Industry knowledge about this item

Machine Room Less (MRL) elevators are a type of elevator system that does not require a traditional machine room to house the elevator's machinery. Instead, the machinery is located within the hoistway or in a compact machine room located adjacent to the hoistway.
MRL elevators use compact and efficient machinery, such as gearless traction machines and permanent magnet synchronous motors, which are designed to fit within the hoistway or in a small machine room. This reduces the overall size of the elevator system, making it possible to install an elevator in a smaller footprint.
In addition to saving space, MRL elevators are also more energy-efficient than traditional elevators, as they do not require a separate machine room with their own ventilation, lighting, and cooling systems. This can result in lower energy costs and a more environmentally friendly building.

Advantages of Machine Room Less (MRL) elevators:

Space savings: MRL elevators do not require a separate machine room for the hoisting machinery and control equipment, which allows for more efficient use of space in buildings.
Cost savings: The absence of a separate machine room reduces the cost of installation and maintenance compared to traditional machine room elevators.
Improved aesthetics: MRL elevators have a more streamlined appearance as the machinery and control equipment is located within the elevator shaft or in a compact machine room located adjacent to the shaft.
Increased reliability: MRL elevators have fewer components and are less complex than traditional machine room elevators, which can result in increased reliability and reduced maintenance costs.
Improved safety: MRL elevators typically have advanced safety features, such as redundant safety brakes and emergency power systems, to ensure the safety of passengers in the event of a power failure.
Increased energy efficiency: MRL elevators typically use more efficient and compact motors and control equipment, which can result in reduced energy consumption and lower operating costs.


A machine room less (MRL) elevator works by housing the elevator's machinery and control system within the hoistway, the shaft in which the elevator car travels. This allows for a more compact and efficient design, as the machinery is located directly above or below the elevator car.

Here's a general overview of how an MRL elevator works:

The elevator car is attached to a hoisting rope or cable that is wound around a motorized pulley.
The motor and control system are located within the hoistway, near the top or bottom of the shaft.
When a call is placed for the elevator, the control system directs the motor to move the hoisting rope or cable, either up or down, to bring the elevator car to the desired floor.
The control system also monitors the position of the elevator car and adjusts the speed of the motor to ensure smooth and safe operation.
When the elevator car reaches the desired floor, the control system activates the door-opening mechanism, and the doors open.
Once the passengers have entered or exited the elevator car, the doors close and the control system directs the motor to move the hoisting rope or cable to the next floor.
The compact design of MRL elevators allows for more efficient use of space and reduces the overall cost of the elevator system.
