An elevator that does not have a separate machine room is often abbreviated to M.R.L which stands for Machine Room Less and it is a type of operating system that can be applied to both traction and hydraulic lifts. Although the machine room was once considered the most important part of a functioning elevator, modern developments have allowed engineers to design a system that does not rely on them. Read on as we go over everything there is to know…
The History of MRL Lifts
A British elevator company known as Pickerings are credited with the invention of the first Machine Room Less elevator during the 1950’s, however the Econolift was discontinued during the mid-70’s. With this said, the design made way for Kone, the fourth largest elevator company in the world, to create the Kone MonoSpace system which utilised a now signature hoisting machine called the EcoDisc. Over the years, there have been many M.R.L elevator developments from many lift companies including Schindler in 1997, Toshiba in 1998 and even Otis in 2000.
Traction vs Hydraulics
In traction elevator systems, the machine room is traditionally placed on the very top floor of a building, however M.R.L designs place the hoisting machine inside the elevator shaft itself or in the basement and the motor is crafted as a permanent magnet. This design makes maintenance much easier to carry out and saves a lot of space as the machine room is often the largest part of a traction elevator. In a similar fashion, hydraulic elevators with M.R.L technology place the machinery in the elevator pit and a controller is installed on the wall where it can be easily accessed, thus reducing the time of an installation, the price of an investment and the amount of space that is required.
The Benefits of MRL Systems
Since elevators that remove the need for a machine room are much smaller, they are widely renowned for their ability to save space. After all, many properties are unable to invest in a traditional traction or hydraulic lift because they simply do not have the room. In addition to this, the smaller size of an M.R.L elevator can reduce the costs of electricity and save property owners up to 70% of their usage.
Here at Elevators Ltd, we know how important it is to take the size of a property into consideration during an elevator investment. After all, the machine room is notoriously known for taking up a lot of space. Luckily, M.R.L systems have removed the need for their implementation which helps reduce installation costs and saves vital space.
