Abstract

See full text

One or more drum winches wind and unwind flat suspension members to raise and lower an elevator car within a hoistway. Support structures on opposite sides of the hoistway support the winch(es). The flat suspension member may be attached to a termination point on the elevator car. In other examples, a single flat suspension member is simultaneously taken up by a winch on either side of the hoistway, passing down the sides and around the bottom of the elevator car. In a third example, a single winch takes up and lets down the flat suspension member, which passes down the side of the elevator car, around the bottom corners using deflector sheaves, and up the opposite side to a termination point mounted on one of the support structures. The profile ratio of the flat suspension member is at least about 10:1, 50:1, or at least about 90:1.
