Abstract

The invention relates to a crane jib for a crane, having a longitudinal axis and an imaginary contour line that extends in a transversal plane relative to an axis of symmetry in an at least approximately mirror-symmetric manner. The contour line has an at least approximately arcuate section between a center that is equally interspaced from the first and second point of intersection on the axis of symmetry and the first point of intersection, and a first straight section is tangentially contiguous thereto in the direction of the second point of intersection. The imaginary extension of the first straight section in the direction of the second point of intersection intersects the axis of symmetry and forms an acute angle therewith. A second straight section is tangentially contiguous to the approximately arcuate section in the direction of the first point of intersection and extends up to the axis of symmetry and forms an angle of less than 90 degrees with the axis of symmetry in the first point of intersection in the interior of the surface enclosed by the contour line.
