Lifts Bazar on Instagram: "4:1 roping in MRL (Machine Room-Less) elevators is a traction roping system where the elevator car moves 1 unit for every 4 units of rope movement. This setup uses multiple sheaves, creating a mechanical advantage that reduces the required motor force. In this configuration, the motor only supports one-quarter of the total car load, allowing for the use of a smaller and more energy-efficient machine—ideal for MRL systems, which prioritize compact, space-saving designs.
