The invention provides a large and medium-sized horizontal hydro-generator stator overturning and hoisting device and method, and the device comprises at least two overturning supports which are fixed on the ground and are respectively hinged to the lower side of the right end of a stator; the at least two turning-over ground anchors are fixed on the ground, and the distance between the turning-over ground anchors and the right end face of the stator is larger than the diameter of the stator; the first connecting point is positioned on the upper side of the right end of the stator and is correspondingly matched with the turnover ground anchor; the first tension device is connected with the first connecting point and the corresponding turnover ground anchor so as to be used for pulling the stator to rotate along the turnover support; the second connecting point is located at the upper end of the stator, and the second tension device is connected with the second connecting point and the external hoisting device so that the external hoisting device and the stator can be in the stress state all the time. The stator overturning device has the advantages of being stable and safe in overturning process, high in overturning efficiency and not prone to damage stator components.
