Abstract
A stowable luffing jib provides easy installation to add luffing capabilities to a crane. The stowable luffing jib comprises a base trunnion, a jib assembly, and a cable strut. The base trunnion is secured to the boom assembly and can be selectively placed into a stowed position and a deployed position. While the base trunnion is in the stowed position, the base trunnion is secured along the boom assembly substantially parallel with and adjacent to the boom assembly. While the base trunnion is in the deployed position, the base trunnion is secured to a distal end of the boom assembly and oriented substantially in line with the boom assembly. The jib assembly is secured to the base trunnion and configured to pivot in a substantially vertical plane. The cable strut receives a luffing guy line so as to set an inclined angle of the cable strut relative to the base trunnion.
