A device for installing and removing a component, preferably a burner or a transition pipe of a gas turbine, on or in a stationary gas turbine, is provided. The device includes a rail system having a frame carriage that can be moved along the rail system, on which frame carriage an insertion unit having a carrier unit for the component that can be moved along a movement axis is arranged. In order to specify an especially space-saving and especially rigid design, by means of which components of a gas turbine can be installed and removed relatively simply and quickly, the rail system is designed as a two-track rail system and the movement axis extends between the two rails transversely to an area that extends between the rails.
