A power-operated actuator comprises an electric engine, kinematic chains of working and rapid movements, a control system and co-axially mounted coupling and screw mechanism. The kinematic chains of working and rapid movements comprise gears that are located in a cylindrical drum; the input and output gears of said kinematic chains are located coaxially and intermediate shafts are located in the drum housing along the circular arc of the drum. The drum body is mounted on bearings and is equipped with a brake and a clutch being a part of the control system. |
