SLEWING CRANE AND METHOD FOR ALIGNING A SLEWING CRANE

摘要

Slewing crane (1) with a vertically running vertical axis (5), a boom (8) projecting from the vertical axis (5), a drive for rotating the boom (8) about the vertical axis (5), a status monitoring system which determines a wind load, in particular internal forces, stresses, strains, shear forces, tilting moments and torsional moments of the slewing crane (1), and a processing unit which calculates a preferred direction for fixing the boom (8) from the wind load. Also disclosed is a method for aligning a slewing crane (1) of this type. To improve the alignment of the boom (8) on slewing cranes (1) which have been shut down, it is proposed that the slewing crane comprises measurement elements (14, 16) for receiving local measured values of the wind load.
