Rack-and-Pinion Gear-Drive System for Spires of Steel

摘要

"Spires Or Steel," which was published in the June 2006 issue of ELEVATOR WORLD, described the application of traction-elevator technology to provide access to broadcast towers standing as tall as 2,000 feet above ground level. While this elevator technology has been successfully utilized in towers for over five decades, a recent innovation has made rack-and-pinion-drive elevators viable alternatives for these structures as well.
