摘要： A boom system for a concrete-delivery device includes a plurality of booms which are pivotably interconnected. At least one of the booms has a recess along its length, the recess configured to at least partially receive an adjacent boom when the boom system. is in a retracted position. Side walls of the boom are extended to define the recess in the form of a channel. The recess may have a depth greater than or equal to a height of the adjacent boom so that the adjacent boom is received within the recess when the boom system is in the retracted position. Alternatively, the recess may have a depth less than a height of the adjacent boom so that the adjacent boom is only partially received in the recess when the boom system is in the retracted position.

摘要： A boom-arm segment for a concrete pump, having 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 side parts (35, 36) each comprising a lower edge portion (43) adjacent to the lower chord (34) and a central portion (44) arranged between the lower edge portion (43) and the upper chord (33). The central portions (44) are at a greater distance from one another than the lower edge portions (43). The boom-arm segment (30) comprises an articulation connection (37) with an articulation surface (12) which defines a pivot axis (74) for a pivot connection between the boom-arm segment (21) and an adjacent structure (20), the articulation surface (12) being at least partially arranged below the plane (63) of the lower chord (34). The articulation connection (37) is connected to the central portion (44) of the first side part (35) via a first connecting support (40), the first connecting support (40) extending beyond the lower edge portion (43) of the first side part (35) without being connected to the lower edge portion (43) of the first side part (35). The invention further relates to a method for producing a boom-arm segment of this type.

摘要： 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.

摘要： The invention relates to a boom arm for mobile concrete pumps and to a mobile concrete pump. The boom arm, having a first and second end, wherein at least one elbowed section, in which the main bending loads which occur during proper use act as torsional loads, is provided between the first and the second end of the boom arm, is made from a fiber composite material, wherein beyond the elbowed region the height of the boom arm in cross-section is greater than the width of the boom arm in cross-section and in the elbowed region the width of the boom arm in cross-section is greater than or equal to the height of the boom arm in cross-section. A concrete pump with a placing boom, arranged on a substructure, comprising at least two boom arms, at least one of which is designed according to the invention.

摘要： This disclosure relates to a drivable working machine, including a vehicle, a concrete placing boom that can be rotated on a vehicle-fixed carrying structure by means of a slewing gear, and a plurality of supporting legs arranged on the carrying structure for supporting the carrying structure in a working position. A compensation device is provided to compensate a rotational deflection of the carrying structure from the working position. The compensation device has a sensing unit for sensing the rotational deflection and acts on at least one supporting leg by means of an associated actuator to reduce the rotational deflection.

摘要： 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).

摘要： A distribution boom for a concrete pump comprises at least a first and a second boom arm, wherein the first and the second boom arm are connected to one another via a joint and are pivotable relative to one another via the joint about a pivot axis, and a concrete delivery line is provided along the boom arms. The joint connects the first and the second boom arm offset to one another so that the load-bearing structures of each of the two boom arms intersect a separating plane running perpendicular to the pivot axis between the first and the second boom arm only in the joint, wherein a hydraulic cylinder is arranged on one boom arm and connected to the other boom arm via coupling rods so that the two boom arms can be pivoted relative to one another by the hydraulic cylinder about the pivot axis of the joint.
