A vehicle is provided for the independent inspection of hard-to-reach inner spaces which are bounded by ferromagnetic inner walls, especially in large cast parts, such as steam chests of a steam turbine. The vehicle includes at least two wheels which are rotatable around a common axis, are at a distance from each other in the axial direction, and can be driven independently of each other. With such a vehicle, the entire inner space can be inspected if the vehicle has adherence elements which hold the vehicle against the gravity force with the wheels on the respective inner wall.
