Definitions

  • the invention relates to a slipform paver according to the preamble of claim 1.
  • slipform pavers are needed to Making road surfaces from concrete.
  • Known slipform pavers have a tractor that consists of a Machine frame and four undercarriage consists of different work facilities for distributing and Wear smooth the concrete.
  • the slipform pavers often have to be converted, depending on the required scope of the renovation work takes two to three days to remodel.
  • slipform pavers have already been developed are whose machine frames are telescopically widened can be (WO95 / 28525).
