The invention shows a rotary positionable installation, such as a wind power, having a tower (11), and an apparatus carrier supported on the tower so as to be rotatable about its axis and rotary positionable by means of an azimuth drive unit, particularly a housing (2), including a frequency adjusting unit (18, 19 27; 40, 42, 46; 66, 74) for the natural yawing frequency of the swinging system of the following components: apparatus carrier (2), azimuth drive unit and tower (1) by adjusting the torsion (rotation) spring constant by means of one of the components and/or the connection between at least two of the components of the swinging system. In this manner, the adjustment of the natural yawing frequency is made possible in a simple manner in respect to construction as well as operation.
