This kind of "stiff leg"?

A stiff-leg crane for use in handling loads in the erection of buildings and the like, including a base rotatable 360.degree. on a bearing, a vertical mast rigidly mounted at a lower end at the center of rotation of the base, a boom pivoted at a foot end along one end of the base, boom support and load handling lines from the top of the mast to the boom, a pair of adjustable lay leg mast braces for boom and mast support from either the crane base or the structure being erected by the crane, and means for securing the lower free ends of the lay legs to either the base or the structure being erected. The lay legs are adjustable both in length and the angle between the lay legs and the mast. Additionally the lay legs are fully rotatable 360.degree. about the mast and may swing between the mast and the boom for relocation from one side of the mast to the other without interference with the boom or the boom support and load handling lines. The lay legs are securable to the crane base for jumping the crane and when handling loads close to the crane base. Sills are connectible between the crane base and the lower free ends of the lay legs when structural rigidity requires.
