A crane housing having a substantially cylinder-shaped circumferential wall with a lower section and lower end mounted to a slew bearing of substantially the same diameter includes a boom support structure to support an inner end of a pivotal boom arranged at a front side of the crane housing. The boom support structure includes at least two box elements of each of which an end portion overlaps with and is integrated with the upper section of the circumferential wall. Oblique strengthening ribs are mounted onto and integrated with a side of the circumferential wall and extend from a respective box element end portion in an oblique downwards direction towards the lower end of the wall.
