To provide a lifting system capable of surely preventing cranes from contacting each other.
A dismantlement system includes: an X direction overhead traveling crane 80 movable in a length direction of an existing building 1 within a horizontal plane of a prescribed height; and a Y direction overhead traveling crane 90 movable in a width direction of the existing building 1 within the horizontal plane of the prescribed height. The X direction overhead traveling crane 80 is provided with a detector 85 for detecting an obstacle with a prescribed range in the horizontal direction around the X direction overhead traveling crane 80 as a detection range B, and when the Y direction overhead traveling crane 90 intrudes inside the detection range of the detector 85, the movement of the X direction overhead traveling crane 80 and the Y direction overhead traveling crane 90 is stopped.
