Ropeways Monitoring Zermatt

Permanent ropeways pillar monitoring

Project: 2018 - ..., Zermatt, Switzerland
Client: Zermatt Bergbahnen AG

Thawing permafrost due to global warming or other changes in the subsoil can lead to instability in mountain railways and restaurants. Zermatt Bergbahnen decided to monitor this problem with permanent GNSS and laser distance measurements on various mountain railway masts. Depending on the task, the GNSS sensors were attached to the mast foundations or the yoke. The laser distance sensors permanently measure distances between large support feet in order to detect uneven deformations.

In this way, the mountain railways increase the safety of their installations and can immediately initiate appropriate stabilisation measures in the event of any movements in the terrain or foundations. Knowing the exact, daily updated 3D position of the masts also allows the maintenance of the lifts to be optimised, which can lead to cost savings.
