SWR Documentary: Fall-proof rope testing at the Predigtstuhlbahn

SWR documentary: Fall-proof – with ROPESYS rope testing systems in use worldwide.

The 30-minute SWR documentary “Seilbahnchecker” focuses on rope inspections – carried out using the high-tech system from ROPESYS. The camera follows our experts as they inspect two cable cars: the historic Predigtstuhlbahn in Bad Reichenhall and the 3S-Bahn in Koblenz.

Rope safety since 1928 – technically rethought

The Predigtstuhl cable car is a true piece of technical history—but it still has to be safe. This is where ROPESYS comes in: Our testing systems enable detailed cable inspections, including state-of-the-art magnetic induction measurement technology.

Comprehensive rope inspection with ROPESYS

For many years, the historic railway has been inspected by independent experts – including our partner company ROTEC. This involves more than just the suspension cable: the control system, mechanics, statics, and fire protection are also inspected. Because only a technically sound condition ensures the operating license.

Magnetic inductive rope testing in action

Visual inspection isn’t enough. Therefore, we also conduct a magnetic inspection of the rope’s interior using our ROPESYS device. This creates a precise magnetic field around the rope, revealing any weak spots. Deviations from the target condition can be measured live as a stray field – contactless, in 3D, and wirelessly.

Real-time data analysis via the ROPESYS Cloud

The initial evaluation takes place directly on-site: A laptop receives live data during the journey. An AI-supported analysis then performs the complete evaluation – securely and efficiently via the ROPESYS Cloud. This allows weak points to be identified early and downtime to be avoided.

Cable car safety thought globally

Whether in Germany or worldwide – ROPESYS ensures safe cable car operations with state-of-the-art systems. Our solutions are also in use in Bolivia: In the city of La Paz, with a population of one million, they support the maintenance of one of the world’s largest urban cable car networks.

The SWR documentary shows how modern technology protects lives.

A look behind the scenes of our work and a clear statement: rope testing is high-tech. Anyone interested in the safety behind the scenes shouldn’t miss this report.
