Abstract:
A crane having a boom and a jib swingable on the boom between a taken in position and a stretched out position includes a jib holding construction. A jib hold rod is movably mounted on the jib between a first position in which a base end of the jib hold rod is connected to the jib when the jib is in the taken in position, and a second position in which the base end of the jib hold rod is connected to a portion of the boom for supporting the jib in the stretched out position. A rod holding link is mounted to the jib for selectively holding the base end of the jib hold rod at a correct position for connection to the boom when the jib is swung out to the stretched out position. This avoids the need to manually locate the jib hold rod in the second position when the jib is stretched out.
