Abstract
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.

Method for producing a distal boom segment of an articulated boom of a large manipulator wherein a box profile is produced by welding an upper belt and a lower belt to lateral web plates, wherein before welding the upper belt, lower belt and web plates, at least one bending running essentially in the longitudinal direction of the distal boom segment is introduced into at least one sheet metal section of the upper belt, lower belt and/or web plates, wherein 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, wherein the at least one sheet metal section comprises a first sheet metal section and a second sheet metal section, the first sheet metal section having a first thickness, the second sheet metal section having a second thickness that is greater than the first thickness.
Articulated boom of a large manipulator having a plurality of boom segments connected to one another via articulated joints, wherein a distal boom segment of the plurality of the boom segments comprises 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 with respective welds,
- wherein at least one of the web plates and/or 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,
- wherein 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,
- wherein at least one of the web plates and/or the upper belt and/or the lower belt comprises a first sheet metal section and a second sheet metal section, the first sheet metal section having a first thickness, the second sheet metal section having a second thickness that is greater than the first thickness,
- wherein the first sheet metal section and the second sheet metal section are connected to one another at a transition,
- wherein the first sheet metal section comprises a bending running along a longitudinal direction of the distal boom segment.
