The hauling cable of the Mottarone cableway broke "due to the degradation of the cable itself which occurred in correspondence with the graft of the cable into the cast head, the most delicate point of the cable". 

The technical experts write this in the document filed yesterday at the registry of the Verbania investigating judge. 

"The cause of the precipitation of cabin no. 3 of the cable car - they add - was the insertion of function exclusions to the emergency braking system required by law and present in cabin no. 3. 

These exclusions prevented, on the occasion of the breaking of the hauling rope, that the emergency braking system was activated, locking the car safely on the supporting rope "." The fractographic analysis - continues the report - has in fact shown that, breaking point of the puller, approximately 68% of the wires have fracture surfaces which testify to a fatigue and fatigue / corrosion failure of the wires reasonably prior to the precipitation of 23 May 2021 ".
