PROBLEM TO BE SOLVED: To modify an existing governor tensioner to a governor tensioner which satisfies the newest earthquake resistance standard and a user specification while utilizing an existing governor tensioner main body and a weight.SOLUTION: This aseismatic modification method of a governor tensioner applies modification for reinforcing earthquake resistance to a governor tensioner 14 having a tensioner sheave 15 to which a governor rope 12 of a speed governor 8 of an elevator is wound, and a weight 16 for imparting necessary tension to the governor rope 12. The tensioner sheave 15b of the governor tensioner and the weight 16 are utilized without change, and the modification of the earthquake resistance is applied to the existing governor tensioner 14 in a pit at a lowermost part of a hoistway in a state that the tensioner governor 15 is hung by the governor rope 12.SELECTED DRAWING: Figure 2

    【課題】既存のガバナテンショナー本体や、おもりをそのまま流用しながら、最新の耐震基準と客先仕様を満たすガバナテンショナーに改造することができるようにする。【解決手段】本発明の実施形態に係るガバナテンショナーの耐震改造方法は、エレベータの調速機8のガバナロープ12が巻き掛けられるテンショナーシーブ15と、ガバナロープ12に必要な張力をかけるウェイト16と、を有するガバナテンショナー14に耐震性を強化する改造を実施する。に既設のガバナテンショナーのテンショナーシーブ15およびウェイト16をそのまま流用し、テンショナーシーブ15をガバナロープ12で吊った状態で、昇降路最下部のピット内で耐震強化の改造を既設のガバナテンショナー14に加える。【選択図】図2
