A Fassi crane Multi-Tasking on Mont Blanc - continued
As the works progressed, the Fassi F425RA crane delivered a number of other operational benefits. For example, when wind speeds reached 70 km/h - not a rare occurrence, as they can sometimes top 150 km/h at this height - the tower cranes had to stop working for safety reasons. The Fassi crane, however, was able to continue.
Work started in April 2011 and by the following year the F425RA e-dynamic crane was already operational. It was first installed at the lift shaft that connects the Punta Helbronner arrival station with the tunnel down to the Nuovo Rifugio Torino, a refuge building located 100 metres below.
An advantage of the articulating crane was the speed with which it could be moved around the site to where it was needed next.
The Fassi crane was then installed at the top of the structure where, using its winch, it was a used in placing reinforcing steel during cement casting. The next step was the construction of the two-storey station structure, always moving on to the floor above as each concrete pour neared completion. Its contribution was also crucial in laying of the steel girders and crossbeams.
During the winter breaks the crane remained outdoors, covered only by a tarpaulin in temperatures that reached minus 30° C. When work resumed, the crane was ready, as was the case every morning, even after the worst storms.
For the final stages, the Fassi F425RA crane was fitted with the work platform basket allowing contractors to gain the height for tightening the bolts and installation of doors, windows and the solar panels.
