Funifor
A Funifor is a type of cable car with two guide ropes, patented by the Doppelmayr Garaventa Group. Two reversible cabins run on parallel tracks and, unlike other types of aerial tramway, the two drives for the two cabins are not interconnected. At the top of each track the haul rope for that track loops back to the bottom instead of looping over to serve the other track. This feature allows for single-cabin operation when traffic warrants. The independent drive also allows for evacuations to occur by means of a bridge connected between the two adjacent cabins. The Funifor system is stable in high wind conditions owing to the horizontal distance between the two guide ropes comprising each track.
