Abstract

The present invention relates to a crane for handling a load hanging on a load cable, comprising a slewing gear for rotating the crane, a luffing gear for luffing up the boom, and a hoisting gear for lowering or lifting the load hanging on the load cable, with a control unit for calculating the actuation of slewing gear, luffing gear and/or hoisting gear, wherein the calculation of the actuation commands for actuating slewing gear, luffing gear and/or hoisting gear is effected on the basis of a desired movement of the load indicated in Cartesian coordinates.
