The SK is a people mover built by the company Soulé from Bagnères-de-Bigorre. The acronym SK comes from the initials of the production company (Soulé) and of the designer (Kermadec).
The system is based on small cabins which are circulating on rails and are pulled by a cable at a constant speed. This is directly derived from the gondola lift assemblies which are already produced by the Soulé company and which are working in many ski resorts.
A system of holding mechanism allows to reduce the speed or to halt the cabins in the stations. This technique only works on short lines ; its inability to work on long or curved lines with lots of stops is due to risk of losing the cable and lack of stability at normal speed.
Deployed systems include the following:
