摘要： A crane, in particular a revolving tower crane or a bridge crane, and a method for controlling such a crane, having a hoist cable, which extends from a crane boom and carries a load-receiving means, drive devices for moving crane elements and displacing the load-receiving means, a control apparatus for controlling the drive devices such that the load-receiving means travels along a travel path, and a pendulum damping device for damping pendulum movements of the load-receiving means, wherein the pendulum damping device has a pendulum sensor for detecting pendulum movements of the hoist cable and/or of the load-receiving means and a controller component having a closed control circuit for influencing the control of the drive devices depending on pendulum signals that are indicated by pendulum movements detected by the pendulum sensor and are returned to the control loop.

摘要： The invention relates to a crane, in particular a rotary tower crane, comprising a lifting cable configured to run out from a crane boom and comprises a load receiving component, drive devices configured to move multiple crane elements and displace the load receiving component, a controller configured to control the drive devices such that the load receiving apparatus is displaced along a movement path, and a pendulum damping device configured to dampen pendulum movements of the load receiving apparatus and/or of the lifting cable. The pendulum damping device comprises a pendulum sensor system configured to detect pendulum movements of at least one of the lifting cable and the load receiving component and a regulator module comprising a closed control loop configured to influence the actuation of the drive devices depending on a pendulum sensor system signal returned to the control loop.
