Abstract
A method for installing an elevator drive machine in a machine room-less elevator system is provided. A drive machine assembly is fastened to a counterweight. The counterweight is then lifted vertically along a set of counterweight guide rails to the top of the hoistway. There, the drive machine assembly is mounted to the ends of the counterweight guide rails. Once in place, the drive machine assembly is then disconnected from the counterweight.
