Advanced Transport System for Dangerous Materials Based on New 20-Foot Container with Computable Load Behavior

The newly developed F.H. Timpert freight-securing system is a reusable, elastic system consisting of support trays serving to secure drums with dangerous goods in a 20-foot ISO box container during road and rail transport. The geometry and material of the support trays can be varied within broad limits so that the system can be adapted to the various levels of demand in the transport regulations for dangerous goods corresponding to the classification of the dangerous goods. In the following, this is shown in detail on the basis of restraining devices for steel drums used for the transport of lowlevel radioactive wastes. To date, steel drums with dangerous freight have often been anchored by tension straps to secure the load in the container. The tension straps were applied around several steel drums and attached at the bottom to the anchoring points in the container. Securing the load in this way often proved to be disadvantageous in practice, since steel drums do not have any special anchoring facilities, such as eyelet attachments, shackles, or clips, for reliable restraining with tension straps. Due to the inevitable vibrations and movements of the steel drums in the container during transport, the tension straps may slip and thus fail to fulfill their task of securing the load.
