An aerial lift,{{Cite web|url=http://www.skilifts.org/old/glossary.htm|title=Skilifts.org - Glossary of Aerial Lift Terms|website=Skilifts.org|access-date=26 June 2022}} also known as a cable car or ropeway, is a means of cable transport in which cabins, cars, gondolas, or open chairs are hauled above the ground by means of one or more cables. 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. Aerial lift systems are relatively easy to move and have been used to cross rivers and ravines. In more recent times, the cost-effectiveness and flexibility of aerial lifts have seen an increase of gondola lift being integrated into urban public transport systems.{{Citation needed|date=December 2020}}

An aerial tramway, aerial tram (American English) or a cable car (British English), uses one or two stationary ropes for support while a separate moving rope provides propulsion.[http://gondolaproject.com/2010/04/24/technologies-module-5-aerial-trams/ The Gondola Project] {{Webarchive|url=https://web.archive.org/web/20170517212252/http://gondolaproject.com/2010/04/24/technologies-module-5-aerial-trams/ |date=2017-05-17 }} Aerial Technologies, Lesson 5: Aerial Trams - Retrieved on 2010-04-24 The grip of an aerial tramway is permanently fixed onto the propulsion rope. Aerial trams used for urban transport include the Roosevelt Island Tramway in New York City, as well as the Portland Aerial Tram.{{Citation needed|date=December 2020}}

A gondola lift consists of a continuously circulating cable that is strung between two or more stations, over intermediate supporting towers. The cable is driven by a bullwheel in a terminal, which is connected to an engine or electric motor.[http://adr.coalliance.org/cog/fez/eserv/cog:165/neumann.pdf Cable Propelled Systems in Urban Environments] {{Webarchive|url=https://web.archive.org/web/20120314141047/http://adr.coalliance.org/cog/fez/eserv/cog%3A165/neumann.pdf |date=2012-03-14 }} Edward S. Neumann - Retrieved on 2010-08-05 Multiple gondola cabins are attached to the cable, usually with detachable grips, enabling them to slow down in the stations to facilitate safe boarding. Fixed-grip variants exist, although these are considerably less common. Lifts with a single cable are sometimes referred to as "mono-cable" gondola lifts. Depending on the design of the individual lift, the capacity, cost, and functionality of a gondola lift will differ dramatically. Because of the proliferation of such systems in the Alpine regions of Europe, the French language name of télécabine is also used in an English-language context. Gondola lifts are also used for urban transportation. Examples include the Singapore Cable Car, Metrocable (Medellín), Metrocable (Caracas), Mi Teleférico (La Paz), and London Cable Car.{{Citation needed|date=December 2020}}

Gondola lifts which feature one stationary 'support' rope and one haul rope are known as bi-cable gondola lifts, while lifts that feature two support ropes and one haul rope are known as tri-cable gondola lifts. Examples include Ngong Ping Skyrail (Hong Kong) and the Peak 2 Peak Gondola (Canada).{{Citation needed|date=December 2020}}

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.{{Cite web|url=http://gondolaproject.com/funitel/|title=funitel « The Gondola Project|website=Gondolaproject.com|date=28 October 2011|language=en-US|access-date=2019-04-22}} The name funitel is a blend of the French words funiculaire and telepherique. Systems may sometimes be referred to as "double monocable" (DMC), where two separate haul cables are used, or "double loop monocable" (DLM) where a single haul cable is looped round twice.{{Citation needed|date=December 2020}}
Funitels combine a short time between successive cabins with a high capacity (20 to 30 people){{Cite web|url=http://www.seilbahntechnik.net/lifte/Ort/funitel/page1.php|archiveurl=https://web.archive.org/web/20120210134151/http://www.seilbahntechnik.net/lifte/Ort/funitel/page1.php|url-status=dead|title=Lift-World :: Lift-Database - Funitels|archive-date=10 February 2012|access-date=26 June 2022}} per cabin.

A funifor is a type of cable car with two support ropes and a haul rope, looped around. Each system is composed of a single cabin shuttling back-and-forth. Many installations are built with two parallel, but independent, lines. The funifor design was developed by the Italian manufacturer, Hölzl, which later merged with Doppelmayr Italia. Today, the design is therefore patented by Doppelmayr Garaventa Group.{{cite web |title= Funifor |publisher=Doppelmayr Garaventa Group |url=http://www.doppelmayr.com/nc/en/doppelmayr-international/products/funifor.html?country=all&sword_list%5B%5D=funifor |access-date= 2010-12-10}}
At the top of each track, the haul rope loops back to the bottom instead of looping over to serve the other track, as would occur with a normal aerial tramway. This is shown in the diagram below. This feature allows for a single cabin operation when traffic warrants. The independent drive also allows for evacuations to occur by means of a bridge connection between adjacent cabins.

The main advantage of the funifor system is its stability in high wind conditions owing to the horizontal distance between the two support ropes.

Chairlifts are continuously circulating systems carrying chairs, which usually enable skiers to board without removing skis. They are a common type of lift at most ski areas and in mountainous areas. They can also be found at some amusement parks and tourist attractions.{{Cite web|url=https://liftblog.com/scenic-skyway-knoebels-pa/|title=Scenic Skyway - Knoebels, PA}}
Detachable chairlifts usually move far faster than fixed-grip chairlifts, typically {{convert|5|m/s|ft/s|1|abbr=on}} compared with {{convert|2|to|2.5|m/s|ft/s|abbr=on}}. Because the cable moves faster than most passengers could safely disembark and load, each chair is connected to the cable by a powerful spring-loaded cable grip which detaches at terminals, allowing the chair to slow considerably for convenient loading and unloading at a typical speed of {{cvt|0.75|m/s|ft/s}}, a speed slower even than fixed-grip. Chairs may be fitted with a "bubble" canopy to offer weather protection.{{Citation needed|date=December 2020}}

A hybrid lift is a fusion of a gondola lift and a chair lift. The company Leitner refers to it as telemix,{{Cite web|url=https://www.leitner-ropeways.com/en/products/telemix-24/|title=Telemix - Products - LEITNER ropeways|website=Leitner-ropeways.com|language=de|access-date=2019-08-14}} while Doppelmayr uses the term combination lift.{{Cite web|url=https://www.doppelmayr.com/en/products/combination-lift/|title=Combination Lift {{!}} Products|website=Doppelmayr.com|access-date=2019-08-14}} An example is Ski Arlberg's Weibermahd lift in Vorarlberg (Austria) which alternates between 8-person chairlifts and 10-person gondolas.{{Cite web|url=https://www.doppelmayr.com/en/products/references/810-cgd-weibermahd/|title=8/10-CGD Weibermahd|website=Doppelmayr.com}}

Material ropeways

{{Main|Material ropeway}}
A material ropeway or ropeway conveyorErnst, Dr.-Ing. Richard (1989). Wörterbuch der Industriellen Technik (5th ed.). Wiesbaden: Oscar Brandstetter, 1989, p. 659. {{ISBN|3-87097-145-2}}. is an aerial lift from which containers for goods rather than passenger cars are suspended. These are usually monocable or bicable gondola lifts.
Material ropeways are typically found around large mining concerns, and can be of considerable length. The COMILOG Cableway, which ran from Moanda in Gabon to Mbinda in the Republic of the Congo, was over 75 km in length. The Norsjö aerial tramway in Sweden had a length of 96 kilometers.{{Citation needed|date=December 2020}}
