ABSTRACT:
In a gas turbine that is equipped, on a casing (100) thereof, with a plurality of combustors (1) in the circumferential direction thereof, there is provided a rail (4) which is supported on a rail receiving stand (3) that is movable on the ground and which is disposed in the form of a circular annulus or circular arc in correspondence with the disposition of the combustors (1). A slide mechanism (5, 5a, 6, 6a) is mounted on the rail (4) so as to be movable along the rail (4) and is mounted so that the slide mechanism can enter into and retreat from the interior of the casing (100). A grip mechanism (10) is mounted on an end portion of the slide mechanism and grips constituent parts of the combustor (1), such as a tail pipe (7), a nozzle (9) and an inner cylinder (8). Also, in another aspect of the invention, there are provided a rail (12) that is shaped like a circular arc and is revolvably supported on a revolvable carriage (11), and a grip mechanism (13) that grips constituent parts of the combustor
