National and local building codes did not address elevators without machine rooms. Residential MRL elevators are still not allowed by the ASME A17 code in the US. MRL elevators have been recognized in the 2005 supplement to the 2004 A17.1 Elevator Code. Today, some machine room-less hydraulic elevators by Otis and TK Elevator exist.
Since the drive system is completely housed in the elevator shaft, no machine room is required and the control system is small enough to fit into a cabinet on a wall near the elevator. For hydraulic systems with holes, the cylinder must extend to the depth of the floor corresponding to the feet of the elevator, while hydraulic systems without ...
The Kone MonoSpace for low to mid-rise buildings is the world's first machine-room-less elevator. [17] The Kone EcoSpace elevator is a machine-room-less traction elevator designed for low-rise buildings from 2 to 4 stories as an energy-efficient alternative to hydraulic elevators, and can fit in an existing hydraulic elevator hoistway.
