Zusammenfassung:A vane arrangement of a turbo machine, in particular of a gas turbine, includes at least one vane carrier attached to a housing of a turbo machine, and several vanes attached to the vane carrier and circumferentially arranged side by side, wherein the attachment between the vane carrier and respective vane is adapted for being axially pluggable. In order to simplify dismounting of a single vane at least one of the vanes is provided with an extraction device having at least one axially extending extraction through-hole. The respective extraction through hole is provided with an inner thread, and the vane carrier is provided with an abutment zone axially opposing the extraction through hole. The extraction device is adapted for inducing axially oriented extraction forces into the respective vane by an extraction tool, which is provided with an outer thread and which is in order to extract the respective vane from the vane carrier inserted into the extraction through-hole and axially pressing against the abutment zone.
