PROBLEM TO BE SOLVED: To provide an elevator pit ladder capable of simply and surely fixing the pit ladder at a storage position and a work position without providing any hole in a pit floor, and an elevator safety operation system equipped with the same.SOLUTION: A pit ladder 32 is provided in a pit P vertically stored in a storage position X along the wall surface W of the lower side of an entrance 20 at an uppermost floor, and rotated in the vertical state to be pulled out to a work position Y, and includes support cylinders 38a and 38b fixed to a vertical column 36a, a support shaft 39 having one end inserted into the support cylinders 38a and 38b and fixed to the floor of the pit P, and a rotation stop 32a penetrating the support cylinder 38b and the support shaft 39. The support shaft 39 is set as the rotational center of the pit ladder 32, and the rotation stop 32a penetrates the support cylinder 38b and the support shaft 39 in the pulled-out state of the pit ladder 32 to the work position Y to fix the rotation of the pit ladder 32.SELECTED DRAWING: Figure 1

    【課題】ピット床に穴を設けなくとも収納位置および作業位置でピット梯子を簡単かつ確実に固定することができるエレベータピット梯子、および、これを備えたエレベータの安全運転システムを提供する。【解決手段】ピット梯子32は、最下階における乗降口20の下側の壁面Wに沿った収納位置Xに縦向きに収納され、縦向きのまま回転して作業位置Yに引き出されるピットPに設けられたピット梯子32であり、縦柱36aに固定された支持筒38a,38bと、支持筒38a,38bに挿入され一端がピットPの床に固定された支持軸39と、支持筒38b及び支持軸39を貫通する回り止め32aとを含み、支持軸39がピット梯子32の回転中心となり、回り止め32aはピット梯子32が作業位置Yに引き出された状態で支持筒38bと支持軸39とを貫通してピット梯子32の回転を固定する。【選択図】図1
