Jib feet are provided on both the left and right sides of the base end, and one of these jib feet on both sides is configured as a movable jib foot that can rotate around its axis. When in use, both jib feet are attached to a boom point that protrudes from both left and right sides of the boom tip. The movable jib foot is extended from the tip of the boom while engaging the pin, and is stored on the side of the boom when not in use. In the auxiliary jib of a wheel crane that is suspended from the tip of the boom so that it can twist and rotate around the axis of the jib foot, there is a
A wheel characterized in that a handle located on a straight line passing through the movable jib foot and the center of gravity of the auxiliary jib, and a rotation operation arm to which a twist rotation operation force is applied with the handle as a central axis are provided substantially perpendicular to each other. Auxiliary jib for type crane.
