Mitsubishi Electric machine-room-less elevator quality is second to none, and our Diamond Trac® gearless elevator provides technological advances that deliver a world-class ride, maximum MRL life cycle and exceptional reliability — with an average of less than one callback per elevator per year with our maintenance plans. We also provide monitoring services for our machine-room-less elevators. 

How MRL elevators work:

Machine-room-less elevators utilize a gearless traction machine located in the hoistway. The use of a counterweight assists the machine in turning the elevator sheave, which moves the cab through the hoistway. Most commonly seen in hotels, apartments, mixed-use buildings and commercial offices, MRL elevators can handle 2 to 25 stops (with a typical capacity of 2,100 to 5,000 lbs.) and feature flexible design. Large capacities (4,000 lbs. and above) can accommodate heavier cab finishes.
