Eker SMART 4 Geared Elevator Traction Machine
Eker SMART 4 is a 4 kW geared elevator traction machine for machine-room lift projects, designed for reliable torque transmission, smooth travel and durable operation.
Description
What is a geared traction machine?
The Eker SMART 4 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 Eker SMART 4 to elevator contractors and distributors worldwide.
