A 360° view of the 8th wonder of the world, in complete safety

Ascending in the heart of the massif of Monte Bianco is an experience that has been dubbed the eighth wonder of the world, attracts more than 100,000 visitors per year, and this is set to increase. The new Monte Bianco installations, erected by the Cordee Mont Blanc Consortium, using the Doppelmayr Italia cableway technique, go as far as Punta Helbronner in the form of two sections of a new line that replaces the three old cableways. 

The uniqueness of this project lies in the multiple technical innovations, the challenges that had to be overcome during construction, and its particular architecture.  These include the modern glass and steel stations, the concept of sustainability aimed at achieving energy autonomy, and the transporting capacity, to which the experience of travellers must be added.  Some of the technological highlights of this project include the highest cableway support in the world that, not countering the foundation anchoring system, soars up to a height of 110 metres.

The worksites were located at altitudes of 1,300, 2,220 and 3,500 metres, with an overall difference in altitude of 2,200 metres and a total length of the two sections of 4,3 km.

Redaelli was involved in constructing the system in collaboration with the Doppelmayr / Garaventa Group, which leads the way in cableway engineering - in fact, it provides the steel cable system specifically designed for this cableway.  Eight reels of loadbearing cable, four reels of traction cable, and two reels of rescue cables.
