To provide a lift rope measuring system which easily derives a rope diameter of a rope supporting a moving body.SOLUTION: A lift rope measuring system of an embodiment comprises: a pair of detecting members which are provided at either one of a moving body supported by a rope being wound around a sheave and moving up and down within a hoistway by rotation of the sheave and a hoistway, and are arranged with an interval in a lifting/lowering direction of the moving body; a detecting part which is provided at the other one of the moving body and the hoistway and detects each of the pair of detecting members; a specifying part which specifies a pair of timings at which the detecting part passes through each position of the pair of detecting members based on a detection result of the detecting part; and a calculating part which calculates a rope diameter of the rope based on the interval and the rotation quantity of the sheave between the pair of specified timings.SELECTED DRAWING: Figure 3

    【課題】移動体を支持するロープのロープ径を容易に導出する。【解決手段】実施形態の昇降機用ロープ計測システムは、シーブに巻き掛けられたロープによって支持され、シーブの回転によって昇降路内を昇降する移動体、および、昇降路の何れか一方に設けられ、移動体の昇降方向に間隔を隔てて配置された一対の検出部材と、移動体および昇降路の他方に設けられ、一対の検出部材の各々を検出する検出部と、検出部の検出結果に基づいて、一対の検出部材の各々の位置を検出部が通過した一対のタイミングを特定する特定部と、特定された一対のタイミングのタイミング間におけるシーブの回転量および上記間隔に基づいて、ロープのロープ径を算出する算出部と、を備える。【選択図】図3
