Provided are a crane capable of improving the workability for lowering and raising a strut, and a method for assembling and disassembling the crane. The crane comprises: a boom (24) including a boom distal end part; a jib (25) including a jib proximal end part; a strut (27) connected to the boom distal end part or the jib proximal end part and raisable and lowerable by vertically rotationally movement about a strut rotation center; a winch; a winch rope (32) wound and delivered by the winch; and a strut support unit (2) attached to the jib back surface or the strut front surface. The strut support unit (2) supports the strut (27) in a fallen posture at a raisable position above the jib (25) in a boom-and-jib fallen state. In the raisable position, a rope connection part to which the rope (32) is connected in the strut (27) is higher than the strut rotation center.
