# Scissor lift descent control systems and methods

## Abstract

A fully-electric lift vehicle comprises a base, a battery, a scissor lift movable between an extended position and a retracted position, a work platform the scissor lift, a linear actuator including an electric motor powered by the battery, an electromagnetic brake coupled to the electric motor; and a manual release coupled to the electromagnetic brake so that, in the event of a power failure, actuation of the manual release enables the scissor lift to descend toward the retracted position. The electric motor is configured to act like a generator and reduce a descent speed of the scissor lift during the descend toward the retracted position.
