A vertically oriented redundancy pipe (6) is arranged in an area of the vertical bar, where an opening (17) is attached at an end of the redundancy pipe in a vertical direction. The opening is partially closed according to a malfunction of a vertical bearing attached to the pipe under loading a vehicle such that misalignment of the plate is determined and registered.
