A machine room-less (MRL) passenger elevator is a type of elevator that does not require a separate machine room for its hoisting machinery. Instead, the machinery is typically housed within the elevator shaft, often at the top, or in some cases, within the hoistway. This design saves valuable building space and can simplify construction. MRL elevators can be either traction or hydraulic and utilize advanced controllers for precise operation and energy efficiency.  

A panoramic MRL (Machine Room-Less) elevator combines the features of a panoramic elevator, with its glass walls offering views, and an MRL design, which eliminates the need for a separate machine room, resulting in a more space-efficient and energy-saving solution. These elevators are popular for their aesthetic appeal and modern design, often found in commercial buildings, hotels, and residential spaces. The MRL system also allows for more flexible building designs and potentially lower construction costs.  

A Machine Room-Less (MRL) elevator for homes eliminates the need for a separate machine room, instead housing the machinery within the hoistway or directly above the elevator shaft. This space-saving design is achieved by using gearless traction machines and compact controllers, often making them ideal for residential applications where space is at a premium. MRL elevators can offer smooth, quiet operation and energy efficiency, making them a popular choice for modern homes.
