General Overhaul of the “Rigolor – Cima Panarotta” Chairlift
In 2023, the twenty-year general overhaul of the “Rigolor – Cima Panarotta” four-seater chairlift was completed at the Panarotta 2002 ski resort (Municipality of Pergine Valsugana / Frassilongo, TN), in accordance with D.M. 203/2015. Built by Graffer in 2002, the system spans 1,256 meters with a 417-meter vertical drop and a capacity of 1,800 people per hour.
The intervention involved a full inspection and overhaul of all mechanical, electrical, structural, and safety systems. Key components such as the 310 kW main motor, 235 kW recovery motor, braking systems, gear reducer, drive and return sheaves, line rollers, clamps, and hydraulic circuits were serviced or replaced. Non-destructive testing was performed on stations, towers, and vehicles, while the 42 mm Redaelli carrying-hauling rope underwent magneto-inductive testing. The electrical and safety systems were fully revamped with updated panels, signaling devices, and PTS-compliant protections. Structural elements, including concrete foundations and grounding systems, were also tested. Following final checks and documentation updates, the chairlift was returned to full public operation, ensuring safety, efficiency, and operational continuity for the next cycle of service.
