Abstract

The link joins together two sections of the jib of a crane, and comprises one or more link members (9), pivoting at opposite ends on the first and second sections. It allows the two sections (5,7) to pivot in relation to each other through 360 deg., the pivoting movement being effected by an actuator, typically a hydraulic ram (13). The jib sections can be tubular, there being a link member on each side, and stops can also be mounted on the sections so that these stop in positions parallel to each other. The rams can be so mounted that their pivot axes (13b) on the outer jib section are at a lower level than those on the inner section and than those of the link members, when the two sections are in line with each other.
