KIT FOR THE CONVERSION OF A HEAVY EQUIPMENT VEHICLE
The invention relates to a kit 10 for the conversion of a heavy equipment vehicle 12 from a diesel-hydraulic configuration to an electro-hydraulic configuration. The kit comprises: an electric power supply unit 14; a plurality of electric motors 16; a control interface unit 18; and a control unit 20. In the kit 10 according to the invention, the electric power supply unit is suitable for: being connected to an external energy source 22, receiving energy from the external source, accumulating a quantity of energy, and after being disconnected from the external energy source, supplying electric power to at least some of the electric motors. At least one of the electric motors is mechanically coupled to a hydraulic pump 24; at least one of the electric motors is mechanically coupled to a mechanical gear 26; at least one of the electric motors is mechanically coupled to a cooling fan 28. The control interface unit is suitable to be handled by an operator and to generate electric signals relating to the selective operation of some electric motors; and the control unit is suitable for selectively operate some electric motors on the base of the electric signals received from the control interface unit and on the base of a pre-loaded logic. The invention also relates to a heavy equipment vehicle 12 comprising the kit 10.
Described is a mobile plant for the aspiration, treatment, suppression and depuration of fumes and/or dust and/or gaseous mixtures coming from processing of metals or other materials, and in particular from the processing of the metals with flame cutting, by means of which even small production units or larger production units but with limited quantities of materials to be processed or processed in an occasional manner with significant emission of fumes and/or dust can prevent the dispersion into the atmosphere of the fumes and/or dust and can treat the fumes and dust; according to this invention, the mobile plant for the aspiration, treatment, suppression and depuration of fumes and/or dust and/or gaseous mixtures coming from processing of metals or other materials comprises two separate units which integrate and act in conjunction with each other: a removable and transportable hood which is movable from a processing area to a standby area, under which the processing is performed which cause fumes and dust, and which has the purpose of preventing the dispersion of the fumes and dust into the atmosphere, a mobile and transportable plant for the aspiration and treatment of the fumes and dust present in the hood, the two parts being connected by connectors.

DEVICE FOR RECOVERING HEAT AND FUMES FROM SLAG RESULTING FROM THE STEEL PRODUCTION CYCLE
Described is a device for recovering heat and fumes from slag resulting from the steel production cycle which allows the heat emitted by the slag during the cooling to be used without the need to collect the slag in tubs which must then be transported to the cooling surface and tipped in order to discharge the slag; at the same time, this device allows the fumes and consequently the heat and the pollutants which the slag emits during the tipping and the time on the cooling surface to be conveyed and treated.
