    • The invention discloses, inter alia, a thick matter conveying system (10), comprising a thick matter pump (16) for conveying thick matter, a thick matter distributor boom (18) for distributing the thick matter to be conveyed, the thick matter distributor boom (18) having a boom arrangement (40) comprising at least two boom arms (41), a substructure (30) on which the thick matter distributor boom (18) and the thick matter pump (16) are arranged, the substructure (30) comprising a supporting structure (31) for supporting the substructure (30) having at least one horizontally and/or vertically movable supporting leg (32), the supporting structure (31) having a stability region with a re-securing threshold and with an upper limit defined by a maximum stability parameter, and the at least one supporting leg (32) being able to be re-secured, a receiving unit (11) for receiving at least one item of operating information, a processing unit (12) for determining a stability parameter of the thick matter conveying system (10) depending on the at least one item of operating information received, and a control unit (13) for outputting a first control signal if the determined stability parameter of the thick matter conveying system (10) lies above the re-securing threshold, outputting of the first control signal suppressing re-securing of the at least one supporting leg (32).

    • The invention relates to, inter alia, a thick matter conveying system (10) comprising a thick matter pump (16) for conveying a thick matter; a thick matter distributing mast (18) for distributing the thick matter to be conveyed, said thick matter distributing mast (18) having a rotary mechanism (19) which can be rotated about a vertical axis and a mast assembly (40) comprising at least two mast arms (41); a substructure (30) on which the thick matter distributing mast (18) and the thick matter pump (16) are arranged, said substructure (30) comprising a support structure (31) for supporting the substructure (30) by means of at least one horizontally and/or vertically movable support leg (32); a sensor unit (11) comprising at least one sensor for detecting a piece of operating information; and a processing unit (12) for determining a stability parameter of the thick matter conveying system (10) on the basis of the at least one detected piece of operating information and for ascertaining an intended operation of the sensor of the sensor unit (11), said sensor detecting the at least one piece of operating information. If the processing unit (12) does not ascertain an intended operation of the sensor, the processing unit (12) is designed to determine the stability parameter on the basis of an extreme value of the operating information to be detected by the sensor instead of the detected piece of operating information.

    • The invention relates to a boom-arm segment, comprising an upper chord (33), a lower chord (34) and two side parts (35, 36) connecting the upper chord (33) and the lower chord (34). The boom-arm segment (30) comprises a hinge connection (62) which defines a pivot axis (74) for a pivot connection between the boom-arm segment (21) and an adjacent structure (20), wherein: the pivot axis (74) is located below the plane (63) of the lower chord (34); a transition piece (64) is located between the lower chord (34) and the hinge connection (62), and the connection (65) between the transition piece (64) and the lower chord (34) is spaced apart from the adjacent end (61) of the lower chord (34); the transition piece (64) is enclosed between a first reinforcement part (40) and a second reinforcement part (70) which laterally adjoin the transition piece (64); the reinforcement parts (40, 70) each have a lower edge (69) which extends from the hinge connection (62) to the lower chord (34); and the lower edges (69) enclose an angle (68) with the plane (63) of the lower chord (34) that is smaller than the angle (67) which the transition piece (64) encloses with the plane (63) of the lower chord (34).
