PROBLEM TO BE SOLVED: To accurately measure a wear amount of a drive chain of a movement hand rail.SOLUTION: The invention is provided on an escalator for example, a control device 17 for performing travel control of whole body comprises an arithmetic unit 23 for performing arithmetic of a wear amount of a drive chain. The arithmetic unit 23 comprises: a first arithmetic part for performing arithmetic of travel resistance F0 of a whole escalator during no-load time; a second arithmetic part for performing arithmetic of travel resistance Ft of a movement hand rail 1 during an encoder detection time point; a third arithmetic part for performing arithmetic of travel resistance Ft0 of the hand rail 1 during no-load time, based on the travel resistance F0 and travel resistance Fs by step; a fourth arithmetic part for performing arithmetic of increased travel resistance ΔFt of the movement hand rail 1 based on the above-mentioned travel resistance Ft and travel resistance Ft0; a fifth arithmetic part for performing arithmetic an integrated value ΣΔFt by integration of the travel resistance ΔFt; and a sixth arithmetic part for performing arithmetic of a wear amount of the drive chain, based on a number of bending Σn of the drive chain, and the integrated value ΣΔFt.

    【課題】移動手摺の駆動チェーンの摩耗量を精度良く測定する。【解決手段】本発明は、例えばエスカレータに設けられるものであり、全体の走行制御を行う制御装置17が、駆動チェーンの摩耗量を演算する演算装置23を備えている。この演算装置23は、無負荷時のエスカレータの全体の走行抵抗F0を演算する第1演算部と、エンコーダ検出時点における移動手摺1の走行抵抗Ftを演算する第2演算部と、走行抵抗F0とステップによる走行抵抗Fsとから無負荷時の移動手摺1の走行抵抗Ft0を演算する第3演算部と、前述の走行抵抗Ftと走行抵抗Ft0とから、移動手摺1の増加した走行抵抗ΔFtを演算する第4演算部と、走行抵抗ΔFtを積算して積算値ΣΔFtを演算する第5演算部と、駆動チェーンの屈曲回数Σnと、積算値ΣΔFtとから駆動チェーンの摩耗量を演算する第6演算部とを含んでいる。【選択図】図2
