INCREASING USE OF ALUMINIUM IN LORRY SUPERSTRUCTURES

ALUMINIUM OEKAR I PAABYGGNADER

After 25 years' development, aluminium is now a viable competitor to steel and timber for lorry superstructures. Its low weight and ease of forming, and also its low elastic modulus, are an advantage, but its low strength and high price have been an obstacle. All-aluminium lorry platforms are now common. Superstructures wholly enclosed in aluminium are more common in central Europe than in Sweden, where plastics are more usual, but floors are made of aluminium. Interchangeable load carriers must be durable, require little maintenance and have low weight, and there is a lot of scope here for aluminium. Fast trains demand low-weight construction, and aluminium makes possible weight savings of about 50%. The advanced passenger train of BR has chassis, floor construction, walls and roof in aluminium. The weight of the 21-M carriage body is 5.2 tons. The 200 km/h train of German rail, which is already in service, is constructed on the same principle. Hovertrains for speeds up to 500 km/h must have a low-weight construction, and aluminium is used in designs now under trial.
