Elevador sem casa de máquinas (MRL)

What is MRL Elevator?

A elevador sem casa de máquinas, also known as an MRL elevator, is a type of elevator that does not need a separate room for machinery. Machine room-less elevators use a traction system, allowing the machinery to be within the hoist-way or the elevator car shaft.

Machine room-less 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.

Como funciona o elevador MRL?

Machine room-less elevators use um sistema de tração para levantar e abaixar o carro do elevador. Este sistema consiste em um motor, caixa de engrenagens e cordas ou correias. O motor gera energia para girar a caixa de câmbio, que aciona as cordas ou correias que levantam o carro. As cordas ou cintos prendem o carro e o contrapeso para equilibrar o peso do carro e dos passageiros.

The critical components of a machine room-less 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 it for passenger, freight, and service elevators.

What Are The Advantages of Machine Room-Less Elevators?

Some of the main benefits include the following:

Custo-benefício

Machine room-less elevators are more cost-effective to install. This system can make elevators more attractive if you want to save on construction costs.

Flexibilidade de projeto de construção

Machine room-less 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.

Eficiência energética

Machine room-less elevators are more energy efficient. This efficiency is due to advanced motors and control systems.

Vida útil mais longa e custos de manutenção mais baixos

Machine room-less 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.

O que é mais adequado para elevadores sem casa de máquinas? 

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 room-less elevators are typically more space-efficient than elevators with a dedicated machine room, making them a good choice for low to mid rise buildings.

Here are the differences between machine room-less elevators and machine room elevators:

Requisitos de espaço

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

Custos de instalação

Machine room-less elevators have lower installation costs than machine room elevators. They do not need the construction of a separate machine room.

Eficiência energética

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

Manutenção

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

Barulho

O ruído dos elevadores sem casa de máquinas é mais alto do que o dos elevadores com casa de máquinas.

Conforto

O conforto dos elevadores sem casa de máquinas não é tão bom quanto o dos elevadores com casa de máquinas.

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