This paper provides an overview of the new GeN2 machine roomless elevator system from Otis. In particular, details about the revolutionary new coated steel belt technology are discussed. Qualification of this new component is reviewed with emphasis on durability of the steel cord and polyurethane jacket. Examples and results of breaking load tests, bending fatigue and traction durability tests, and environmental tests (including low and high temperatures) are reviewed. The advantages inherent in this new lifting technology are reviewed and up-to-date successes are provided.
