Abstract
A crane comprises a mobile vehicle having an upper frame rotatably mounted on a lower frame thereof. A boom has its rearward end pivotally mounted on the upper frame and a doubleacting hydraulic cylinder is pivotally interconnected between the upper frame and the boom to selectively raise and lower the same relative to ground level. A jib has its rearward end pivotally attached to a forward end of the boom by an elongated slot connection which permits the jib to be moved between a stored position in offset relationship adjacent to the boom and an extended position forwardly of the boom wherein the longitudinal axes of the jib and boom are parallel relative to each other.
