Abstract:
1. An articulated connection of a first traction rod to a second traction rod for bracing a crane jib, each of the first and second traction rods comprising: a metallic tubular body having a longitudinal extent and a tube cross-section and at least one end with a wall thickening, wherein an outside diameter of the wall thickening is greater than an outside diameter of the tube cross section and a transition region from the tubular body to the wall thickening is unitary and constructed to be free of projections and low on notch effects, and a coupling element detachably connected to the at least one end of each metallic tubular body of the first and second traction rods in absence of a material connection therebetween, with the coupling element of the first traction rod constructed for articulated connection to the coupling element of the second traction rod with a bolt extending transversely through openings in both the coupling element of the first traction rod and the coupling element of the second traction rod, wherein the at least one end with the wall thickening is dimensioned such that a fatigue strength corresponds to a calculated full load capacity of the tube cross-section.
