METHOD FOR REMOVING GENERATOR ROTOR, METHOD FOR MOUNTING GENERATOR, TURBINE BUILDING, AND GENERATOR FOUNDATION BASE
PROBLEM TO BE SOLVED: To provide a method for removing a generator rotor that reduces a construction period and labor of maintenance of a generator, a method for mounting a generator, a turbine building, and a generator foundation base.SOLUTION: A method for removing a generator rotor includes the steps of: decoupling a generator coupled with a turbine via a revolving shaft of the turbine from the turbine (S11 to S12); supporting the generator with an auxiliary lift machine (S14); saving at least part of a generator foundation base for supporting the generator from a lower floor (S15); dropping the generator from an upper floor where the revolving shaft is disposed to the lower floor by the auxiliary lift machine (S17); and pulling out the generator rotor from the generator that is dropped to the lower floor (S18).SELECTED DRAWING: Figure 8
