Ceretti built the first aerial cableway with intermediate supports, and was one of the first engineers ever to design and install mechanical systems in harbours and dock yards in order to speed-up the loading and unloading of cargo ships.

long and 1153 metres high, it was the first example with intermediate supports running over rugged ground capable of carrying passengers.

He developed new mechanical methods for moving cargos around, and in 1903 he designed technologies to lift weights, chutes and cableways for the Savona harbour, to load off coal on railway trucks.

His expertise was helpful to the transportation of troops, ammunitions and supplies to the Alpine front line by aerial cable.

Ceretti's expertise and contribution led him to become director of the Technical Department of the Italian Air Force, in Turin.
