Abstract: A crane system includes crane with a load hook that can be raised or lowered via movable crane elements, and moved within a crane working area by operating drive units associated with the crane elements. The crane system further includes a control unit and a mobile transponder that can be variably positioned in the crane working area, and one or more transmitting/receiving units communicatively coupled to the control unit and configured to receive signals transmitted by the mobile transponder. The control unit is configured to automatically determining the current position of the mobile transponder relative to the load hook and/or a crane element based on the signals received from the mobile transponder, and automatically control the drive units in such that the load hook is automatically moved to the mobile transponder.

Abstract: The present disclosure concerns a crane, in particular a tower crane, telescopic boom crane, harbor crane and the like, with a load hook that can be raised or lowered via movable crane elements, and moved within a crane working area by operating drive units associated with the crane elements. The crane is provided with a control unit with input means to control the drive units. According to the present disclosure, the crane uses a mobile portable target signal transmitter that can be variably positioned in the crane working area, and positioning means for automatically determining the current position of the target signal transmitter relative to the load hook and/or a crane element, and target control means for automatically controlling the drive units in response to a signal from the positioning means, such that the load hook is automatically moved to the mobile target signal transmitter.
