Abstract (en)

[origin: WO9918292A1] The invention relates to a device (1) for forming half-pipes which prepares and/or maintains a half-pipe (2). The inventive device comprises at least one clearing device (4) which can be mounted on a skidozer (3) and can pivot relative to said skidozer. In an operation position, the clearing device can be assigned to at least one side wall of the half-pipe (2). In order to thus improve said device (1) such that a half-pipe (2) having uniform contouring can be quickly and easily constructed with as little work as possible independent of the course and changes in cross-section of said half-pipe, the invention provides that the clearing device (4) can additionally be displaced perpendicular to the driving direction of the skidozer (3) and is mounted so as to pivot around an essentially vertical axis relative to the skidozer.
