Claim 16:
17. A method comprising:
controlling drive devices of a tower crane subject to dynamic loads during operation for moving one or more crane elements used for traveling a load suspension means along a travel path, the load suspension means attached to a hoist rope running from a trolley displaceable along a boom supported by a tower of the tower crane; and
damping oscillation movements of the load suspension means and/or of the hoist rope resulting from the dynamic loads;
wherein the damping comprises:
determining elastic deformations and movements of the tower and one or more other structural elements of the tower crane in response to being subject to the dynamic loads that occur during operation of the tower crane; and
automatically influencing the movement of one or more of the crane elements via control of the drive devices in response to the determined deformations and movements;

wherein a control apparatus performs the controlling;
wherein an oscillation damping device performs the damping;
wherein a determination means comprising a sensor system including at least one deformation sensor attached to the tower performs the determining;
wherein a control module performs the automatically influencing; and
wherein, while the tower crane is configured to allow the tower and the one or more other structural elements to experience the elastic deformations and movements, the step of dampening dampens the oscillation movements of the load suspension means and/or of the hoist rope resultant from the elastic deformations and movements of the tower and the one or more other structural elements.
