The document describes two types of bi-cable aerial ropeway systems - continuous and reversible. The continuous system uses two fixed track ropes and a traction rope to haul carriers along the ropes. Carriers are clipped onto the traction rope and run on wheels along the track ropes. The reversible system uses one or two track ropes to haul carriers from the loading station and return them on the same rope. Continuous systems can transport carriers over long distances while reversible systems are shorter and have lower capacities.
