PROBLEM TO BE SOLVED: To provide a boom attaching/detaching device and an attaching/detaching method capable of facilitating attaching/detaching of a boom to/from a revolving superstructure.SOLUTION: A boom attaching/detaching device attaches/detaches a boom which is mounted on a revolving superstructure so as to undulate through a foot pin inserted into a boom bracket of the revolving superstructure and a boom foot of the boom. The boom attaching/detaching device includes: rear support means 31 for supporting a boom base end side on a load-carrying platform rear side of a trailer 27 for transporting the boom (telescopic boom 15); and front support means 32 for supporting a tip side on a load-carrying platform front side. The rear support means includes: a pair of right and left guide rails 33; a jack 34 which is guided by the guide rails and is movably provided; a movable support member 35 which is supported by the jack and is provided to be elevated and to be movable in a longitudinal direction; and a cylinder 36 for moving the jack. The front support means includes: a front side support member 39 provided on the load-carrying platform front side; and a roller 40 provided on the tip side of the boom.SELECTED DRAWING: Figure 1
