  • Patent number: 9156634
    Abstract: A system and method are disclosed, which can detect and process a position of at least one storage space device moving a bulk material. A first storage space device can have a gantry having two gantry legs, each of the two gantry legs supported on a linearly displaceable foot element. The system can include at least one first non-contact distance sensor, which is fitted on one of the two foot elements to measure a first relative distance between the one foot element and a first fixed reference point. A second non-contact distance sensor is fitted to the other of the two foot elements in order to measure a second relative distance between the other foot element and a second fixed reference point, and an evaluation unit is configured to determine rotation of the first storage space device about a central vertical axis and control the movement of the foot elements.

  • Publication number: 20140067194
    Abstract: Exemplary embodiments are directed to a method for detecting and tracking the position of a mobile transferring device/loading device of a bucket-wheel excavator or bucket chain excavator. The bucket-wheel excavator or bucket chain excavator includes an extraction device having a pivotable superstructure, which has inclinable cantilever, a track-drivable substructure, and a transferring device having a loading cantilever and renders conveyed material through a bench conveyor. An open-loop/closed-loop control device establishes the pivot angle and the inclination of the loading cantilever of the transferring device according to the signals of a plurality of sensors.
