Embodiment Construction

[0052] Figure 1A , Figure 1B with Figure 1C Shown therein is a schematic diagram of an exemplary traction elevator system 10. The features of the elevator system 10 (e.g., guide rails, safety devices, etc.) that are not required to understand the present invention are not discussed herein. The elevator system 10 includes an elevator car 12 that is operatively suspended or supported in a hoistway 14 using one or more belts 16. One or more belts 16 interact with one or more sheaves 18 to convey around the various components of the elevator system 10. One or more belts 16 may also be connected to a counterweight 22 that is used to help balance the elevator system 10 during operation and reduce the difference in belt tension on both sides of the traction sheave.

[0053] The sheaves 18 each have a diameter 20, which may be the same as or different from the diameter of other sheaves 18 in the elevator system 10. At least one of the sheaves 18 may be a drive sheave. The drive shea...

Abstract

A belt for suspending and / or driving an elevator car includes a plurality of wires arranged into one or more cords and a jacket substantially retaining the one or more cords. Each cord includes a plurality of wires arranged around at least one non load-bearing core. An elevator system includes an elevator car and one or more sheaves. One or more belts are operably connected to the car and interactive with the one or more sheaves for suspending and / or driving the elevator car. Each belt of the one or more belts includes a plurality of wires arranged into one or more cords and a jacket substantially retaining the one or more cords. Each cord includes a plurality of wires arranged around at least one non load-bearing core.

Description

Technical field [0001] The subject matter disclosed herein relates to elevator systems. More specifically, the present disclosure relates to tensile members for elevator suspension and / or driving. Background technique [0002] The elevator system utilizes a hoisting device such as a rope or belt to propel the elevator along the hoistway, the hoisting device is operatively connected to the elevator car and conveyed on one or more sheaves, also called pulleys. Lifting belts in particular usually include a plurality of wires at least partially within the sheath material. Multiple wires are often arranged into one or more strands, and then the strands are arranged into one or more ropes. [0003] Wire layout is usually designed with at least two basic requirements (breaking strength and rope life) in mind. The total cross-sectional area of ​​the steel used in the rope is the main determinant of the breaking strength of the rope. A large number of small cross-section wires are gener...
