Monocable detachable gondolamonocable detachable gondola (MDG) is a common type of aerial lift, with a single steel cable strung between two or more stations, supported by intermediate towers. Many gondola cabins hang from the cable via a detachable grip, which allows the cabins to detach from the cable and slow down at each station. The cable provides both support and propulsion for the gondolas.
Examples of monocable detachable gondolas
3S gondola lift
A 3S gondola lift or tricable detachable gondola (TDG) is a gondola technology that uses three steel wire ropes (drei Seile in German, giving the name "3S"). Two of the ropes support the weight of the gondola cabins, while the third rope provides propulsion.

An aerial tramway is a type of aerial lift with one or two cabins fixed to a cable. The distinguishing feature of aerial tramways is that the cabins shuttle back and forth between the end stations of the lift in a reversible manner. Aerial tramways are usually built with three steel wire ropes - two for support and one for propulsion. (This is the same rope configuration used by 3S gondola lifts, but 3S lifts operate with continuous circulation and have detachable cabins).
