A movable apparatus for creating an outdoor ice rink and a method of using it comprising a spray head configured to apply a water spray from a height sufficient to maintain a stable vertical spray head orientation and periodically repositioning it until a desired ice rink s formed.

A tracked vehicle for finishing the ground, in particular a snow grooming vehicle for finishing ski slopes; the vehicle comprising: a main supporting frame configured for supporting side tracks and an upper cabin; at least one working assembly, such as a tiller assembly, frontally and posteriorly coupled to the main frame and configured for finishing the ground during the movement of the vehicle; a lifting device for the working assembly and configured for selectively switching the working assembly between a first lowered working position, wherein it is in contact with the ground, and a second raised inactive position, wherein it is not in contact with the ground; at least one hydraulic stabilizing device acting on the working assembly and configured so that in the first lowered working position it does not inhibit the movement of the working assembly with respect to the main supporting frame, and in the second raised inactive position it stabilizes the working assembly with greater resistance to movement with respect to the main supporting frame.

A ski resort management system comprising: a data acquisition system that receives data from telemetry systems of the lift systems, of the snow generators and of the snow groomers of the ski resort; a processing station; mass storage units, containing a system database fed by the data acquisition system; and a display interface, accessible from operator terminals. The data acquisition system stores data and signals from the lift systems, the snow generators and the snow groomers in the system database. The processing station enables setting a mode of the display interface for alternatively displaying data relative to each lift system, to each snow generator or to each snow groomer, or to display, in an aggregated form, data relative to all the lift systems, all the snow generators and all the snow groomers.

A snow tooth for a snow tiller for preparing the snowpack of ski slopes; the snow tooth comprising a first projection having a first height and a second projection having a second height, the first height and the second height; the snow tooth being shaped so as to be connected to a rotating shaft and have, in use, a main direction of rotation. The first projection is arranged along the snow tooth so that, in use, the first projection sinks into the snowpack before the second projection in particular when, in use, the snow tooth is attached to a shaft of the snow tiller and the shaft rotates in the main direction of rotation.

A ski dolly includes a frame, a first ski, a second ski, a first coupler fastened to the frame, and a second coupler fastened to the frame. The frame may include a tongue that couples to an upper member. Descending from a first side of the upper member may be a first leg and from a second side of the upper member may be a second leg. Spanning between the first leg and the second leg may be a panel. Further, interposed between a lower surface of the upper member and an upper surface of the panel may be a panel member that receives the second coupler. The ski dolly is coupled to a snowmobile or tracked vehicle at one end and is coupled to a trail grooming device at an opposite end.

A computer-aided method for maintaining a snow piste, according to which state data relating to the snow piste are captured in a time-dependent manner. The state data include snow constitution data which depend on a constitution of a piste surface of the snow piste, a prediction model for the state of the snow piste at at least one point in time in the future is calculated from the captured state data, and information relating to the prediction model is output.

An ice leveling system involves a laser receiver mountable on an ice conditioning head of an ice resurfacing machine below a top-most portion of the ice resurfacing machine and at least two laser projectors that project laser light in a plane below a level of the top-most portion of the ice resurfacing machine. The at least two laser projectors are mountable adjacent to an ice surface and are positionable around the ice surface so that the laser receiver when mounted on the ice resurfacing machine always receives the laser light from at least one of the at least two laser projectors during an ice leveling operation. At least one of the at least two laser projectors is height adjustable to align the laser light plane projected by the height adjustable laser projector with the laser light plane of others of the at least two laser projectors.
