History

The first cable car system of this type, called ''Alpine Express I'', was built in 1991 in
Saas-Fee Saas-Fee () is the main village in the Saastal, or the Saas Valley, and is a municipality in the district of Visp in the canton of Valais in Switzerland. The village is situated on a high mountain plateau at 1,800 meters (5,900 feet), surrounded ...
. In 1994, a further section, called ''Alpine Express II'', became operational. The cabins of these cable cars have space for 30 people and travel at a speed of 6 m/s pulled by an endless hauling cable, and suspended from two carrying cables. A lane thus consists of three cables, from which the system takes its name. As with most rotating cabin cableways, gondolas are detachable from the cables in order to allow easy disembarkation without disrupting the transit of other cabins on the system. The system offers plenty of advantages, including lower energy consumption, high passenger capacity and comfort, more frequent departures, increased wind stability, larger ground distances and rope spans, and a high driving speed. Development and building of the ''Alpine Express I'' cost 70 million CHF. Von Roll built no more 3S cable cars after the two systems in Saas Fee. When Von Roll was acquired by the Austrian company Doppelmayr in 1996, Doppelmayr obtained the knowledge for 3S gondola lift construction. Doppelmayr constructed their first system in 2002, in

resulted in an unusual span width of 2,507 metres between the valley station and the 80-metre support pillar. Overall, the system cost 13.5 million euros with each cabin costing 100,000 euros. The cableway was manufactured by Doppelmayr. The cable has a diameter of 54 millimetres. The electrical power consumption is 400 kW. There are 19 cabins in total, however the system can be expanded to 24 cabins if the need arises in the future. Each cabin seats 24 people, allowing the system to transport a total of 3,200 people in any given hour. One cabin has a

The Doppelmayr Tri-line

In 2022, Doppelmayr introduced the Tri-line concept, a more compact version of the tricable ropeway that bridges the gap between a monocable gondola and a normal 3s gondola. Compared to monocable gondolas, the Tri-line can be built in more challenging terrain and support longer rope spans. It benefits from proven D-line technology, but with added wind stability up to 110 km/h, less impact on nature and a higher passenger capacity. It features 20-person cabins from CWA called Stella, with place for twelve sitting and 8 standing, as well as the possibility of doors on both sides for better passenger flow. The system can have a passenger capacity of 8000 people per hour and an operating speed up to 7 m/s.
