PROBLEM TO BE SOLVED: To continue an emergency operation without affecting an operation of an elevator, even in the case where a motor for hoist is flooded by water discharge and the like during fire fighting.SOLUTION: An emergency elevator without machine room includes: a main motor 8 for driving a main sheave 6 installed on a hoistway bottom part side of a building in which the elevator is installed; an electromagnetic clutch 16 for connecting/disconnecting connection between the main sheave 6 and the main motor 8; a sub motor 12 for driving the sub sheave 10 installed in a hoistway further upward than an uppermost floor level of the building; a flooding sensor 18 installed on the hoistway bottom part side; and a sub motor control part 22 for, in the case where flooding to the hoistway bottom part side is detected by the flooding sensor 18, disconnecting the connection between the main sheave 6 and the main motor 8 by the electromagnetic clutch 16 and operating an elevator car by a sub motor 12.SELECTED DRAWING: Figure 1
【課題】 消火活動中に放水等により巻上機用のモータが浸水した場合にあっても、エレベータの運転に影響を与えることがなく、非常運転を継続する。【解決手段】 エレベータが設置された建屋の昇降路底部側に設置されたメインシーブ6を駆動するメインモータ8と、メインシーブ6とメインモータ8との連結を入り切りする電磁クラッチ16と、建屋の最上階フロアレベルよりも上の昇降路内に設置されたサブシーブ10を駆動するサブモータ12と、昇降路底部側に設置された浸水センサ18と、浸水センサ18により昇降路底部側への浸水が検出された場合には、電磁クラッチ16によるメインシーブ6とメインモータ8との連結を切離し、サブモータ12により乗りかごを運転するサブモータ制御部22とを具備する。【選択図】図1
