A rotary lifting device comprises an actuator shaft, a linear motor and a rotary motor for moving and rotating the actuator shaft about the longitudinal axis thereof. The rotary motor has a hollow rotor, through which the actuator shaft extends and which is kinematically coupled to the actuator shaft in terms of rotation. The linear motor has an armature coaxially arranged with respect to the actuator shaft and kinematically coupled to the actuator shaft at a first longitudinal end thereof. A step-down gear is arranged at a second longitudinal end of the actuator shaft and is capable of being moved in an axial direction relative to the rotary motor. The step-down gear is kinematically coupled to the actuator shaft at the drive side, both with respect to axial movement of the actuator shaft and with respect to rotating movement of the actuator shaft.
