To correspond to the change in the axial length of a rotor.SOLUTION: A rotor hoisting device comprises a beam extending parallel to the axial direction above a rotor body extending in the axial direction, a pair of ring support parts arranged at intervals in the axial direction and detachable from a support ring, rotor support parts arranged at intervals in the axial direction and detachable from the rotor body at different positions in the axial direction from the ring support parts, and supporting the rotor body from below, a vertical position adjustment part that can adjust the position of the rotor support part in a vertical direction Dv relative to the beam, a rotor moving connection part that supports the rotor support part relative to the beam so as to be movable in the axial direction, and a ring moving connection part that supports the ring support part relative to the beam so as to be movable in the axial direction independent of the rotor moving connection part.SELECTED DRAWING: Figure 2

    【課題】ロータの軸方向の長さの変化に対応させる。【解決手段】ロータ吊り具は、軸方向に延びるロータ本体に対して上方で前記軸方向と平行に延びるビームと、前記軸方向に間隔をあけて一対が配置され、支持リングに対して着脱可能とされたリング支持部と、前記軸方向に間隔をあけて一対が配置され、前記リング支持部とは前記軸方向で異なる位置で前記ロータ本体に対して着脱可能とされ、前記ロータ本体を下方からそれぞれ支持するロータ支持部と、前記ビームに対する前記ロータ支持部の鉛直方向Dvにおける位置を調整可能とされている上下位置調整部と、前記ビームに対して前記ロータ支持部を、前記軸方向に移動可能に支持するロータ移動接続部と、前記ビームに対して前記リング支持部を、前記ロータ移動接続部とは独立して、前記軸方向に移動可能に支持するリング移動接続部と、を備える。【選択図】図2
