General Overhaul of the ENEL Inclined Lift “Campolongo – Colombé”
The general overhaul and technical modernization of the ENEL inclined lift “Campolongo – Colombé”, located between the S. Fiorano power station and the valve chamber near Lake d’Arno (Municipality of Pratovecchio Stia, AR), was successfully completed in full compliance with D.M. 203/2015 and the latest technical sector standards.
Originally built between 1970 and 1971 and previously updated in 1998, the system—measuring 1,825 meters in length with a 1,035-meter vertical drop and a 28-ton capacity—underwent comprehensive refurbishment. The intervention included the replacement of the electric motor, full revamping of electrical panels, and upgrades to control, supervision, and command systems. Key components such as the brakes, gear reducer, drum, and hauling rope were revised, while non-destructive testing was carried out on rollers, pulleys, supports, the vehicle, and the structure. The vehicle itself was overhauled with a focus on the emergency braking system, safety devices, and comfort features for ENEL personnel transport. New event logging, safety systems, and supervision stations were installed, restoring the system to full operational efficiency and ensuring safe, reliable service for internal ENEL operations.
