Patent ID: 7831333

Claim:
A method for the transfer of a load hanging at a load rope of a crane or excavator having at least a slewing gear to rotate the crane or excavator, a luffing mechanism to right or incline a boom and a hoisting gear to raise or lower the load suspended at the rope, a computer-controlled regulator for damping load oscillation which has a trajectory planner, a disturbance observer and a state regulator with a pre-control, the method comprising the following steps: fixing a working space by selection of two points including a first point and a second point; fixing the second point as a destination point by direction presetting by means of a hand lever; presetting of nominal speeds for the slewing gear and luffing mechanism by hand lever signals, the load being freely movable in the whole working space and not bound to a specific trajectory, wherein the load moves from the first point to the second point, and during the movement the preset nominal speeds adjust the trajectory of the load.
