Abstract
A rope routing step and a raising step are executed. In the rope routing step, in a state where a raisable and lowerable member and a boom are laid down, a raising rope is coupled to the raisable and lowerable member and routed to extend rearward of the raisable and lowerable member. In the raising step, the raising rope is wound up rearward to raise the raisable and lowerable member. In the rope routing step, the raising rope is routed to pass between a lower restriction section and an upper restriction section of a rope support member, and in the raising step, the raising rope is wound up rearward with a vertical movement of the raising rope restricted by the upper restriction section and the lower restriction section.
