具有基于所需服役寿命的初始安全系数的电梯承载组件
摘要：
电梯系统(20)的承载组件(30)包括多个承载构件(34)，每个所述承载构件具有选定强度。所述承载构件(34)的数量及其相关强度为所述承载组件(30)提供了初始安全系数。所述初始安全系数是基于所述承载组件(30)的得到确定的所需寿命与所述承载组件(30)在所需寿命结束时的所需退出强度之间的关系而进行选择的。
摘要（英）：

A load bearing assembly (30) of an elevator system (20) includes a plurality of load bearing members (34) that each have a selected strength. The number of load bearing members (34) and their associated strengths provide an initial factor of safety for the load bearing assembly (30). The initial factor of safety is selected based upon a relationship between a determined desired life of the load bearing assembly (30) and a desired retirement strength of the load bearing assembly (30) at the end of the desired life.
