  • Patent number: 11919749
    Abstract: The present invention relates to a crane, in particular to a revolving tower crane, having a load suspension means attached to a hoist rope, drive devices for moving a plurality of crane elements and for traveling the load suspension means, a control apparatus for controlling the drive devices such that the load suspension means travels along a travel path, and an oscillation damping device for damping oscillation movements of the load suspension means, wherein said oscillation damping device has a control module for influencing the control of the drive devices in dependence on oscillation-relevant criteria. It is proposed not only to take account of the actual oscillation movement of the rope per se in the oscillation damping measures, but also the dynamics of the steel construction of the crane and its drivetrains.

  • Patent number: 11014789
    Abstract: A construction machine, in particular in the form of a crane, cable excavator or similar, comprising an electronic control device for controlling and/or detecting operating parameters, in addition to at least one drive device for moving a functional element, especially a load take-up means. The functional element of the construction machine is guided in the desired direction by the exertion of manipulation forces on the functional element, or on a component fastened thereto, or the functional element is moved manually in a designated direction, this motion then being assisted by the drives of the construction machine. If the functional element is manually pressed or pulled in a designated direction and/or rotated, or if this is at least attempted, these motion attempts are detected and converted into a corresponding positioning motion of the construction machine.
