Abstract:
Apparatus for hardening the surface of a snow and/or ice covered trail which includes apparatus for travel over the snow and/or ice covered terrain that includes means to remove entrained air from snow and/or ice particles proximate to the apparatus; means for redistribution of the dispersed snow and/or ice laterally and axially with respect to the apparatus incident to movement of the apparatus after dispersing has occurred; and means for compacting snow and/or ice redistributed in the means for redistributing to increase the hardness of the snow and/or ice that has been redistributed.
Abstract:
An unmanned mobile device for treating a snow covered surface having transport means adapted to the movement on snow and/or ice is disclosed. The device has compressing means of the snow for exerting a compression force on the snow in order to increase the specific weight thereof and/or varying means of the temperature of the surface of the snow.
Abstract:
Piste grooming vehicle and clearing blade for a piste grooming vehicle. The piste grooming vehicle has a clearing blade arranged at the front and includes a middle part and two side parts swivellably movable relative to the middle part, a setting arrangement for adjusting the middle part and/or the side parts and at least one manually operable actuating element arranged inside a cab for operating the setting arrangement. An electronic control unit is connected between the actuating element and the setting arrangement and operates the setting arrangement with a timed sequence of control commands for achieving at least one control function for the side parts and/or the middle part from an initial position to an end position preset by the control function.

Abstract:
A snow removal system includes a tool having a blade and a boom. The boom includes a first end portion connected to the blade and a second end portion configured to be releasably, pivotally mounted to a loader arm of a vehicle.
Abstract:
The invention relates to a piste grooming vehicle with a point of application for cable forces that is associated with a cable winch, the point being at a distance from a yaw axis of the piste grooming machine, at least one control device being provided and being operatively connected to at least one control for automatically compensating at least one cable torque that can be applied by a cable traction force of the cable winch in relation to the yaw axis.
Abstract:
A support mount for a receiver in an ice resurfacing machine, an ice resurfacing machine, a system for making an ice surface level with a desired horizontal plane and its kits of each of them. A receiver is mounted on a support mount for maintaining an ice resurfacing machine level with a desired horizontal plane comprising a mast post that retracts within a structure mounted on the conditioner. The receiver detects a light beam being transmitted along a plane parallel to a desired horizontal plane. The position of the mast post relative to the structure is constrained such that the height of the receiver in a transport position is vertically retracted to permit the ice resurfacing machine to pass under obstacles while entering or leaving an ice surface and in an operative position is extended to a height whereby a light beam emitted by a transmitter along a plane parallel to the desired horizontal plane may be detected. At all times the mast post remains away from contact with the ice surface. Rather, the height of the receiver above the top of the conditioner is maintained constant while in the operative position to permit calibrated and level resurfacing of the ice surface level with the desired horizontal plane.
Abstract:
A snow track maintenance system is described herein including a frame extending along an axis which is oriented along a direction of displacement, a mounting assembly secured to the frame for mounting the frame to a motorized vehicle so as to be trailed therefrom along the direction of displacement, and a leveller mounted to the frame so as to be pivotable relatively to the direction of displacement. Other equipments may further be provided to the maintenance system, including a snow regenerator mounted to the frame along a first longitudinal axis generally perpendicular to the direction of displacement, and a snow compactor mounted to the frame upstream from the snow regenerator. The system can be used for the maintenance of alpine ski tracks and cross-country ski tracks, even in an underbrush trail, and allows setting a track on any type of snow.
Abstract:
An ice-removing device for removing ice from a ground surface. The ice-removing device comprises a frame and an ice cutting mechanism. The ice cutting mechanism is attached to the frame and is adapted to spin on a first axis oriented transversally to the frame. The ice cutting mechanism is operative to cut a plurality of parallel strips in the ice. Optionally, the ice-removing device further comprises at least one ice crushing mechanism, which is also attached to the frame, behind the ice crushing mechanism. The ice crushing mechanism is adapted to spin on a second axis that is non-parallel to the first axis. Both the ice cutting mechanism and the ice crushing mechanism are operationally positioned to contact the ice. In another embodiment the ice-removing device is adapted to be mounted to a mobile support.
Abstract:
A collapsible snow groomer designed to be provided as a partial kit where the buyer purchases two runners separately. Along with the runners the kit comprises all materials necessary to assemble a snow groomer for use on personal snow trails. The collapsible snow grooming device of the present invention includes and comprises: a tubular front spreader, two L-angle cross blades, a square central joiner tube, four angle grooming blades and all required fasteners. All grooming hardware members are thus strategically attached to one edge of each runner and to each other at one edge, thereby allowing to flip the whole assembly over to drag it where grooming is not desired.
