To provide an elevator capable of imparting a necessary weight to a rope even during an emergency operation in which the inside of a hoistway is flooded.SOLUTION: An elevator comprises: a car that travels vertically; a tensioning device that is suspended on a rope in order to apply tension to the rope; a water level detector that detects that the water level in the hoistway reaches a specified level; and a processing unit that sets the car in a normal operation mode when the water level detection unit does not detect the water level, and sets the car in an emergency operation mode when the water level detection unit detects the water level. The mass of the tensioning device is the mass that can apply a required weight to the rope even during the emergency operation.SELECTED DRAWING: Figure 1

    【課題】 昇降路内が浸水した状態の非常運転時でも、ロープに必要な重量を付与することができるエレベータを提供する。【解決手段】 エレベータは、上下方向に走行するかごと、ロープに張力を付与するために、ロープに吊り下げられる張力付与装置と、昇降路内の水位が所定の水位に達することを検出する水位検出部と、水位検出部が水位を検出しない場合に、かごの走行を正常運転にし、水位検出部が水位を検出した場合に、かごの走行を非常運転にする処理部と、を備え、張力付与装置の質量は、非常運転時でも、ロープに必要な重量を付与することができる質量である。【選択図】 図1
