22) that may be formed in the frame element (11) and a further web (18) extends outwards through a corner opening (28) of the corner fitting (21).
