Monitoring the deformation of cableways

Abstract

One type of aerial cableway consists of a continuous cable, which works at the same time as carrying cable and drawing cable. This kind of cableway is supported by many towers, which divide the total length in linear sections. Even small deviations from the planed layout can increase the strain of the cable and the danger of derailments. The deviations of the position of the towers from the planed layout are due to local sliding or sinking of the foundation or other mechanical movements. Up to now the axis of the cableways were periodically measured by traditional methods.

The goal of this project is to demonstrate the possibility of measuring the axis of a cableway with GPS techniques, while the cable is moving. The results show that the proposed measuring device provides precise results in a simple and reliable way.
