MRL lift stands for Machine Room-Less Lift. For this type of life, all of the lift’s machinery is contained in or adjacent to the lift shaft, rather than in a separate room. MRL lifts have all of the same components as a traditional lift, just in a different configuration.
The motor is one of the largest and most important parts of your lift. In a machine roomless lift, the motor is usually smaller than in a traditional lift and is located at the top of the lift shaft (sometimes called the hoistway) or at the bottom of the lift pit.
Connected to the motor, you’ll find the traction sheave, which drives the hoisting ropes and cables. Depending on the configuration of your MRL lift, this may also be at the top or bottom of the lift shaft.
Elements like the lift hoisting ropes, counterweight, electronic controller, and safety features like brakes and limit switches are all also in place in the lift shaft. This might be at the top or bottom of the lift shaft or recessed into the lift shaft wall.
For this to work, the components of an MRL lift are generally smaller than a lift with a machine room, allowing them to be tucked away in or next to the lift shaft.
