A Machine Room-Less (MRL) Elevator is a type of elevator system that operates without the need for a traditional machine room. Unlike conventional elevators that require a dedicated space above or adjacent to the shaft to house the motor and control equipment, MRL elevators integrate these components directly within the hoistway—typically at the top of the shaft or within a compact control cabinet nearby.
MRL elevators use a gearless traction system powered by a permanent magnet motor, making them energy-efficient and space-saving. They are ideal for mid-rise residential or commercial buildings where space constraints or architectural design limit the inclusion of a machine room. MRL systems offer smoother rides, quieter operation, and reduced energy consumption compared to older hydraulic or geared traction systems.
