CRANE AND METHOD FOR ASSEMBLING AND DISASSEMBLING CRANE

原文（中文）

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.
