General Overhaul of the REGIONAL Cable Car “Buisson–Chamois”
In 2021, the general overhaul of the bi-cable “Buisson–Chamois” cable car (KB14), located in the Aosta Valley and operated by the Autonomous Region, was successfully completed to ensure compliance with D.M. 203/2015 and EU Regulation 2016/424.
Connecting Buisson (1120 m) to Chamois (1812 m), the system underwent a full twenty-year maintenance program that included non-destructive testing on major structures, a complete overhaul of pulleys, brakes, winches, trolleys, and suspensions, as well as replacement of the ballast rope and carriage ropeheads, rope movement, and carriage renewal. The electrical, pneumatic, and hydraulic systems were updated, including motors, gear reducers, generators, and the braking system. Both cabins were structurally and functionally upgraded, with new glass panels, opening mechanisms, accessibility features, and internal systems. A modern control and supervision system was installed, featuring CE-certified panels, redundant safety PLCs, remote control, in-line video surveillance, and two-way communication. Additional interventions included line support restoration, lifting hoist replacement, buffer modernization, and regulatory adaptation for unattended operation. The project concluded with final testing and technical documentation updates, ensuring continued safe, reliable public service with a technologically upgraded system.
