Abstract: Artificial snowmaking equipment, preferably indoor, comprises a refrigerating cylinder rotating about a longitudinal axis; movement means configured to rotate the refrigerating cylinder; a cooling unit configured to cool an outer side wall of the refrigerating cylinder to a freezing temperature; a water supply system configured to wet at least part of the outer side wall so as to create a layer of ice thereon; at least one scraper device configured to scrape at least part of the ice layer so as to obtain an artificial snow fall. In particular, the refrigerating cylinder internally has a gap extending along an inner surface thereof opposite the outer side wall. The gap is connected to the cooling unit so as to receive a flow of a refrigerating substance to be conveyed therein to cool the outer side wall of the refrigerating cylinder.

Abstract: A fluid-jet emitting machine, particularly a firefighting machine, comprises a fluid-jet emitting device, a transport vehicle, lifting members and a control device. Each lifting member comprises an actuator constrained to the transport vehicle and at least one idler wheel adapted to engage a rail of a track. The actuators are configured to move the respective wheels between a non-operative position, in which the wheels are distanced from the respective rail, and an operative position, in which the wheels are arranged in contact with the respective rail. The control device is operatively associated with the actuators to activate the passage of the wheels from the non-operative position to the operative position so that during movement along a track and in said operative position, the wheels prove to be pressed against the respective rail, exerting a force such as to reduce only part of the pressure exerted by the movement means of the vehicle on the track.

Abstract: A method for managing the production of an artificial snowmaking plant having a plurality of snowmaking apparatuses arranged along a ski slope, comprising the operating steps of: comparing historical forecast values (VSP) of a parameter with respective one or more historical values of the realistically measured weather parameter (VSR1,2,3) at said one or more snowmaking apparatuses arranged in said predefined geographical area; determining future forecast values (VFP) of said parameter as a function of a historical difference value (D1,2,3) determined at one or more apparatuses so as to determine one or more realistic future forecast parameter values (VFR1,2,3) at each snowmaking apparatus on which the historical difference value (D1,2,3) has been determined.

Abstract: A nucleation nozzle for forming freezing nuclei for devices for making artificial snow, starting from a jet of pressurised liquid, comprising a compressed air duct having an inlet opening and an outlet opening. A first stretch of the compressed air duct has a cross section which decreases in the flow direction of the compressed air, from the inlet opening to the outlet opening. The first stretch is followed by a second stretch having a cross section which increases in the flow direction of the compressed air from the inlet opening to the outlet opening. There is provided at least one water duct having an inlet opening and an outlet opening. The water duct is separate from the compressed air duct. The outlet opening of the water duct is positioned close to the outlet opening of the compressed air duct.
