Patent number: 11718505Abstract: A suspension member for suspending and/or driving an elevator car of an elevator system includes a plurality of tension members extending along a length of the suspension member including a plurality of fibers extending along the length of the suspension member bonded into a polymer matrix. A jacket substantially retains the plurality of tension members. The suspension member is configured to be deformed at a suspension member end to allow for installation of the suspension member end into a termination assembly of the elevator system. A method of installing a suspension member of an elevator system into a termination assembly includes deforming a suspension member end and reforming it to a selected shape, inserting the suspension member end into the termination assembly and curing and/or hardening it, and applying a load thereto or to the socket or the wedge to secure the suspension member end in the termination assembly.Type: GrantFiled: July 16, 2020Date of Patent: August 8, 2023Assignee: OTIS ELEVATOR COMPANYInventors: Richard N. Fargo, Mark R. Gurvich, Richard J. Ericson, Douglas E. Logan, John P. Wesson, David Wayne Mckee, Wenping Zhao

Patent number: 10399820Abstract: A system for determining stiffness of an elevator system tension member includes a landing floor indicator to transmit a landing floor signal of an elevator car to a stiffness estimator, and a car position encoder to transmit a car position signal of the elevator car in a hoistway to the stiffness estimator. A machine position encoder transmits a machine position signal to the stiffness estimator. The tension member is operably connected to the machine to move the elevator car along the hoistway. A load weight sensor is located at the elevator car to transmit a load weight signal of the elevator car to the stiffness estimator. The stiffness estimator utilizes at least the landing floor signal, the car position signal, the machine position signal and the load weight signal to calculate an estimated stiffness of the tension member.Type: GrantFiled: February 19, 2014Date of Patent: September 3, 2019Assignee: OTIS ELEVATOR COMPANYInventors: Randall Keith Roberts, YiSug Kwon, David Wayne Mckee, Richard L.

Patent number: 9663328Abstract: A belt for suspending and/or driving an elevator car includes a plurality of wires arranged into a plurality of cords. The plurality of cords includes one or more inner cords located at an innermost portion of the belt relative to a lateral end of the belt and one or more outer cords located laterally outboard of the one or more inner cords. The one or more outer cords have a construction distinct from the one or more inner cords. A jacket substantially retains the plurality of cords.Type: GrantFiled: November 10, 2011Date of Patent: May 30, 2017Assignee: OTIS ELEVATOR COMPANYInventors: Brad Guilani, Mark Steven Thompson, Kyle B.

Publication number: 20110114908Abstract: An exemplary method of making a first component for contacting another component includes applying a wear and corrosion resistant material layer onto a surface of the first component. The wear and corrosion resistant material layer is then roughened subsequent to having been applied to the surface. A component comprises an exemplary elevator sheave that includes a metallic body having a sheave surface that is adapted to contact an elevator tension member. A corrosion resistant material layer on the sheave surface has a thickness that is greater than about 5 microns.Type: ApplicationFiled: July 3, 2008Publication date: May 19, 2011Inventors: Richard N.
