重慶升降機限速器通常安裝在升降機機房或井道頂部，限速繩的張緊輪安裝在井道底坑。限速繩繞經限速器輪和張緊輪形成一個全封閉環路，兩端通過繩頭連接架安裝在轎廂梁上。那么升降機限速器有哪些作用呢？

1、當超速達到限速器電氣動作的速度值時，限速器安全開關動作，斷開控制回路，升降機主機停止運轉，同時抱閘釋放，貨梯制停。
When a speeding freight elevator to reach the governor of Zhejiang Electric movement speed value, speed limiter safety switch operation, disconnect the control loop, lift the host stops running, while the brake is released, Zhejiang freight elevator system to stop.

2、貨梯沒有被有效制動繼續超速達到限速器機械動作的速度值時，限速器機械部件動作，使限速器旋轉部件停轉或使限速器夾繩機構動作，限速器鋼絲繩借助與繩輪的摩擦力或夾繩機構的制動力被夾緊，從而與貨梯轎廂產生相對運動。
Zhejiang Huoti not effectively reach the governor overspeed brake continued mechanical action of the speed value, the governor mechanical parts action, so that the governor stopped rotating parts or to the governor rope clamp mechanism is operated by means of the governor rope clamped with friction or braking mechanism sheave rope clip, resulting in relative motion and Zhejiang freight elevator car.

3、貨梯被夾緊的限速繩提拉起安裝于轎廂架上的安全鉗連桿系統，使安全鉗鍥塊與升降機導軌面的間隙不斷減小，直到把轎廂夾持在導軌上。
Zhejiang clamped speed freight elevator installed in the car frame pull-rope safety gear linkage system that allows security clamp wedge block and lift the rail surface of the gap continues to be reduced until the car is clamped on the rail.
