Claims

[Scope of utility model registration request]

The swivel ring mounting frame is removably fastened to the connecting frame attached to the top of the mast, and is mounted via a swivel mechanism including the swivel ring so that the overhang is located slightly above the bottom surface of the mounting frame. A swivel board that is separated from the base is mounted, and a jib support frame is erected on the upper surface of the overhanging part of the swivel board, and the base end of the jib is pivotally supported on this frame, and the jib is rotated at an appropriate forward position from the pivot part. The rod end of a hydraulic cylinder for luffing, whose base end is pivotally mounted on the board, is connected with a pin, and the jib connects the segments with a two-point pin joint that can be bent and folded laterally at multiple points in the middle. A jib crane with a suspended rope attached to the jib.
