Abstract: A supporting leg for a working machine that has a mast includes a hollow body, which is composed of two web plates arranged at a distance from each other and two flange plates, which connect the web plates to each other and are arranged at a distance from each other and are connected to the web plates by welds, and a supporting foot protruding downward from the hollow body. The web plates each have two substantially vertically arranged broad sides and two substantially horizontally arranged narrow sides that connect the broad sides to each other. The flange plates each have two substantially horizontally arranged broad sides and two substantially vertically arranged narrow sides that connect the broad sides to each other. The flange plates each lie against broad sides of the web plates facing each other via the narrow sides of the flange plates and the narrow sides of the web plates are exposed and form lower and upper contact surfaces of the hollow body.

Abstract: This disclosure relates to a work machine with a chassis, with a mast block which is mounted on the chassis and has a rotary head which can be rotated about a vertical axis of rotation, and with a mast which has at least two mast arms, wherein each of the mast arms, with the exception of a last mast arm which has a free end, is pivotably connected, starting from a first mast arm, to the respectively following mast arm by means of an articulation, and wherein the first mast arm is mounted on the rotary head so as to be pivotable about a horizontal pivot axis. According to this disclosure, at least one chassis-mounted supporting device is provided which has a supporting surface on which a component of the articulation or a component of one of the articulations is supported.

Abstract: This disclosure relates to a distribution boom for stationary or mobile viscous material pumps, comprising at least one boom arm having a box profile. The boom arm has two side walls which are arranged at a distance from one another and which are connected to one another by means of two transverse walls which are arranged at a distance from one another. Each side wall has a lead-through opening for a conveying line. Provision is made according to this disclosure for there to extend between the side walls a tube which is fixedly connected thereto and which opens by way of the tube ends thereof into the lead-through openings. Between the tube ends and the adjacent side wall there is arranged a respective flange which projects in an encircling manner over an outer border of the respective tube end and is welded both to the tube end and to the side wall in question.
