Eker STRONG 7.5 Geared Elevator Traction Machine

Eker STRONG 7.5 is a professional geared elevator traction machine developed for machine-room elevator installations where robust mechanical performance, serviceability and long-term reliability are required. The STRONG Series configuration is suitable for passenger, service and medium-to-heavy duty lift projects depending on the final capacity, speed, suspension and sheave selection. Its geared drive architecture supports controlled torque transmission, stable ride quality and practical maintenance access. For Nazar Elevator projects, this model can be specified as part of complete elevator packages, modernization works or component supply programs. Final selection must always be confirmed according to shaft conditions, rated load, car speed, roping ratio, brake requirements and the official Eker technical data sheet.

What is a geared traction machine?

The Eker STRONG 7.5 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 STRONG 7.5 to elevator contractors and distributors worldwide.
