Abstract: An actuating drive (2) including a ball screw drive (3) for activating a self-closing, linearly activated fitting (4) and a method of use are provided. While the opening of the fitting (4) with the actuating drive (2) takes place by an electric motor by the ball screw drive (3), a restoring movement is transmitted to the spindle (6) when closing the automatically closing fitting (4). The restoring movement, and thus also a closing movement of the fitting (4), can be at least indirectly decelerated by way of the ball screw drive (3), this being able to protect the fitting (4) and ultimately also the ball screw drive (3) and optionally further components connected to the fitting (4) and/or the ball screw drive (3) from damage, and facilitating a fail-safe function.

Abstract: In order to increase the operational safety of an actuator (1) including an electric motor (2) and a transmission, preferably a non-self-locking transmission (3), a braking device is provided which allows the controlled, self-actuating displacement, by a retarding brake (5), of an actuating element connected to the actuator (1) via the transmission (3). The actuating element can be held in a fixed position by an additional holding device (6), even if the electric motor (2) fails. The actuator can be used to drive heavy sluice gates, in the event of a power failure, in a controlled free-fall operation at a constant rate of fall, or to hold them in a defined position. The holding device and the retarding brake can be combined in a common housing (11) to form a braking module (12) which can be designed to be used modularly with existing motor actuators and transmissions.
