The Montaz-Mautino company was founded 40 years earlier by Pierre Montaz and Victor Mautino in the commune of Fontaine, Isère.

After these turbulent times, the manufacturer refocused on making chairlifts and ski lifts, its historic know-how, and after the sales service of the previous-Montaz Mautino and Gimar installation.

GMM mainly builds four-seater fixed-attachment chairlifts and roller or pole-mounted ski-lifts and provides after-sales service on old products designed by the two former companies Montaz-Mautino and Gimar.

The current range of GMM chairlifts is based on 7+ stations and mini 7 of motor type or motor-voltage compacts (on massive concrete).

GMM has developed for this purpose a so-called range E (as winders) with 3 different driving-voltage terminals; the lighter is sized to fit devices for beginners, the heart of the product target.
