Abstract
A fully-electric lift device includes a base; a retractable lift mechanism, a work platform, an electric linear actuator configured to selectively move the retractable lift mechanism between an extended position and a retracted position, and a controller. The linear actuator includes an electric motor. The controller is in communication with the electric motor and configured to receive a lift command, monitor a required torque for the electric motor based on the lift command, and selectively inhibit the lift command based on the required torque.
