Abstract
An actuator arrangement comprises a first screw shaft, a first nut cooperating with the first screw shaft such that rotation of the first screw shaft causes the first nut to translate thereon, a second screw shaft, a second nut cooperating with the second screw shaft such that rotation of the second screw shaft causes the second nut to translate thereon, and first and second linkages connecting the first and second nuts, respectively, to an output member, rotation of the first and second screw shafts to cause translation of the first and second nuts towards one another causing extending movement of the output member and rotation of the first and second screw shafts to cause translation of the first and second nuts away from one another causing retracting movement of the output member.
