[origin: EP1090875A1] The jib has telescopic profiled sections, which are each formed of an upper and a lower (5) shell, where the nominal wall thickness of the upper shell is less than or equal to that of the lower shell. The shells are welded together. At least one section has a shell with a cross-section formed from two outer, spaced, thin metal plates with an intermediate space (9), which may be partly or completely filled with a metal foam (10).
