Machine Room Less (MRL) Elevator

Suppose you are looking to install an elevator in your building. You may have come across the term "MRL elevator" or "machine Room elevator." But what exactly is an MRL elevator, and how does it differ from traditional elevators? In this article, we'll delve into the concept of MRL elevators, how they work, and the advantages they offer. We'll also discuss the types of buildings suitable for MRL elevators. Ultimately, we'd compare them to their machine room (MR) counterparts.

What Is MRL Elevator?

A machine room-less elevator, also known as an MRL elevator, is a type of elevator that does not need a separate room for machinery. Instead, machine room-less elevators use a traction system. This system includes a motor, brake, and ropes or belts to lift and lower the car. This system allows the machinery to be within the hoist-way or the elevator car shaft.

MRL elevators offer a lot of building design and layout flexibility. Since it does not need a machine room, You can repurpose the space generally used for this purpose for other purposes.

How Does MRL Elevator Work?

Machine room less elevators use a traction system to lift and lower the elevator car. This system consists of a motor, gearbox, and ropes or belts. The motor generates power to turn the gearbox, which drives the ropes or belts that lift the car. The ropes or belts attach the car and counterweight to balance the weight of the car and passengers.

The critical components of an MRL elevator include the hoist-way, car, and controls. The hoist-way is the shaft that contains the elevator car and is made of steel or concrete. The car is the enclosure that carries the passengers, and the controls are the systems that regulate the operation of the elevator. In various applications, you can use MRL elevators for passenger, freight, and service elevators.

What Are The Advantages of MRL Elevators?

Some of the main benefits of using a machine room less elevator include the following:


MRL elevators are more cost-effective to install than traditional elevators. With MRL, you do not need to construct a separate machine room. This system can make MRL elevators more attractive if you want to save on construction costs.

Smaller Footprint

MRL elevators have a smaller footprint. The machinery is within the hoist-way rather than in a separate room. This is beneficial in buildings with limited space or unconventional layouts.

Energy Efficiency

MRL elevators are more energy efficient. This efficiency is due to advanced motors and control systems.

Longer Lifespan and Lower Maintenance Costs

MRL elevators have a higher upfront cost. But they tend to have lower ongoing maintenance costs and a longer lifespan. This lifespan makes them a more cost-effective option in the long run.

Building Design Flexibility

MRL elevators offer design and layout flexibility. They do not need a separate machine room, allowing the space to be used as extra floors or storage. This can be particularly useful in buildings with limited space or unconventional layouts.

What Is Best Suitable For Machine Roomless Elevators? 

Whether to use a machine room or machine roomless elevator depends on several factors, including the height of the building, the size of the shaft space, and the expected passenger traffic. Machine roomless elevators, or MRL elevators, are typically more space-efficient than elevators with a dedicated machine room, making them a good choice for low- to mid-rise buildings.

MRL elevators are suitable for various building types. You can use it in new construction projects and renovations of existing buildings. Some factors to consider when deciding if an MRL elevator is the best choice for you:

Size and Layout of The Building

MRL elevators are a good choice if you have limited space. These elevators are also suitable for high-rise or older buildings where a machine room might not be available.

Top Floor Height

MRL elevators are generally used in low to medium-rise buildings with low speeds below 1.75m/s.

To sum up, machine-room-less elevators are suitable for various high-grade office buildings, hotels, shopping malls, hospitals, convention centers, fashionable residential communities, etc.

What Is The Main Difference Between MRL Elevator and MR Elevator? 

MR elevators need a machine room for the machinery that operates the elevator. The room is above or next to the hoist-way. It contains the motors, gears, and other mechanical components that power the elevator.

Here are the differences between MRL elevators and MR elevators:

Space Requirements

MRL elevators do not need a separate machine room. They can be installed in buildings with limited space. In contrast, MR elevators need a separate machine room, which can take up valuable space in a building.

Installation Costs

MRL elevators have lower installation costs than MR elevators. They do not need the construction of a separate machine room.

Energy Efficiency

MRL elevators tend to be more energy efficient than MR elevators. The machinery is closer to the hoist-way and does not need long power cables to connect to the elevator.


MRL elevators may need more frequent maintenance than MR elevators. This maintenance is because the machinery is in the hoist-way. It is more exposed to dust and other environmental factors.


The noise of machine-room-less elevators is louder than that of machine-room elevators.


The comfort of machine-room-less elevators is not as good as that of machine-room elevators.

The choice between an MRL elevator and an MR elevator will depend on your needs and constraints. MRL elevators are a good choice for limited space or where installation costs are a concern.

In contrast, you may prefer MR elevators when energy efficiency is a higher priority.

Frequently Asked Questions

Are MRL Elevators Safe?

MRL elevators are equipped with many safety features, such as emergency stop buttons, door interlocks, over-speed governors, and so on, MRL elevators are designed to prevent accidents and ensure the safety of passengers. 

Are MRL Elevators Hydraulic?

MRL elevators can be either hydraulic or traction. Hydraulic elevators use a piston to raise and lower the elevator car. But, traction elevators use a system of ropes and a counterweight to move the car along a guide rail.

Are MRL Elevators Suitable For High-Rise Buildings?

MRL elevators are typically more suitable for low- to mid-rise buildings due to their smaller size and the fact that they do not require a separate machine room. Traditional elevators with a dedicated machine room may be a better option for high-rise buildings.

Are MRL Elevators More Expensive?

  • The cost of an MRL elevator can vary depending on many factors; 
  • The size and capacity of the elevator,
  • The type of drive system (hydraulic or traction)
  • The number of stops and landings
  • The materials and finishes used in the construction of the elevator.

How Can I Determine If An MRL Elevator Is The Best Option For My Building?

When deciding if an MRL elevator is the best choice for your building, consider the size and layout of the building, the top floor height, the expected passenger traffic, and any relevant building codes or regulations. It may also be helpful to consult with an elevator professional or engineer to determine the best fit for your specific needs.

Can MRL Elevators Be Used For Freight or Service Elevators?

Yes, MRL elevators can be used for various applications, including passenger, freight, and service elevators.

Are There Any Potential Drawbacks to Using An MRL Elevator?

Some potential drawbacks to using an MRL elevator include a higher upfront cost and potentially less capacity compared to traditional elevators with a dedicated machine room. It is important to carefully consider these factors and consult with a professional to determine the best fit for your building.

Can MRL Elevators Be Retrofitted Into Existing Buildings?

Yes, MRL elevators can be installed in existing buildings as part of a renovation project. It is important to consider the size and layout of the building, as well as any relevant building codes or regulations when determining if an MRL elevator is a suitable option for your renovation project.

How to Choose a Sightseeing Elevator?


To summarize, MRL elevators are a cost-effective and efficient choice for modern buildings. They do not need a separate machine room, have a smaller carbon footprint, and offer a smooth and quiet ride.
