Machine Room Less Product

Machine-Room-Less Elevators are Crompton 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 a control room that is adjacent to the elevator shaft on the highest landing and within around 150 feet of the machine.

Machine-room-less elevators have a maximum travel distance of up to 250 feet and can travel at speeds up to 500 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 up to 250 feet. They are energy efficient, require less space, and their operation and reliability are on par with gear-less traction elevators.

The main reason that MRL elevators have been adopted so slowly in the United States is because the building codes had provisions that didn't allow the motor to be within the hoistway. This is slowly being changed, but it is worth consulting with the local authorities before specifying an MRL elevator.
