摘要： An apparatus for the output of a fluid process material, in particular a process material in the form of concrete, mortar or adhesive, has a distributor boom comprising a plurality of boom arms, connected to each other at joints, having a process material delivery line formed by a plurality of pipe segments, which are preferably joint-connected to each other by pipe bends and rotating couplings. The delivery line is guided along the individual boom arms and fixed thereto. A tool, which is received on the distributor boom, has a device for the output of the process material. The tool has a buffer vessel, which receives the process material from the process material delivery line, and an output element for the output of the process material, fed from the buffer vessel, at an output location.

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： A device for a distribution mast includes a line and a line section mounting. The line has a mast line section and a loose rotational line section, and the rotational line section is rotatably connected to the mast line section. The line section mounting has a loose rotational holding element and a rotary bearing, and the rotational holding element keeps the rotational line section at a distance from the mast line section. The rotary bearing is designed to be supported by a mast segment for the distribution mast and for rotatably connecting the rotational holding element to the mast segment and defines a circle, the line being guided through the circle.

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： A method for operating a construction-material and/or viscous-material pump for conveying construction material and/or viscous material has the steps of: a) determining a required value of a power or of a size of the motor system, corresponding to the power, for moving the conveying piston, b) setting, on the basis of the required value, a speed value of the motor system in such a manner that a power and/or speed reserve value between an operating point, wherein the operating point is defined by the required value of the power or of the size and the speed value, and a characteristic curve of the motor system, wherein the characteristic curve is defined by maximum values of the power or of the size and speed values, wherein maximum values are different for different speed values at least in sections, is greater than or equal to a reserve limit value.

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： The invention relates to a method for detecting and verifying a working position of a mobile concrete pump, said method comprising the steps: a) setting up and at least partially supporting the concrete pump at a set-up position; b) detecting position-related data of a working position, wherein the working position is located in a region of a surface to be concreted which is remote from the set-up position; c) comparing the position-related data with a theoretical working area resulting from the set support; and d) outputting a signal as to whether the working position can be operated. This makes it possible to set up or support a mobile concrete pump in the most optimal manner possible. The invention also relates to a method for determining a suitable support setting, a measurement device, and a mobile concrete pump.

摘要： An extruder head for extruding a strand of building material for 3D printing of a structural part. The extruder head has an extruder nozzle with a discharge opening for discharging the strand of building material out of the extruder head in a discharge direction, a specification element designed to be variably adjustable for variably settably specifying at least a part of a strand cross section of the strand of building material being discharged, and a setting apparatus designed for variably setting the at least one specification element. The setting apparatus is designed and arranged such that the extruder head, in a first extent direction which differs from the discharge direction, extends below the discharge opening, in the case of a maximum opening height, by at most the maximum opening height, and/or, in at least one second extent direction differing from the discharge direction, extends to the side of the discharge opening, in the case of a maximum opening width, by at most the maximum opening width.

摘要： The invention relates to a thick material pump having a first delivery cylinder, a second delivery cylinder and an additional cylinder. The additional cylinder serves for bridging a transition between the first delivery cylinder and the second delivery cylinder. The thick material pump comprises a movable tube portion which forms a connection between the first delivery cylinder and an outlet of the thick material pump in a first state and which forms a connection between the second delivery cylinder and the outlet of the thick material pump in a second state. The movable tube portion comprises a switchable closure which is arranged between an inlet end of the movable tube portion and the additional cylinder. The thick material pump according to the invention makes it possible for a uniform material flow to be delivered in the direction of the pump outlet.
