Abstract (en)
[origin: US2020298298A1] An articulated boom of a large manipulator includes a plurality of boom segments connected to one another via articulated joints. At least one of the boom segments has a welded assembly forming a box profile in which an upper belt and a lower belt are connected to one another via lateral web plates. At least one of the web plates, the upper belt, and/or the lower belt is formed at least by one sheet metal section, which has at least one bending running essentially in a longitudinal direction of the boom segment. The at least one bending ends at a distance from an end of the sheet metal section so that the end of the sheet metal section is unbent.
