HOCH-YBRIG, Switzerland – The world’s first Doppelmayr TRI-Line Ropeway is currently being built in Hoch-Ybrig, Switzerland, replacing a 55-year-old reversible aerial tramway. The new TRI-Line system combines a high-performance tricable system with the known advantages of the existing D-Line, allowing for a remarkable 8,000 passengers per hour and direction. The new system provides compact stations and ropeway components, a newly developed trolly, and cabins with room for up to 20 people.
“The TRI-Line uses proven components from the D-Line – for example, the Doppelmayr Direct Drive can also be used effectively in this new system. Another key feature of the TRI-Line is its high wind stability. This is ensured by the two track ropes which form a stable track, a haul rope which moves the cars, and the intermediate suspensions. In addition, round tube supports are used for the TRI-Line. This results in a small footprint and corresponding advantages in the construction phase, such as the airworthiness of the components and short assembly times.“
The TRI-Line also features electric vehicle doors on both sides, allowing for barrier-free entry and improving passenger flow. Plus, as the TRI-Line is a networked ropeway system, it can be fully controlled with the Doppelmayr Connect ropeway control system, and if integrated with the AURO concept, it can run near fully autonomously.
“With the TRI-Line, we have found a ropeway system that meets all our requirements – and at a reasonable price. A single-cable ropeway is feasible from a technical point of view, but would have posed various challenges in the special terrain and would have been correspondingly difficult to build. The 3S lift as an alternative was above our budget. The TRI-Line is compact and, thanks to the 3S advantages, can cope with the prevailing wind in our area, which is a decisive criterion for the important feeder lift. Thanks to the new cabins with their comfortable seats and generous glazing, we can now also offer passengers significantly more comfort.” – Urs Keller, CEO in Hoch-Ybrig
