The LTR 1060 telescopic crawler crane from crane contractor Clausen is used to excursions into the adverse conditions of the Swiss Alps. In autumn 2014 the 60-tonne machine was driven to an altitude of 2,020 metres, overcoming steep inclines and gradients of up to 40 percent. At the time it was used for construction work on a mountain railway tunnel. Liebherr provided support for the crane job with extensive calculations and technical advice.
With this experience behind it, the Clausen team started the planning work for this new job: a crane was needed for the erection work of the mountain station for the new Hirli chairlift in Zermatt. This was being built at an altitude of 2,900 metres. Once again the biggest challenge was gaining access on unmetalled hiking paths.
Clausen transported the crawler crane to Stafelalp at an altitude of 1,900 metres on a compact low loader in mid-September. From there the LTR 1060 had to cover the rest of the distance of eight kilometres on its own. The biggest hurdle that the Liebherr crane had to overcome was a stretch of two kilometres with a gradient of 45 percent. After around five hours the LTR 1060 and the Clausen team finally reached the site at an altitude of 2,900 metres.
