To provide a crane capable of adjusting a direction of a load suspended from a hook, and more specifically, provide a crane capable of realizing the improvement in transportation efficiency and preventing the load from colliding with a surrounding building and the like.SOLUTION: A crane includes: a first rotary wire rope 37 suspended from a position which is separated from a sheave 33 in a longitudinal direction of a boom 31; a first pulling device 38 winding/unwinding the first rotary wire rope 37; a second rotary wire rope 39 suspended from a position which is separated from the sheave 33 in a short side direction of the boom 31; and a second pulling device 40 winding/unwinding the second rotary wire rope 39. A load L is rotated to adjust a direction of the load L in such a manner that the first pulling device 38 winds the first rotary wire rope 37 to pull one end of the load L or the second pulling device 40 winds the second rotary wire rope 39 to pull the other end of the load L.SELECTED DRAWING: Figure 3
