PROBLEM TO BE SOLVED: To solve such a problem associated with conventional methods for periodical inspection on generators in a bus turbine-combined power plant that a gas turbine is dismantled and then a rotor is pulled out before inspection is started, therefore, a schedule for inspection on the entire power plant is prolonged. SOLUTION: A temporary working floor 10 is built above one equipment (steam turbine 120) of a generator 100. Then, the generator 100 is lifted up and its rotor 102 is pulled out to the working floor to inspect the rotor and the stator. For the lift 20, a gantry crane is used. Thus, the rotor and the stator can be inspected in parallel with the overhaul of the gas turbine, and the overall inspection schedule is shortened. COPYRIGHT: (C)2004,JPO
