Funifor

A funifor is a type of aerial lift or aerial tramway patented by Doppelmayr Garaventa Group which consists of two guide ropes and a haul rope loop per cabin. The drives of the two cabins are not interconnected with two reversible cabins running on parallel tracks. 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 as occurs with a normal aerial tramway. In other words, a funifor's propulsion is not returned to the opposite direction for use by the other vehicle.
