PROBLEM TO BE SOLVED: To enable an inspection operation without excessively raising a car, when inspecting a brake configured in double of an elevator, and to prevent unintended brake release at inspection time.SOLUTION: In a brake control device 250 for maintenance inspection, two pieces of brakes 230x, 231y brake an electric motor 102 for driving a car 103. At the maintenance inspection time, brake coils 232x, 233y release a brake operation of the brakes. At the brake coils, the brake control device 250 is connected. The brake control device includes: constantly-closed contact points 213x, 214y connected to the brakes respectively; a brake safety circuit 224 connected to the constantly-closed contact points and operating the brake coils; a connection part 207 connected to the brake safety circuit and switching first and second circuits which the safety circuit has; and brake release means 212 detachably connected to the connection part and instructing the switching of the connection part.

    【課題】エレベーターの2重に構成されたブレーキを点検するときに、乗りかごを過昇させなくとも点検動作を可能にするとともに、点検時の意図しないブレーキ開放を防止する。【解決手段】保守点検用ブレーキ制御装置250は、乗りかご103を駆動する電動機102を2個のブレーキ230x、231yが制動する。保守点検時に、ブレーキの制動動作をブレーキコイル232x、233yが開放する。ブレーキコイルには、ブレーキ制御装置250が接続されており、ブレーキ制御装置は、ブレーキのそれぞれに接続する常閉接点213x、214yと、常閉接点に接続されブレーキコイルを動作させるブレーキ安全回路224と、ブレーキ安全回路に接続され安全回路が有する第1、第2の回路を切り替える接続部207と、接続部に着脱可能に接続され接続部の切り替えを指示するブレーキ開放手段212を備える。【選択図】図2
