摘要：<p>Disclosed is an invention relating to a method of withdrawing a rotor shaft of a generator in a combined power generation plant using a lifting apparatus. The disclosed method of withdrawing a rotor shaft of a generator in a combined power generation plant using a lifting apparatus, wherein a gas turbine including an upper casing assembly and a lower casing assembly, a generator and a steam turbine are arranged in the combined power generation plant, comprising the steps of: separating the upper casing assembly from the lower casing assembly, thereby forming a movable space part in the gas turbine; separating the rotor shaft of the generator that is flange coupled to a shaft of the gas turbine and to a shaft of the steam turbine; installing a lifting apparatus in the generator and lifting the generator using the lifting apparatus; hanging the lifting apparatus from an end portion of the rotor shaft exposed in the direction of the gas turbine in the generator by using a lifting member connected to an overhead crane; moving the overhead crane and pulling the rotor shaft in the direction of the movable space part by means of the lifting member, thereby withdrawing a portion of the rotor shaft; and hanging a central portion of the rotor shaft from the lifting member and withdrawing, lifting and moving the entire rotor shaft.</p>
