Montanari M83-M85 RANGE Elevator Traction Machine
Montanari M83-M85 RANGE is an Italian geared elevator traction machine designed for reliable lift applications in 10-passenger elevators, trolley lifts and heavy goods lifting.
Description
What is a geared traction machine?
The Montanari Giulio M83-M85 RANGE is a geared elevator traction machine. A geared machine drives the sheave through a worm or helical gearbox, which multiplies torque and allows a smaller, lower-cost motor to move the same load.
Geared machines are typically specified for machine room (MR) elevator systems at low to medium speeds, and for freight and goods lifts where high starting torque matters more than energy efficiency. Nazar Elevator supplies the Montanari Giulio M83-M85 RANGE to elevator contractors and distributors worldwide.
