A rotary snow tiller (1), for grooming the snow covering (M) of ski slopes, which advances in a travelling direction (D) along the ski slope, and has a frame (2); and a shaft (3) fitted with teeth (12) and rotated with respect to the frame (2) about an axis (A1) crosswise to the travelling direction (D); each tooth (12) being fitted movably to the shaft (3) and selectively adjustable in length with respect to the shaft (3).
Abstract:
A hitch device (1) for connecting a groomer vehicle (2) having a first frame (4) extending along a first axis (Al), and an implement (3), in particular a rotary snow tiller, for grooming the snow covering (M) of ski slopes and having a second frame (7) extending crosswise to and symmetrically with respect to a second axis (A2). The hitch device has an arm (10) hinged to the first frame (4) about a third axis (A3) perpendicular to the first axis (Al), and about a fourth axis (A4) perpendicular to the first and third axis (Al, A3); a first actuator (11) for adjusting the position of the arm (10) about the third axis (A3) with respect to the first frame (4) to lift and lower the implement (3); at least one second actuator (12) for adjusting the position of the arm (10) about the fourth axis (A4) with respect to the first frame (4); a movable coupling (14) movable between the arm (10) and one of the first and second frame (4, 7); and a third actuator (17) for adjusting the position of the arm (10) in a plane crosswise to the fourth axis (A4).
Abstract:
A cable transportation system with at least one haul cable has a supporting structure (4) with a tubular portion (9) defining an axis of rotation (A); a pulley (5) extending about the axis of rotation (A); and a bearing assembly (14), which is connected to the pulley (5) and the tubular portion (9) to allow the pulley (5) to rotate about the axis of rotation (A) with respect to the supporting structure, and has a first and second bearing (17, 18) arranged concentrically and in series, so as to ensure rotation of the pulley (5) about the axis of rotation (A) and with respect to the supporting structure (4) by means of at least the first or second bearing (17, 18).
Abstract:
A track for a snow groomer (1) has a number of grousers (10) spaced apart, extending crosswise to the travelling direction (D) of the track, and each having a gripportion (15) for gripping the terrain, and a blunt edge (10a) opposite the grip portion (15). A chain (12) is connected to the blunt edges (10a) of the grousers (10) so as to be engaged, in use, by a drive sprocket (7) of a snow groomer (1).
Abstract:
A spacer device (4; 39), for a cable transportation system (1; 35) having at least one supporting cable (2; 36) and a pull cable (3; 37), has a frame (6; 41); couplings (7, 8; 44) connected to the frame (6; 41) and fixed to the supporting cable (2; 36); a first guide roller (9; 45) which supported in rotary manner by the frame (6; 41), is located beneath the pull cable (3; 37), and has a first groove (23; 57) engaged by the pull cable (3; 37); and a second guide roller (10; 46) which is located on top of the pull cable (3; 37), has a second groove (25; 59) engaged by the pull cable (3; 37), and is supported elastically by the frame (6; 41), so as to be pressed onto the pull cable (3; 37) and the first guide roller (9; 45).
