Crane or crane-like handling device with a positioning system

摘要

The crane has a transponder (55), which is fixed at a predetermined position against the crane. A transponder (59) is fixed at a load, which is shifted from the crane. A hook is fixed to the load or a target to which the load is transferred. An evaluation unit (53a) is coupled with a transmitting and receiving mechanism, and is arranged to determine the distance between the transponder (55) and a jack based on the transponder signal and the base transmitter signal.
