Abstract (en)

[origin: WO2020094770A1] A method for weathervaning a crane (1) which has a boom (3) which can rotate about a vertical axis (5), a slewing gear motor (7) and a slewing gear service brake (8) for securing the boom (3) in a rotational position with a securing torque in the crane mode, wherein in the case of a crane which has been decommissioned, the boom is braked against rotation with a decommissioned mode braking torque which is less than the specified securing torque in the crane mode, wherein the decommissioned mode braking torque is applied by a slip clutch (10) in the form of a hysteresis clutch or hysteresis brake which is preferably arranged between the slewing gear brake (8) and the slewing gear drive (7) or between the slewing gear drive (7) and an output gear (11).
