청구항

1. An actuator arrangement comprising a pair of screw actuators driven from a common motor through respective drive shafts connected to respective outputs of a differential gearbox, and a protection arrangement comprising a tie arrangement connected across the outputs of the differential gearbox and to each corresponding respective driveshaft, wherein the tie arrangement is responsive to a difference in the torques applied to the drive shafts and arranged to avoid the continued application of drive to one of the screw actuators in the event of the occurr...
