An apparatus configured to make ski runs comprising a support structure; a first tiller; at least one tracksetting device; and a connection structure that couples the tracksetting device to the first tiller; the connection structure being configured to allow the free rotation about an axis, such as transverse to the advancing direction, of the tracksetting device with respect to the tiller.

Apparatus for making a cross-country ski run

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.

Device and method for controlling an auxiliary winch assembly for moving a crawler vehicle, in particular a snow groomer, along steep slopes

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.

Crawler vehicle drive system and crawler vehicle comprising such a drive system

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.

Crawler vehicle supporting device and crawler vehicle comprising such a supporting device

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.

Crawler vehicle and relative control method

A ski slope snow grooming method, whereby a ski slope grooming implement is moved in a travelling direction along the snow covering; and coherent-energy beams are projected onto the snow covering to form furrows in the snow covering.

Ski slope snow grooming method and relative implement

A snow groomer, equipped with a winch assembly to aid handling of the snow groomer on steep slopes, has a frame; a user interface; a control unit; and the winch assembly, which has a support structure fixed or connected to the frame, a drum that rotates with respect to the support structure about an axis, a cable fixed or connected at one end to the drum and wound about the drum, an actuator assembly for rotating the drum about the axis, and a sensor for determining the position of the drum about the axis; the control unit being configured to control the cable as a function of the position of the drum and the geometry of the drum.

Snowgroomer including a winch assembly to aid handling of the snowgroomer on steep slopes, and method of operating the winch assembly

A tracked vehicle, particularly a piste grooming vehicle, comprising a chassis frame and at least one sprocket for a track is characterized in that the sprocket has limited movement between a working position&#x2014;in which the sprocket protrudes beyond the chassis frame&#x2014;and a transit position in which the sprocket is located at least partially, preferably totally, within the width of the chassis frame.

Tracked vehicle

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.

Ski slope snow tiller

A cable winch arrangement for a vehicle (), particularly for a piste preparation vehicle (), includes a cable winch () and a cable (), and includes a coupling device (), disposed on the cable (), for coupling to and decoupling from an external anchorage point (), with the arrangement having a means for remote-controlled coupling and/or decoupling of the coupling device ().
