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： 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.

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.

摘要： An apparatus for conveying thick matter has a drive cylinder for receiving hydraulic fluid, a drive piston, which is arranged in the drive cylinder, a conveying cylinder for receiving thick matter, a conveying piston, which is arranged in the conveying cylinder, and a piston rod, which is fastened to the drive piston for coupling motion together with the conveying piston. The drive cylinder has a rod-side opening for applying pressure to a rod side of the drive piston by way of hydraulic fluid and a crown-side opening for applying pressure to a crown side of the drive piston facing away from the rod side by the hydraulic fluid. A drive pump is designed to generate a drive volume flow having a drive pressure of hydraulic fluid for moving the drive piston. A pump connection is designed for variable connection of the drive pump to the rod-side opening or the crown-side opening for the flow of hydraulic fluid. A sensor is designed for automatic detection of whether the pump connection is connected to the rod-side opening or the crown-side opening. A control unit controls the apparatus in a rod-side operating mode, when the rod-side pump connection is detected, and in a crown-side operating mode, when the crown-side pump connection is detected.

摘要： A hydraulic system having a hydraulic pump, having a plurality of hydraulic loads and having a plurality of load-sensing valves for adjusting the pump performance of the hydraulic pump. An association unit is arranged between the hydraulic pump and the hydraulic loads and in a first switched state defines a first hydraulic path between the hydraulic pump and the hydraulic loads and in a second switched state defines a second hydraulic path between the hydraulic pump and the hydraulic loads. The system comprises a controller, which processes a state value of a hydraulic load as an input variable and which determines a control signal for the switched state of the association unit. The invention also relates to a method for controlling a hydraulic system.
