This equipment uses elevator technology with the cabin rolling on railways. A bundle of ropes hauls the cabins and the movement is provided by a grooved sheave in the driving station. Passengers can access the cabin freely throught by sliding doors. The equipment built between 1977 and 1995 falls under the field of cableways for passenger transport, since no standard was applicable at the time. Since the NF P82-400 standard "Ascenseurs inclines" (Inclined elevators) was published in 1996, the elevators built after the standard are no longer considered as cableways for passenger transport. They are now subject to directive 95/16/CE.
