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.
