  • Patent number: 8025167
    Abstract: The present invention shows a crane control of a crane which includes at least one cable for lifting a load, wherein at least one sensor unit is provided for determining a cable angle relative to the direction of gravitational force. Furthermore, there is shown a crane control for driving the positioners of a crane which includes at least one first and one second strand of cables for lifting the load, with a load oscillation damping for damping spherical pendular oscillations of the load, wherein first and second sensor units are provided, which are associated to the first and second strands of cables, in order to determine the respective cable angles and/or cable angular velocities, and the load oscillation damping includes a control in which the cable angles and/or cable angular velocities determined by the first and second sensor units are considered. Furthermore, a corresponding crane and a method are shown.

  • Patent number: 7850025
    Abstract: A method for controlling the orientation of a crane load is described, wherein a manipulator 416 for manipulating the load is connected by a rotator unit to a hook suspended on ropes 410 and the rotational angle ?L of the load is controlled by a control unit using the moment of inertia JL of the load as most important parameter. The control unit is an adaptive control unit wherein the moment of inertia JL of the load is identified during operation of the crane based on data obtained by measuring the state of the system.
