20100307033 | ROTARY SNOW TILLER FOR GROOMING SKI SLOPES - A rotary snow tiller for grooming the snow covering of ski slopes, and which advances in a traveling direction along the ski slope, and has a frame; and a shaft which is rotated with respect to the frame about a first axis crosswise to the traveling direction, and is fitted with tools, each of which extends along a second axis crosswise to the first axis, and is selectively adjustable about the second axis with respect to the first axis. | 12-09-2010 |
20110000107 | ROTARY SNOW TILLER FOR GROOMING SKI SLOPES - A rotary snow tiller, for grooming the snow covering of ski slopes, which advances in a traveling direction along the ski slope, and has a frame; and a shaft fitted with teeth and rotated with respect to the frame about an axis crosswise to the traveling direction; each tooth being fitted movably to the shaft and selectively adjustable in length with respect to the shaft. | 01-06-2011 |
20110005106 | ROTARY SNOW TILLER FOR GROOMING SKI SLOPES AND RELATIVE OPERATING METHOD - A rotary snow tiller, for grooming the snow surface of ski slopes and designed to advance in a travelling direction, has a frame; a shaft rotating about an axis transverse to the travelling direction, and having teeth for breaking up the snow surface; a further shaft located behind the shaft, rotating about a further axis transverse to the travelling direction, and having further teeth for further breaking up the snow surface; and a finish mat located behind the further shaft. | 01-13-2011 |
20110005107 | ROTARY SNOW TILLER AND SKI SLOPE GROOMING METHOD - A rotary snow tiller, for grooming the snow covering of ski slopes, which advances in a traveling direction along the ski slope, and has a frame; a shaft fitted with teeth and rotated with respect to the frame about an axis crosswise to the traveling direction; and an actuating device for imparting a reciprocating movement to the shaft with respect to the frame. | 01-13-2011 |
20120305321 | SNOW GROOMER AND RELATIVE CONTROL METHOD - A ski slope snow groomer having a frame; two wheel assemblies on opposite sides of the frame; two tracks wound respectively about the two wheel assemblies; a variable-configuration shock absorber assembly connected to the wheel assemblies and the frame and configured to adjust the wheel assemblies; and a control assembly configured to acquire a signal indicating an operating state of the snow groomer, and to adjust the shock absorber assembly as a function of the operating state signal. | 12-06-2012 |
20130138304 | SNOW GROOMER AND RELATIVE CONTROL METHOD - A snow groomer having a frame; an attachment connected movably to the frame; a hydraulic assembly having an actuator configured to position the attachment, and a valve configured to control the actuator; a variable-flow pump configured to supply the hydraulic assembly; and a control system configured to calculate the total flow rate demand of the hydraulic assembly, and configured to control the variable-flow pump as a function of the total flow rate demand, so delivery by the variable-flow pump equals the total flow rate demand. | 05-30-2013 |
20130185963 | HITCH DEVICE FOR CONNECTING A GROOMER VEHICLE AND A SKI SLOPE SNOW GROOMING IMPLEMENT, AND CONTROL METHOD EMPLOYING SUCH A HITCH DEVICE - A hitch device for connecting a groomer vehicle having a first frame extending along a first axis, and an implement, in particular a rotary snow tiller, for grooming the snow covering of ski slopes and having a second frame extending crosswise to and symmetrically with respect to a second axis. The hitch device has an arm hinged to the first frame about a third axis perpendicular to the first axis, and about a fourth axis perpendicular to the first and third axis; a first actuator for adjusting the position of the arm about the third axis with respect to the first frame to lift and lower the implement; at least one second actuator for adjusting the position of the arm about the fourth axis with respect to the first frame; a movable coupling movable between the arm and one of the first and second frame; and a third actuator for adjusting the position of the arm in a plane crosswise to the fourth axis. | 07-25-2013 |
