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 (s) in an at least approximately mirror-symmetric manner, the contour line intersecting the axis of symmetry (s) in a first and a second point of intersection (S<sub>1</sub>, S<sub>2</sub>) and the contour line having an extremal point (E) with a maximum distance (e) from the axis of symmetry (s) between the first point of intersection (S<sub>1</sub>) and a center (M) that is equally interspaced from the first and the second point of intersection (S<sub>1</sub>, S<sub>2</sub>). The distance (d) of the contour line from the axis of symmetry (s) is smaller or equal 0.8 times the maximum distance (e) at approximately a fourth of the distance (D) between the first and the second point of intersection (S<sub>1</sub>, S<sub>2</sub>), starting from the second point of intersection (S<sub>2</sub>).
