Description
実施の形態1.
図1は、この発明の実施の形態1によるエレベータのかごを示す正面図である。また、図2は、図1のエレベータのかごを示す平面図である。図において、昇降路内には、水平方向について互いに対向する一対のガイドレール1が上下方向に沿って設置されている。一対のガイドレール1間には、かご2が配置されている。かご2は、複数本の懸吊体3により昇降路内に吊り下げられている。懸吊体3としては、例えばロープやベルト等が用いられている。懸吊体3は、昇降路内に設けられた駆動装置である巻上機の駆動綱車(図示せず)に巻き掛けられている。かご2は、巻上機の駆動綱車の回転により、各ガイドレール1に案内されながら昇降路内を上下方向へ移動される。
このようにして、非常止め装置15をかご2に取り付ける。
実施の形態1では、かご2に対する制動力の大きさを安定的に維持する次第ぎきの非常止め装置本体33が非常止めフレーム31に設けられているが、かご2に対する制動力を急激に発生してかご2をほとんど瞬時に停止させる早ぎきの非常止め装置本体を非常止めフレーム31に設けてもよい。
