Abstract
The invention relates to a method for the transfer of a load hanging at a load rope of a crane or excavator comprising a slewing gear, a luffing mechanism and a hoisting gear comprising a computer-controlled regulator for the damping of the load oscillation which has a trajectory planner, a disturbance observer and a state regulator with a pre-control, wherein the working space is first fixed by selection of two points, with one of the two points being fixed as the destination point by direction presetting by means of the hand lever and with the nominal speeds for the slewing gear and the luffing mechanism being preset by the hand lever signals.
