OPERATION MONITORING FOR A THICK MATTER CONVEYING SYSTEM

Disclosed is, inter alia, a thick matter distributor mast (18) for distributing a thick matter to be conveyed by means of a thick matter pump (16), having a slewing gear (19) which can be rotated around a vertical axis at a maximum rotating speed; a mast assembly (40) having at least a first mast arm (41) and a second mast arm (42), wherein the first mast arm (41) is connected to the slewing gear (19) at a proximal end of the mast assembly (40), and wherein the mast arms (41, 42) each have a maximum operating range; a conveying line (17) which extends across the mast assembly (40) and comprises a proximal end, which is connectable to an outlet (28) of a thick matter pump, and a distal end, wherein the distal end of the conveying line (17) transitions to an end hose (45) at a distal end of the mast assembly (40); a receiver unit (11) for receiving at least one item of operational information; a processing unit (12) for determining a currently permissible operating range of the first mast arm (41) and the second mast arm (42) respectively and/or for determining a currently permissible slewing gear speed, each depending on the at least one received item of operational information; and a control unit (13) for limiting the operating range of the corresponding mast arm (41, 42) to the respective currently permissible operating range if one of the determined currently permissible operating ranges of the first mast arm (41) and the second mast arm (42) is smaller than or equal to the respective maximum operating range, and/or to limit the rotating speed of the slewing gear (19) if the determined currently permissible rotating speed is less than or equal to the maximum rotating speed.
