Abstract
A crane housing for a leg encircling crane to be mounted onto a slew bearing includes an annular base component, two support components, and a frontal component, each having bulkheads. The support components are connected to the annular base component at respective lateral sides of a front segment thereof. The frontal component is connected to the front segment of the annular base component, between the two support components such as to interconnect these. The two support components and the frontal component together form a front torsion box, which provides torsional rigidity. The load of the boom, as applied on the support components, subjects the base component via the torsion box to a torsion that is distributed over the front segment of the base component.
