How Traction MRL Elevators Work: A Complete Guide
A Traction MRL (Machine Room-Less) Elevator is a modern elevator system that operates without a separate machine room. It uses a compact motor installed inside the elevator shaft, making it an ideal choice for residential and commercial buildings where space is limited.
How a Traction MRL Elevator Works
1. Electric Motor Drives the System
A gearless or geared traction motor is installed within the elevator shaft.
The motor rotates a drive sheave that moves the elevator.
2. Steel Ropes and Counterweight
Strong steel ropes connect the elevator car to a counterweight.
The counterweight balances the weight of the elevator car, reducing the effort required by the motor.
3. Smooth Vertical Movement
When a passenger selects a floor, the motor turns the sheave.
The ropes move the elevator car up or down while the counterweight moves in the opposite direction.
4. Advanced Control System
A computerized controller manages speed, stopping accuracy, and safety functions.
This ensures a smooth and comfortable ride.
