ABSTRACT:
Wheel assembly capable of maintaining engagement with a rail having an uneven portion therein. The wheel assembly includes a frame adapted to pivot about a pivot axis defined by the frame. At least one wheel is rotatably connected to the frame for traversing the rail. The wheel maintains engagement with the rail as the wheel traverses the uneven portion of the rail because the frame pivots about the pivot axis as the wheel encounters the uneven portion of the rail. Service tooling may be suspended from the wheel assembly to service a nuclear reactor pressure vessel located below the rail.
