Abstract

See full text

Provided is a crane which comprises a luffing jib including a lower jib and an upper jib coupled to the lower jib in such a manner as to be separable from the lower jib, the lower jib is attached to a head of a boom to have a laid-down posture at a position between the boom and a strut when the upper jib is separated from the lower jib, when the boom is lowered and laid down to allow the head of the boom to come into contact with a ground and when the strut is lowered and laid down to allow a distal end of the strut to come into contact with the ground, and the lower jib has a length which causes no interference with the strut when the lower jib has the laid-down posture at the position between the boom and the strut.
