For streets, canals, houses or bridges, everywhere that is built up, great piles of sand, gravel, stone or asphalt will often be needed. These so-called bulk goods will be transported by lorries with special bodies. Names such as three-way tipper, rear tipper or dump truck are the best known in these parts. In the USA a dump truck or dumper is also a tipper, but which only tips out or empties the transported materials at the back. Many different manufacturers of body superstructures supply dumper bodies for multiple-axle lorry chassis made by the firms Peterbilt, Mack, Freightliner or Kenworth. Most of the dumpers are made of aluminium and, how could it be otherwise in the land of unlimited possibilities, naturally they are attractively painted or all in chrome. The Kenworth W900 with chrome superstructure presents itself in its finest Sunday suit , made by Truckweld of Oregon, USA. As far construction vehicles of this kind are concerned in the USA one finds innumerable types of design and construction.
