Abstract
A fully electric lift device includes a base assembly, a lift assembly, a platform assembly, tractive elements, an energy storage device, and a control system. The lift assembly is coupled with the base assembly and is driven by an electric linear actuator for a lifting function. The platform assembly is positioned at a top of the lift assembly and can be raised or lowered as the lift assembly performs the lifting function. The tractive elements are rotatably coupled with the base assembly and can be driven by an electric wheel motor to perform a driving function. The control system includes a controller that operates the electric wheel motor and the electric linear actuator to perform the driving function and the lifting function using power drawn from the energy storage device. The lift assembly and the tractive elements use only electrical energy to perform the lifting and driving functions.
