摘要： A crane includes a jib posture retention device that retains in a predetermined frontward tilt posture to a boom. The jib posture retention device includes a jib mast that holds a rope connection part at a tensioning position separate from proximal end and a boom distal end backward thereof to render a jib-side support rope and a boom-side support rope linearly tensioned with the jib in the frontward tilt posture. The jib mast is configured to be shiftable to a tension form of holding the rope connection part at a tensioning position in an uprise posture and a looseness allowing form of locating the rope connection part at a looseness allowing position closer to the boom distal end than the tensioning position and closer to the jib proximal end than the tensioning position to allow the jib-side support rope and the boom-side support rope to be loosened.

摘要： A first width direction bending portion (50b) bendably connects a portion of a guy link (50) on a distal end side with respect to a first link portion (50a) to the first link portion (50a) in a width direction. When the guy link (50) is in a stored state, the portion of the guy link (50) located on the distal end side with respect to the first width direction bending portion (50b) is disposed outside the first link portion (50a) in the width direction. When the guy link (50) is in a stored state, at least a portion of the guy link (50) is disposed on the outer side in the width direction than a front strut (32) and on a back surface (21a) or a side surface of a lower jib 21.
