International Classification:

B66B 7/00
B66B 7/06

US Classification:

187411

Abstract:

A suspension and transmission device for use with an elevator system comprises one or more strips that provide load carrying, transmission or traction, and load carrying redundancy or safety functions for the elevator system. In one version a single strip comprised of polymer and composite materials provides these functions. In another version multiple strips comprised of polymer and composite materials provide these functions. In another version, a strip comprises a hollow interior portion. In another version one or more strips incorporate materials that can be detected when using the strip to monitor the condition of the one or more strips.

International Classification:

B66B 5/00
B66B 3/00

Abstract:

A system and method relate to magnetic hoisting member monitoring in an elevator system having an elevator car, a hoisting motor, and a magnetic hoisting member. A monitoring system is used that includes a magnetic field producer, a giant magneto-resistance sensor, a housing unit, and an indicator system. The housing unit is structured to position the magnetic hoisting member of the elevator system relative to the magnetic field producer and the giant magneto-resistance sensor.

B66B 11/00

Abstract:

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.
