Traction rod for bracing a crane jib
Abstract:
The invention relates to a traction rod for bracing a crane jib, comprising a metallic tubular body and coupling elements which are connected to both ends thereof in an articulated connection of the traction rods among each other by means of bolts. According to the invention, the tubular body and the coupling elements can be detachably connected to each other, dispensing the need for a bonded connection, wherein the region of the connection is dimensioned in such a manner and is low on notch effects that, by calculation, the entire load capacity of the tube cross-section can be exploited with respect to a highest possible fatigue strength.
