The world’s steepest aerial tramway, the Swiss Schilthornbahn project, is not only a tourist attraction but also a serious industrial and engineering challenge. The slope of more than 159%, alpine weather conditions, and strict safety requirements made it clear already in the planning phase that this was a task that could not be solved with standard solutions.
The line transports not only passengers but also provides the logistics material handling required for operation. This called for a custom motion system that operates precisely, safely, and automatically even on extreme gradients, while integrating seamlessly into the overall system.
For similar challenges, BIBUS Kft. applies a solution-oriented, system-based approach, thinking not in individual components but in complete systems.
Previously, material transport was handled by a smaller, partially manual system that could no longer meet the requirements of the new line section. The goal was to develop a linear drive solution that:
This project clearly demonstrates that when standard motion solutions are not suitable for the task, success depends on application-specific system design and targeted engineering support.
During implementation, an electromechanical linear drive system was developed, specifically optimized for the extreme slope of the route. The solution is based on Thomson linear technologies, known in industrial applications for their high load capacity, precise control, and long service life.
The system is built around a high-load Thomson linear actuator, providing precise, controlled motion in both vertical and horizontal directions, even under extreme inclines and environmental loads.
Key technical features of the solution:
This custom linear motion system made it possible for material transport to operate automatically, safely, and efficiently via the transport unit integrated beneath the cabin.
A video was also produced showing the system in operation, clearly illustrating how engineering design becomes a reliable solution in an extreme environment:
▶ Watch the video
The introduction of the new linear drive solution delivered measurable results on multiple levels.
More efficient operation
Replacing helicopter-based material transport significantly reduced operating costs and service times.
Reliable performance in extreme environments
The system operates reliably under high loads and changing weather conditions, with minimal downtime.
Sustainable alpine application
The electrically driven linear motion system contributes to reduced environmental impact and supports long-term sustainable operation.
This project clearly demonstrates that in truly complex applications, the key question is not whether a standard solution is “good enough,” but whether it is fit for the specific task. Success was built on custom system design, system integration, and dedicated engineering support.
