b) a continuous transit weigher (11) in flow communication with the conveying pipe segment and having a funnel and a fixed section of pipe segment; c) a large lifting pipe segment (13) in flow communication with the fixed section of pipe segment and having a cable winch (15) and slack cable monitor; d) a resting ring (16) and filling level monitor on the lifting pipe segment at the telescopic conveying pipe outlet; e) an annular flushing device (12) on one of the pipe segments; f) one of flushing device components partly fixedly mounted, flushing pipes or a flushing ball with a flange mounted on one of the pipe segments; g) tubing in flow communication with one of the pipe segments for compressed air and pipelines for fully demineralized water and waste water; h) closing, controlling valves; and i) a local control unit for filling and flushing processes and operating the valves. ### Claim 2 (depends on 1) The conveying device according to claim 1, wherein the telescopic conveying pipe has a flange, and a sensor is provided on the flange of the telescopic conveying pipe. ### Claim 3 (depends on 1) The conveying device according to claim 1, wherein the device is constructed to minimize dead space. ### Claim 4 (depends on 1) The conveying device according to claim 1, wherein the telescopic conveying pipe is disposed on a mobile work platform adapted for transport of the telescopic conveying pipe to different filling sites on the stage, the mobile work platform including a lifting/transporting device (10, 15) for positioning of the telescopic conveying pipe at different docking devices on a stage. ### Claim 5 (depends on 4) The conveying device according to claim 4, wherein the lifting/transporting device (8) is supported by an electric drive. ### Claim 6 (depends on 4) The conveying device according to claim 4, wherein the lifting/transporting device is adapted for secure removal of a floor cover on the work platform. ### Claim 7 (depends on 4) The conveying device according to claim 4, wherein the work platform is movable by electric drives or movable drives. ### Claim 8 (depends on 4) Conveying device according to claim 4, characterized in that a common position of the light spots of positioning lasers supports a positioning operation of the work platform. ### Claim 9 (depends on 4) The conveying device according to claim 4, further comprising at least two positioning lasers adapted to create light spots on a floor, such that a common position of the light spots serves as indicia of appropriate operational positioning of the work platform. ### Claim 10 (depends on 1) The conveying device according to claim 1, wherein a slack cable enquiry serves as an indicia to begin a filling process. ### Claim 11 (depends on 1) The conveying device according to claim 1, wherein the initial lifting pipe (10) is radially displaceable. ### Claim 12 (depends on 1) A method for cleaning the conveying device according to claim 1, wherein a flushing program automates a flushing process and selects flushing components for the introduction of water from the top downwards. ### Claim 13 (depends on 12) The method for cleaning the conveying device according to claim 12, wherein the annular flushing device cleans the outer side of the telescopic pipe.
