[origin: US6085445A] PCT No. PCT/EP97/00932 Sec. 371 Date Mar. 29, 1999 Sec. 102(e) Date Mar. 29, 1999 PCT Filed Feb. 26, 1997 PCT Pub. No. WO97/32085 PCT Pub. Date Sep. 4, 1997A piste-preparation device for preparing a half-pipe comprises at least one tool adjustably mounted on a piste vehicle, and lateral members which are laterally disposed relative to the tool and can essentially be assigned to side walls of the half-pipe. To prepare a half-pipe even in cases where the surface is hard and, at the same time, to remove a large amount of material, in particular from the half-pipe side walls, each lateral member comprises removal means designed with removal tools which can move substantially transversely to the direction of travel of the piste vehicle.
