ンのジブ張出し、格納装置。 The jib is equipped with a telescoping boom and a compression column type jib that extends from the tip of the boom. Jib mounting shafts are provided on both the left and right sides of the jib, while jib feet that can be attached to and detached from the jib mounting shafts are provided at the base ends of the main girders on both sides of the jib. The jib foot located on the lower side can freely rotate around an axis that is shifted downward from the main girder when the jib is stored, and can rotate on the same axis as the main girder. The jib foot is mounted so as to be slidable toward and away from the base end of the main spar, and includes means for removably connecting the jib foot and the base end of the main spar in a close state. Crane jib extension and storage equipment.
