Description
What is a geared traction machine?
The Montanari Giulio PENTA 830 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 PENTA 830 to elevator contractors and distributors worldwide.
