The ascending car overspeed protection (also known as ACOP) is a special device installed in the traction elevator, to stop the elevator in case of the elevator car overspeed upwards to the top of the shaft[1].
Notes and references[]
- ↑ 但是,早年設計並沒有預料到升降機會向上超速。若制動系統發生問題,加上升降機重量(機箱重量連同負載)比對重鉈輕,便有機會向上超速,最終因沒有適當保護裝置而撞向井道頂。, Facebook page: hkelev.com.
