Abstract: An elevator car of an elevator system includes a car body, and a car frame supportive of the car body. The car frame includes two or more opposing upright assemblies, a crosshead assembly located above the car body, and a plank assembly located below the car body. A plurality of seismic retainers are located at each of the upright assemblies. The plurality of seismic retainers are configured for a non-contact relationship with a guide rail of the elevator system during normal operation of the elevator system, and configured to react guide rail loads during a sway event via contact with the guide rail.

Abstract: 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.

Abstract: A guidance mechanism for an elevator car is constructed and arranged to move along a lane defined at least in-part between two opposing first and second lane structures of a stationary structure. The guidance mechanism includes a first support structure supported by the first lane structure. The first support structure includes a first retainer face disposed between the elevator car and the first lane structure that substantially faces the first lane structure, and is spaced from the first lane structure. A first retention device of the mechanism is disposed, at least in part, between the first retainer face and the first lane structure. The first retention device is supported by the elevator car and is constructed and arranged to contact the first retainer face for limiting lateral movement of the elevator car away from the first lane structure and toward the second lane structure.

Abstract: An elevator car of an elevator system includes a car body and a car frame supportive of the car body. The car frame includes two opposing side frames, each side frame formed from a plurality of side frame segments, including two upright members and one or more upright braces connecting the two upright members, adjacent side frame segments secured to each other via a joint. A method of installation of an elevator car of an elevator system includes positioning a first side frame segment of a plurality of side frame segments adjacent to second side frame segment of the plurality of side frame segments, and securing the first side frame segment to the second side frame segment via a splice joint thereby constructing a car frame of the elevator car. One or more car bodies are installed into the car frame.

Abstract: A hoisting system is provided that includes a first hoisted object, a second hoisted object, a tension member, a first sheave, a second sheave, a drive machine, and a traction system. The tension member connects the first and second hoisted objects. The first and second sheaves contact the tension member. The drive machine is operable to rotationally drive one of the first and second sheaves. The traction system is operable to increase a total wrap angle of the hoisting system, and thus is operable to increase an available traction of the hoisting system.
Abstract translation: 提供了一种提升系统，其包括第一提升物体，第二提升物体，张力构件，第一滑轮，第二滑轮，驱动机器和牵引系统。 张紧构件连接第一和第二个提升的物体。 第一和第二滑轮接触张力构件。 驱动机器可操作以旋转地驱动第一和第二滑轮中的一个。 牵引系统可操作以增加提升系统的总包角，因此可操作以增加提升系统的可用牵引力。
