Machine-roomless elevator for innovative low-and middle-rise building design

摘要

The electric-motor-drive rope system in general use for elevators requires a machine room in theupper section of the elevator hoistway, presenting a major restriction in the design of low- andmiddle-rise buildings. The elimination of this machine room would be highly beneficial for buildingowners. Toshiba has developed and commercialized the SPACEL* machine-roomless elevator. Theneed for an elevator machine room has been eliminated by developing a revolutionary new drivingsystem, as well as a new suspension structure, compact and thin control equipment, and otherfeatures.
