Abstract
The invention concerns a crane or excavator for traversing a load hanging from a load cable, which is movable in three spatial directions. The crane or excavator has a computer- controlled regulation for the damping of load swings, which contains a path planning module, a centripetal force compensation unit and at least one shaft regulator for the rotating gear, one shaft regulator for the luffing gear and one shaft regulator for the lifting gear.
