Aerial lift systems are frequently employed in a mountainous territory where roads are relatively difficult to build and use, and have seen extensive use in mining.
[citation needed] A gondola lift consists of a continuously circulating cable that is strung between two or more stations, over intermediate supporting towers.
[3] Multiple gondola cabins are attached to the cable, usually with detachable grips, enabling them to slow down in the stations to facilitate safe boarding.
[citation needed] A funitel differs from a standard gondola lift through the use of two overhead arms, attached to two parallel haul cables, providing more stability in high winds.
The independent drive also allows for evacuations to occur by means of a bridge connection between adjacent cabins.
[7] The main advantage of the funifor system is its stability in high wind conditions owing to the horizontal distance between the two support ropes.
[6] Chairlifts are continuously circulating systems carrying chairs, which usually enable skiers to board without removing skis.
[10] An example is Ski Arlberg's Weibermahd lift in Vorarlberg (Austria) which alternates between 8-person chairlifts and 10-person gondolas.
[11] In undeveloped areas with rough terrain, simple hand-powered cable-cars may be used for crossing rivers, such as the tuin used in Nepal.
