Benefits

This is a space-saving system thanks to the Thanks to the gearless motor and the lack of machine room. The machine is fully speed frequency control guaranteed by contained within the shaft, supported by a high quality inverter, high ride quality, guide rails. The whole lift load is backed by noiselessness within the car and building, the car and counterweight guide rails and better system performance, reduced power neither bearing garden beams to be fixed to the installation and consumption (also in terms shaft home walls nor other masonry works are of energy costs), less mechanical stresses required. The service building cabinet, next to the and motor temperatures are achieved. top landing door, has a reduced depth and minimum aesthetic impact. A range with 630 to 1000 kg load is also available with 2:1 tackle suspension (Overfit-Gearless 21 model): this geometry allows the manufacturing of cars with two opposite entrances.
