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. In some embodiments, a rotating or 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.

A construction vehicle includes a vehicle body defining a first end and a second end. A construction vehicle also includes a guard assembly disposed proximate to the second end of the vehicle body. A construction vehicle includes a mounting assembly removably coupling the guard assembly with the vehicle body. Further, the mounting assembly includes a first mounting structure including a plurality of side plates defining a cavity and a first mounting plate coupled with the plurality of side plates. The mounting assembly also includes a second mounting structure removably coupled with the first mounting structure, the second mounting structure including a second mounting plate and a third mounting plate angularly disposed relative to the second mounting plate. Moreover, the guard assembly is in alignment with the first mounting plate and the second mounting plate for coupling the guard assembly with the mounting assembly.
