The turbo-alternator case is positioned into rings and laid on rotator mod. R60C, special execution, weight capacity 600 ton/pair, steel wheels superficially hardened, Ø 1200 x 600mm width, tangent force delivered by motorized section 26 ton.

The wrong positioning of the case inside the rings, sometimes causes an axial drift of such an extent and drifting speed that can not be effectively opposed by the anti-drift automatic system installed on the idle section. Therefore, both drive and idle sections have been equipped with electronic probes that, when detecting the approach of rings to pre-set safety limits, automatically stop any activity.
Rotation can only be reactivated after a safety procedure and by means of a key switch.
