A machine-room-less (MRL) elevator operates without a dedicated machine room by integrating the machinery and other necessary components within the elevator shaft or adjacent spaces. Here's how it functions:

1. Hoisting System: In traditional elevators, a machine room houses the motor and pulley system used to move the elevator car. In an MRL elevator, the hoisting machinery is typically located on top of the elevator shaft or within the shaft itself. This system usually consists of a compact gearless traction machine, ropes or belts, and a counterweight.

2. Control System: The control panels and equipment, which are usually situated in the machine room, are incorporated into the elevator shaft or a nearby cabinet. These control systems manage the elevator's operation, including the movement, floor selection, and safety features. The controls communicate with sensors, buttons, and indicators in the elevator car and the floors.

3. Space Optimization: MRL elevators are designed to maximize space efficiency, utilizing the available shaft dimensions effectively. By eliminating the need for a separate machine room, MRL elevators can be installed in buildings with limited space yet still provide adequate functionality.

4. Compact Design: MRL elevators are engineered to have compact machine and control systems, allowing them to fit within the confined space of the shaft. The elevator components are designed to be lighter and smaller compared to those used in traditional systems, yet they maintain sufficient power and capacity to move the elevator car smoothly.

The concept of a machine-room-less elevator revolves around integrating the essential machinery and control systems within the elevator shaft or adjacent areas, eliminating the need for a dedicated machine room while ensuring safe and efficient operation.
