PROBLEM TO BE SOLVED: To realize efficient maintenance inspection operation.SOLUTION: An escalator 1 of one embodiment lifts a coupled driving wheel cart 24 to the upper side in vertical direction from a rail 26. A coupled driving wheel cart lifting jig 100 comprises a support plate 101 and a jack up bolt 102. The support plate 101 is inserted between a plurality of rollers 25 between the rail 26 and the coupled driving wheel cart 24. The jack up bolt 102 is screwed with a bolt hole 101c on the support plate 101. According to the screwed condition, projection volume of the lower end part 102b projecting from the support plate 101 is changed. In a screwed state with the bolt hole 101c, the lower end part 102b is opposed to the upper surface of the rail 26. By screwing the jack up bolt 102 into the bolt hole 101c, the lower end part 102b of the jack up bolt 102 presses a base part 26a of the rail 26, thus the coupled driving wheel cart 24 is lifted to the upper side in vertical direction.SELECTED DRAWING: Figure 1

    【課題】保守点検作業をより効率的に行うこと。【解決手段】実施形態に係るエスカレータ1は、従動輪台車24をレール26から鉛直方向上側に持ち上げる。従動輪台車持上治具100は、支持プレート101と、ジャッキアップボルト102を備える。支持プレート101は、レール26と従動輪台車24との間で、複数のローラー25間に挿入される。ジャッキアップボルト102は、支持プレート101のボルト孔101cと螺合され、螺合状態によって下端部102bが支持プレート101から突出する突出量が変化し、ボルト孔101cと螺合した状態で下端部102bがレール26の上面と対向する。ボルト孔101cにジャッキアップボルト102を螺合することで、ジャッキアップボルト102の下端部102bがレール26のベース部26aを押圧し、従動輪台車24が鉛直方向上側に持ち上げられる。【選択図】図1
