A crane was needed for the erection work of the mountain station for the new Hirli chairlift at an altitude of 2,900 metres in Zermatt. The biggest challenge for the LTR 1060: gaining access on unmetalled hiking paths.

Crane operator 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.

After the crawler crane had shown its outstanding off-road capabilities, it then demonstrated its crane performance over the next few days. First of all it installed the steel structure for the new mountain station. It then had to assemble the drive engine. To do this the LTR 1060 first had to be driven to the assembly site carrying the 16-tonne engine before it could hoist it into position. This so-called "pick-and-carry" operation is a major selling point for telescopic crawler cranes. They can travel holding a full load which makes them particularly flexible to use. After completing the job and spending around three weeks at this altitude, the 60-tonne machine then had to tackle the downhill journey.
