Abstract
A tracked vehicle comprising an electric machine assembly, a first and a second track coupled to the electric machine assembly, and an electric connection device, connectable to a power supply apparatus outside the tracked vehicle and connected to the electric machine assembly to exchange electrical energy with the power supply apparatus during the operation of the tracked vehicle.
Claims21
A snow groomer comprising:
- an electric machine assembly;
- at least one track coupled to the electric machine assembly;
- a snow grooming working device connected to the electric machine assembly;
- and
- an electric connection device releasably connectable to a moveable power supply apparatus outside the snow groomer, said electric connection device connected to the electric machine assembly to exchange electrical energy with the power supply apparatus during operation, and the electric connection device comprising a shutdown switch configured to disconnect an electric cable responsive to the electric cable having a mechanical tension that is outside an operating range of mechanical tensions.
2 more elements
A power supply apparatus configured to power a snow groomer inside a work area, the power supply apparatus comprising:
- a supply system configured to be releasably connected to the snow groomer which includes an electric machine assembly, at least one track coupled to the electric machine assembly, and an electric connection device connected to the electric machine assembly and configured to exchange, via an electric cable, electrical energy with the supply system during operation of the snow groomer;
- at least one conductive element which extends along a path;
- and
- a slider supported by the at least one conductive element and coupled to the at least one conductive element to move along the path.
1 more element
A snow groomer handling system within a work area, the snow groomer handling system comprising:
- a snow groomer including an electric machine assembly, at least one track coupled to the electric machine assembly, a snow grooming working device connected to the electric machine assembly, and an electric connection device connected to the electric machine assembly, the electric connection device including a shutdown switch configured to disconnect an electric cable responsive to the electric cable having a mechanical tension that is outside an operating range of mechanical tensions;
- and
- a power supply apparatus configured to power the snow groomer inside a work area, the power supply apparatus comprising a moveable supply system comprising at least one conductive element which extends along a path and supports a slider configured to move along the path, the moveable supply system configured to be releasably connected to the electric connection device of the snow groomer to exchange, via the electric cable, electrical energy during operation of the snow groomer.
