20080223665 | FLEXIBLE LOAD-BEARING MEMBER FOR ELEVATOR SYSTEM - A load-bearing member operable to be driven by a drive sheave in an elevator system is provided. The load-bearing member has a body defined by a thickness, a width that is greater than the thickness, and a length. The body comprises a single solid material that is uniform in the cross-section, and is sufficiently flexible to permit the member to wrap at least partially around the drive sheave of an elevator system. An elevator system is also provided that includes the aforesaid load-bearing members, a car, a counterweight and a drive sheave. The load-bearing members connect the car and counterweight to the drive sheave, and are wrapped at least partially around the drive sheave. | 09-18-2008 |
