Abstract: A lift device includes a base, a retractable lift mechanism, a work platform, and a lift controller. The retractable lift mechanism is moveable between an extended position and a retracted position. The work platform is configured to support a load and is coupled to and supported by the retractable lift mechanism. The linear actuator is configured to selectively move the retractable lift mechanism between the extended position and the retracted position. The linear actuator has an electric motor and an electromagnetic brake. The lift controller is in communication with the linear actuator and is configured to determine the load supported by the work platform based on the actuator force applied to the work platform and the height of the work platform.

Abstract: A fully-electric scissor lift comprises a base, a retractable lift mechanism, a work platform, a linear actuator, and a battery. The base has a plurality of wheels. The retractable lift mechanism has a first end coupled to the base and is moveable between an extended position and a retracted position. The work platform is configured to support a load. The work platform is coupled to and supported by a second end of the retractable lift mechanism. The linear actuator is configured to selectively move the retractable lift mechanism between the extended position and the retracted position. The linear actuator has an electric lift motor. The battery is configured to apply power to the electric lift motor. The fully-electric scissor lift is completely devoid of moving fluids.
