• TRI-Line

With the new Weglosen–Seebli ropeway, a world premiere launched in Hoch-Ybrig (Switzerland) at the end of 2025: the first installation featuring the innovative TRILine ropeway system. Cutting-edge technology, a newly developed carriage, a barrier-free cabin, and the capacity for autonomous operation are its standout features.

TRI-Line is a new ropeway system developed by Doppelmayr Group (projekt leader Garaventa) and represents an evolution of tricable technology. It combines the advantages of highperformance 3S technology with those of the proven D-Line generation, impressing with compact stations and towers.

Designed for Autonomous Operation

The new TRI-Line in Hoch-Ybrig is AURO-capable. AURO stands for Autonomous Ropeway Operation and enables operation without on-site personnel. Depending on requirements, the system can be run in two modes: In conventional operation, staff monitor the valley and mountain stations, allowing for full transport capacity – ideal for peak traffic in the ski resort.

In AURO mode, boarding and disembarking take place through gates while the cabin is stationary. Operation is video-monitored and centrally controlled via the Ropeway Operation Center (ROC) in the mountain station. The system automatically detects deviations, slowing down or stopping operation if necessary:

In such cases, personnel manually resume operation at the mountain station once the cause has been resolved. The operator can switch flexibly between modes to optimize resource deployment.

The TRI-Line Carriage

The heart of the TRI-Line is its newly developed carriage: Two D5000 grips grasp the rope from above, while eight rollers – four on each track rope – guarantee smooth travel and stability, even in high winds. The ropeway utilizes numerous proven components from the D-Line and 3S systems, simplifying maintenance and operation for the ropeway team.

The TRI-Line Cabin

CWA developed a completely new cabin, the STELLA, which was finished in vibrant red at the customer‘s request. The cabins offer space for 18 people (12 seated and 6 standing) and feature a TWISTIN ski rack, where skis can be placed directly into the cabin floor. Panoramic windows offer unobstructed views, while level-ground boarding ensures barrier-free access.

• AURO CLD

With AURO MGD, the autonomous operating concept for monocable gondola lifts, the Doppelmayr Group set a milestone in the industry as early as 2020. Only three years after the autonomous solution for gondolas, AURO CLD made it possible for the first time to operate the mountain stations of chairlifts autonomously using Artificial Intelligence.

Since then, the technology has enjoyed a true streak of success: more and more operators are choosing AURO CLD, most recently the Austrian ski resorts of Sölden and Ischgl for the 8-seater chairlifts Einzeiger, Silberbrünnl, Höllboden, and Sassgalun.

• AURO ASSIST

While AURO CLD enables autonomous operation of the exit area, AURO Assist focuses on the boarding area. The view of the exit in the valley station is often restricted for the operating team, and safety bars do not always provide complete protection against accidents in these situations. However, to consistently improve passenger safety, a fast and reliable assessment of the passenger‘s seating position during and after boarding is essential.

The task of AURO Assist is therefore not to replace operating personnel during boarding, but to support them regarding visibility and thus increase passenger safety.

How does AURO Assist work?

For the necessary AI-supported image recognition, the Doppelmayr Group relies on the expertise of its technology partner Mantis Ropeway Technologies, as it does with AURO CLD. Usually, two or three cameras provide the video feed, which the system uses to detect if a passenger has taken an incorrect seating position.

In such a case, AURO Assist stops the installation immediately. Every tenth of a second can be decisive; therefore, integration into the ropeway control system is necessary and enables an immediate reaction. Due to the inertia of a ropeway system, it is impossible to bring the installation to a standstill without delay.

The goal must therefore be to stop the system before the passenger reaches a potentially critical fall height. Based on the stabilization zone according to EN12929-1, this has been defined as three meters. AURO Assist prevents this limit from being exceeded if the worst comes to the worst.

Individual conditions

Conversely, this means that not every installation is automatically suitable for AURO Assist due to topography – for example, if the terrain drops steeply immediately after the station or if a river is crossed at that same point. However, there are solutions even in these cases.

In any case, the field of application is broad and market interest is high: a total of eight chairlifts already rely on AURO Assist support. The system is suitable for new detachable chairlifts from manufacturers Doppelmayr and Garaventa, with or without bubbles, as well as existing installations with PSS3000 control systems or higher.
