An aerial tramway, or cable car, is a type of aerial lift which uses one or two stationary ropes for support while a third moving rope provides propulsion. With this form of lift, the grip of an aerial tramway cabin is fixed onto the propulsion rope and cannot be decoupled from it during operations.
The first aerial tram was built in 1644 by Adam Wiebe, a Dutch engineer and inventor born in Harlingen. It was used to move soil to build defences. Other mining systems were developed in the 1860s by Hodgson, and Andrew Smith Hallidie. Hallidie went on to perfect a line of mining and people tramways after 1867 in California and Nevada.
