  • a half pipe has a previously known slope preparation device of the type mentioned above, for example from the magazine "Internationale Seilbahn-Rundschau" 5/1993, pages 42 to 44 is known, on the side of an implement arranged side plates. These are shaped so that the manufacture and processing the side walls of the half pipe with a competition profile is possible.
  • the invention is therefore based on the object, a slope preparation device type mentioned to improve in that a half pipe even with hard Surface can be prepared and at the same time a larger amount of material, can be cleared in particular from the side walls of the half pipe.
  • each side part has a substantially transverse to the direction of travel of the snow groomer Movable broaching tools trained broaching device for processing has a slope surface of the half pipe.
  • Broaching tools can remove material from the side walls of the half pipe in larger sizes Quantity to be cleared.
  • the material can be cleared even when it is standing Snow groomer take place, for example, to make the half-pipe more intense at this point to edit.
  • the broaching tools are designed so that they also a can work harder slope surface.
