Abstract: A snow grooming vehicle comprising a support frame; an engine; two tracks mounted on opposite sides of the support frame itself, coupled to and driven by the engine; and comprising a first plurality of bristles arranged in a portion of the snow grooming vehicle adjacent to the track so as to capture the snow collected on the track.

Abstract: A control device configured to control a winch assembly having a supporting structure has a guide, which engages a cable extending along a path in a sliding manner, and is configured to follow the movements of the cable crosswise to the path; a first control chain activated by movements of the guide in a first direction crosswise to the path; and a second control chain activated by movements of the guide in a second direction crosswise to the first direction and the path.

Abstract: 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.

Abstract: A tracked vehicle comprising: a first and a second track; a generator assembly configured to generate mechanical power; a group of work devices coupled to the generator assembly; a first and a second drive wheel coupled to the first and to the second track, respectively, and to the generator assembly; a user interface configured to receive commands from an operator; and a control unit connected to the user interface to receive commands from the operator; the control unit being configured to: measure an amount of time elapsed between a command sent by the operator and a subsequent command sent by the operator; and set the tracked vehicle to a blocked state if the amount of time measured is greater than a first time interval threshold.

Abstract: A ski slope snow tiller configured to travel in a travelling direction along the ski slope; the snow tiller having two supporting structures hinged to each other about a hinge axis; two shafts housed respectively in the supporting structures and configured to rotate about respective rotation axes crosswise to the travelling direction; tools fitted to the shafts; and at least one further tool connected at least to a shaft and located between the two supporting structures.

Abstract: A crawler vehicle drive system, in particular for a crawler vehicle configured to groom ski slopes, having: a drive wheel rotating about a first rotation axis; an idle wheel rotating about a second rotation axis parallel to the first rotation axis); and a track looped around the drive wheel and the idle wheel, and comprising a plurality of belts made of an elastomeric material and a plurality of metal grousers fixed to the belt; wherein at least one belt has at least one continuous toothed strip extending along the inner face of the belt and configured to mesh with the drive wheel.

Abstract: A supporting device for a crawler vehicle configured to groom ski slopes, is mounted between a rear wheel and a front wheel, resting along the inside of a traction portion of the track, and has a plurality of rollers much smaller in diameter than the rear wheel; a belt looped around the rollers; and a structure configured to support the rollers and to push the rollers and the belt against the inside of the traction portion of the track.

Abstract: A crawler vehicle having a first and second track driven by a first and second drive wheel respectively; an internal combustion engine; a mechanical power transmission assembly extending from the internal combustion engine to the first and second drive wheel; an electric power transmission assembly; a mechanical power connection configured to transfer energy between the mechanical power transmission assembly and the electric power transmission assembly; and at least one mechanical power transmission configured to transfer energy between the electric power transmission assembly and the mechanical power transmission assembly; the electric power transmission assembly extending from the mechanical power connection to the mechanical power transmission.

Abstract: A control method of a tracked vehicle having a track belt and configured to advance the tracked vehicle provides for acquiring the driving speed of the tracked vehicle; acquiring the speeds of the tracks with respect to the tracked vehicle; calculating a range of expected values of traveling speed as a function of speed of the track; and varying the speed of the track when the traveling speed of the tracked vehicle is outside the range of expected values.

Abstract: A ski slope snow tiller configured to travel in a travelling direction along the ski slope; the snow tiller having two supporting structures hinged to each other about a hinge axis; two shafts housed respectively in the supporting structures and configured to rotate about respective rotation axes crosswise to the travelling direction; tools fitted to the shafts; and at least one further tool connected at least to a shaft and located between the two supporting structures.

Abstract: A ski slope snow tiller having a frame connected to a tractor movable in a travelling direction; a shaft crosswise to the travelling direction and fitted with tools for working the snow cover; a casing surrounding the shaft; a mat towed over the surface of the snow cover, behind the casing; and a guard located at least over the casing and the mat, to prevent snow accumulating.

Abstract: Device for preparing the landing plate of a ski-jump, guide and deflection rollers being arranged, provided with clearance, in the vicinity of the take-off platform of the ski-jump, which rollers receive a cable, the ends of which, arranged along the landing plate, can be connected to two snow vehicles.
