MRL Elevators
Machine-room-less elevators include machinery and equipment into the hoistway, doing away the need for a separate machine room. The reduced sheave size, together with a redesigned machine, allows the machine to be mounted within the hoistway itself – eliminating the need for a bulky machine room on the roof.
The machine room-less elevator is the result of technological advancements that often allow a signficant reduction in the size of the electric motors used with Traction equipment. These newly designed permanent magnet motors (pmm) allow the manufacturers to locate the machines in the hoistway overhead.
