Abstract

An actuator having an output slidable between extended and retracted positions is provided. The actuator includes a primary module having a power drive, power screw rotatable by the power drive, and a nut operable to translate rotation of the power screw to linear motion of the nut across the power screw. The actuator includes a secondary module having a power drive, a shaft rotatable by the power drive, a power screw, and a nut. The power screw is slidably coupled to and rotatable by the shaft, and coupled to the output. The nut is coupled to the power screw and is operable to slide linearly across the shaft by rotating through the nut. Both the primary nut and secondary power screw are operable to move the output to the extended position or the retracted position depending on the rotational direction of the primary power screw and secondary power screw.
