ABSTRACT OF THE DISCLOSURE A multisection crane boom having a fly and jib assembly attachable thereto is disclosed herein. The fly section and jib section of the assembly are pivotally interconnected at adjacent ends through a freely pivoted link so that the jib section can be pivoted from the position extending generally parallel and below the fly section to a usable position where- in the longitudinal axes of the two sections are aligned with each other or coincident at the interconnected ends. Cable means are utilized for holding the jib section in an extended position on the fly section and the cable means are capable of having the jib in end-to-end or angular relation with respect to the fly section. The fly section also has a lug thereon which prevents attachment of the cable means when the fly sec- tion is at an angular position with respect to the main boom.
