Overhaul of the ENEL Cable Car “Grumetti–Barbellino”
The complete maintenance and modernization of the ENEL “Barbellino” cable car focused on improving safety, efficiency, and system reliability through a series of targeted upgrades. The intervention included a full overhaul of the main operating system and emergency brakes, as well as the inspection and modernization of hydraulic units and high-altitude piping to extend their service life.
The gearbox, along with both the recovery and emergency winches, underwent detailed inspections and complete overhauls, including their hydraulic systems and piping. A thorough revision of the vehicle, suspension trolley, and cabin was carried out to restore structural integrity and passenger comfort, while the trolley brake hydraulic unit was upgraded for improved response. The electrical control systems and wiring were also brought up to current safety standards. Additional work included maintenance and refinishing at the lower station and on the line towers, with cladding replacement on the third tower. Line and emergency rollers were inspected, refurbished, and fitted with new rings where necessary, and precise adjustments were made to ensure proper movement and alignment of the carrying cables, reducing wear and extending system life. A spare parts inventory was also replenished to support long-term maintenance. The final phase included commissioning, internal testing, and safety certification, confirming full regulatory compliance and delivering a safe, high-performance installation ready for continued operation.
