To provide an elevator derailment detection system which detects that a counterweight of an elevator comes off from a rail due to an earthquake or the like, the system enabling the derailment of the counterweight to be detected without interrupting a current interruption circuit of a conductive wire even when maintenance and inspection work is performed in a hoistway.SOLUTION: An elevator derailment detection system comprises: a wire 12 that is installed in a space having no interference with the movement space of an ascending and descending body in a hoistway and is stretched in parallel with guide rails 4, 4a for guiding the ascending and descending of a counterweight 3; a penetration detection sensor 16 that is installed on the counterweight 3 and detects whether the wire 12 penetrates through the interior; a wire contact detection sensor 17 that is installed on the counterweight and detects whether it is in contact with the wire; and derailment determination processing means that performs derailment determination processing based on signals output from the penetration detection sensor 16 and the wire contact detection sensor 17.SELECTED DRAWING: Figure 2

    【課題】地震等によりエレベータの釣合おもりがレールから外れたことを検出するエレベータの脱レール検出システムに関するものである。昇降路内で保守点検作業をする際でも、導電線の電流遮断回路を遮断すること無しに、釣合おもりの脱レールの検出が可能なエレベータの脱レール検出システムを提供する。【解決手段】エレベータの脱レール検出システムは、昇降路内を昇降する昇降体の移動空間と干渉しない空間に設置され、釣合おもり3の昇降を案内するガイドレール4,4aと平行に張架されるワイヤ12と、釣合おもり3に設置されワイヤ12が内部を貫通しているか否かを検出する貫通検出センサ16と、釣合おもりに設置されワイヤに接触しているか否かを検出するワイヤ接触検出センサ17と、貫通検出センサ16とワイヤ接触検出センサ17とから出力された信号に基いて脱レール判定処理をおこなう脱レール判定処理手段とを備える。【選択図】図2
