Abstract (en)
[origin: WO2021228501A1] The invention relates to a method for operating a lifting device, wherein the lifting device has a holding part for holding an object and has a cable, which can be at least partially wound on a cable drum, wherein the cable drum can be driven by a drive, wherein the drive has a first sensor, wherein a first position of the holding part can be determined from the values captured by the first sensor, wherein a second sensor is disposed on the lifting device, wherein a second position of the holding part can be determined from the values captured by the second sensor, wherein in a first time period a first difference is determined from the first position and the second position, wherein in a second time period a second difference is determined from the first position and the second position, and wherein an action is triggered if the magnitude of the divergence between the first difference and the second difference exceeds a permissible extent of deviation.
