Machine Room Type Elevators
Gear-less Traction Elevators have the wheel attached directly to the motor. Gear-less traction elevators are capable of speeds up to 2,000 feet per minute and they have a maximum travel distance of around 2,000 feet so they are the only choice for high-rise applications & Some of the Low-rise Elevator Applications in Sri Lanka.
Geared traction elevators are middle of the road in terms of initial cost, ongoing maintenance costs, and energy consumption. Gear-less traction elevators have a high initial cost, medium ongoing maintenance costs, and use energy a bit more efficiently than geared traction elevators.
It is important that traction elevator ropes and sheaves are checked for wear on a regular basis. As they wear, the traction between the sheave and the cables is reduced and slippage becomes more regular, which reduces the efficiency and can become dangerous if left unchecked.
Traction elevators have height restrictions that are governed by the length and weight of the cables or ropes. New materials that are stronger and lighter, such as carbon fiber, will allow traction elevators to achieve new heights.

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 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 that the building codes had provisions that didn’t allow the motor to be within the hoistway. This is changing, but it is worth consulting with the local codes before specifying an MRL elevator.
