  • transport widths of more than 4 m and transport heights of more than 3 m are no longer or at least not readily transportable on the common traffic routes such as roads, along rail transport and / or on shipping lanes. If a transport vehicle exceeds at least one of the above transport dimensions, this transport must be declared and accompanied as a special transport due to the traffic regulations in Germany, for example, because of excess width. As a result, effort and costs for transport increase considerably.
