Abstract A crane, in particular a revolving tower crane, having a hoist rope that runs off from a crane boom and carries a load suspension means; having drive devices for moving a plurality of crane elements and for traveling the load suspension means; having a control device for controlling the drive devices such that the load suspension means travels along a travel path; and having an oscillation damping device for damping oscillating movements of the load suspension means and/or of the hoist rope, wherein the oscillation damping device has an oscillation sensor system for detecting oscillating movements of the hoist rope and/or of the load suspension means and has a regulator module having a closed feedback loop for influencing the control of the drive devices in dependence on a oscillation signal of the oscillation sensor system fed back to the feedback loop, characterized in that the oscillation damping device has a structural dynamics sensor system for detecting deformations and/or dynamic movements in themselves of structural components of the crane; and in that the regulator module of the oscillation damping device is configured to take account of both the oscillation signal of the oscillation sensor system and the structural dynamics signals fed back to the feedback loop that indicate deformations and/or dynamic movements in themselves of the structural components on the influencing of the control of the drive devices.
