Rotor hanging tool, rotor support jig, rotor lifting method, and rotary machine disassembly method

A rotor hanging tool for hanging a rotor provided with a rotor main body extending in an axial direction, a pair of annular support rings respectively disposed at a first end and a second end of the rotor main body at an interval in the axial direction and provided outside the rotor main body in a radial direction, and a pair of seal members disposed on an inner peripheral surface of the support ring in a state where a space is open between the seal member and an outer peripheral surface of the rotor main body, the rotor hanging tool comprising:

• a beam extending in parallel to the axial direction above the rotor main body;
• a pair of ring support portions disposed at an interval in the axial direction, connected to the beam, and attachable to and detachable from the support ring;
• a pair of rotor support portions disposed at an interval in the axial direction, connected to the beam, attachable to and detachable from the rotor main body at positions different from the ring support portions in the axial direction, and respectively supporting the rotor main body from below;
• and
• a vertical position adjustment unit configured to adjust a position of each of the rotor support portions in a vertical direction with respect to the beam.
