Abstract
A crane boom extension or jib is held on the nose of the boom by a single fixed length self-adjusting cable loop which extends around an arcuate guide attachable at several different locations to an inclined plane mounting bracket on the jib near its outer end. The mere repositioning of the guide on the inclined plane mounting bracket allows the jib to assume several different angularly offset positions relative to the axis of the boom without other adjustments. The inclined plane mounting bracket establishes the plane in which the cable loop lies in all adjusted positions of the jib. The arrangement is convenient, safe and simplified.
