Provided are a crane enabling workability to be improved about connecting a guyline for interconnecting a strut and a boom to the boom, and a crane assembly method. A rope tip part of a winch rope is connected to an intermediate member in a state where a boom and a jib have been fallen on the ground. A winch performs a winding motion of winding the winch rope, thereby raising a strut and making the intermediate member approach a guyline connection part of the boom to allow a boom connection end part of a second guyline that is connected to the intermediate member to be connected to the guyline connection part.

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 includes a boom including a boom distal end part, a jib including a jib proximal end part, a strut 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 wound and delivered by the winch; and a strut support unit attached to the jib back surface or the strut front surface. The strut support unit supports the strut in a fallen posture at a raisable position above the jib in a boom-and-jib fallen state. In the raisable position, a rope connection part to which the rope is connected in the strut is higher than the strut rotation center.
