Abstract
A method for automatic control of the position of a burden suspended in a main wire of a crane, where the burden is connected with at least two tag lines which respectively is connected to a number of winches. The control of the position and rotation of the burden is performed by actuators on the respective winches which perform ease off/tightening of the respective tag lines from signals of at least tone measuring unit with signal transmitter located on the burden measuring angles. A central monitoring- and control unit performs control of rotation and position of the burden by multiple transmitting of compensatory control signals to relevant actuators for tag lines and the crane main wire. Guiding and control of the position of the burden is possible even when subject external random impacts, as wind and sea. Further the method is useable in positioning the burden in correct mounting position.
