摘要： One aspect is an actuator system having a rotatable drive shaft and a parallel axis friction brake engaged with the drive shaft and configured to provide a drag force on the rotatable drive shaft. The parallel axis friction brake further includes a brake housing and a friction assembly that has at least one parallel axis shaft and at least one clip pressed over the at least one parallel shaft in an interference fit. The friction assembly is engaged with the drive shaft and coupled to the brake housing, at least a portion of the friction assembly rotating with the rotatable drive shaft to create the drag force.

摘要： A lift device comprises a base, a retractable lift mechanism, a work platform, a linear actuator, and a descent control mechanism. 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 motor. The descent control mechanism is configured to reduce a speed at which the retractable lift mechanism is moved from the extended position to the retracted position.

摘要： 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.
