  • Patent number: 12252866
    Abstract: An electric loader is provided with a plurality of independently driven wheels. For example, a four-wheeled electric loader includes four independently operated wheels, each directly coupled to a dedicated electric motor. A fifth independent electrical motor powers the lift arm and/or any attachments coupled to an auxiliary hydraulic. A central forced-air system supplies pressurized air to each independent electric motor to cool the electric motor during operation. In some embodiments, the auxiliary electric motor powers the fan and/or air conditioner of the central forced-air system. A lever and/or electric brake may be applied to an axle of the electric motors. A pivotable battery panel locks a plurality of battery cells to provide a central source of power, counter-weight the loader arm, and rotate away to provide the operator access to an internal cavity of the cab.
