Machine Room Less Elevator

Machine room less elevators are traction elevators that do not have a dedicated machine room above the elevator shaft. The machine sits in the override space and is accessed from the top of the elevator cab when maintenance or repairs are required. The control boxes are located in the control room that is adjacent to elevator shaft on the highest landing and within 150 feet of the machine.

Machine room less elevators have a maximum travel distance of upto 150 feet and can travel at speed up to 300 feet-per minute. Mrl elevators are comparable to geared traction elevators in terms of initial and maintenance costs, but they have relatively low energy consumption compared to geared elevators.

Machine room less elevators are becoming the most popular choice for mid-rise buildings where the travel distance is upto 250 feet. They are energy efficient, require less space, and their operation and reliability are on par with gear-less traction elevators.
