The AHM 800 R is a formation rehabilitation machine for plain track with two excavating chains and integrated material recycling.  New ballast is placed in a subsequent working pass.  The machine performs the following stages of work in one operation:

  • Removal of the upper layer of ballast
  • Crushing this ballast and return
  • Producing the finished sand-gravel mixture while checking the moisture content
  • Excavation of the remaining ballast material and the upper layer of the subsoil
  • Smoothing the new earth formation
  • Installation of protective materials such as geotextiles, Styrofoam, plastic sheeting or geo-meshing.
  • Installation of the formation protective layer
