Loading crane controller with user worn remote control input and dispaly device

An operating device for a loading crane, the operating device comprising:

• a crane controller for controlling actuators of the loading crane based on control commands, and for evaluating sensor signals from sensors of the loading crane and for generating sensor data based on the sensor signals;
• an input device spatially separate from the crane controller for allowing input of control commands for the crane controller;
• and a signaling device spatially separate from the input device and configured to be worn on a body of a user, wherein the crane controller has a first telecommunication device for exchanging data signals with the input device, wherein the data signals delivered by the crane controller include the sensor data, wherein the input device has a second telecommunication device for exchanging data signals with the first telecommunication device, wherein the data signals delivered by the input device include control commands, wherein the input device has a transmitting device for delivering the data signals, wherein the signaling device has a receiving device for receiving the data signals delivered by the transmitting device and a displaying device for displaying audio data and/or image data, wherein the signaling device transmits the audio data and/or image data to the user, wherein the crane controller, the input device, and the signaling device are configured in one of the following manners:
• (i) such that the data signals delivered by the crane controller include sensor data, the input device outputs the sensor data to the signaling device via the transmitting device, and the signaling device has a processor configured to generate the audio data and/or image data based on the sensor data, or (ii) the input device has a processor configured to generate the audio data and/or image data based on the sensor data delivered by the crane controller, and the input device delivers the audio data and/or image data via the transmitting device to the signaling device, or (iii) the crane controller has a processor configured to generate the audio data and/or image data based on the sensor data and to output the audio data and/or image data via the first telecommunication device and the second telecommunication device to the input device, and the input device delivers the audio data and/or image data to the signaling device via the transmitting device, wherein the signaling device is configured to superimpose the image data on at least a part of a visual field of the user or to fill at least a part of the visual field of the user with the image data.
