Machine Room-Less (MRL) elevators include machinery and equipment into the hoistway or closets, doing away the need for a separate machine room. This system employs a smaller sheave than conventional geared and gearless elevators.
Machine Room-Less (MRL) elevators include machinery and equipment into the hoistway or closets, doing away the need for a separate machine room. This system employs a smaller sheave than conventional geared and gearless elevators.
The reduced sheave size, together with a newly designed machine (Permanent Magnet Synchronous Motor PMSM) allows the machine to be mounted within the hoistway itself, eliminating the need for a bulky machine room on the roof.
