MECHINE ROOM LESS (MRL)

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 then 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.
Benefits:
Saved space by placing the compact, gearless machine directly in the elevator staff.
No need for the roof top machine room which lowers building construction costs.
Gearless machine and counter weight configuration of MRL increase energy efficiency and provides a smooth, quiet ride.
