Machine Room Less (MRL) Elevator drives offer

Machine such as a higher energy efficiency, low

weight, and more design freedom and better

utilization of hoist-way space. MRL drives have emerged as the superior choice in most high rise

applications. Currently a majority of MRI- drives

are mounted on a guide rail spanning beam which forces safety and stabilization components to act as load bearing component and degrades ride quality. The MRI- drives are also difficult and costly to inspect and maintain if located in such a configuration. Alternate methods of mounting MRI- drives on hoist-way spanning I beams if utilized can eliminate eccentric hauling leading to

better utilization of guide rails and an improved

ride quality. A hoist-way spanning support configuration also aids in decreasing inspection and maintenance costs by improving ease of access and increasing safety. Thus a properly located MRI- drive can provide best possible operating parameters for a high rise application

with lower costs of inspection and maintenance over the elevator lifetime.
