重庆升降机限速器通常安装在升降机机房或井道顶部，限速绳的张紧轮安装在井道底坑。限速绳绕经限速器轮和张紧轮形成一个全封闭环路，两端通过绳头连接架安装在轿厢梁上。那么升降机限速器有哪些作用呢？

1、当超速达到限速器电气动作的速度值时，限速器安全开关动作，断开控制回路，升降机主机停止运转，同时抱闸释放，货梯制停。
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、货梯没有被有效制动继续超速达到限速器机械动作的速度值时，限速器机械部件动作，使限速器旋转部件停转或使限速器夹绳机构动作，限速器钢丝绳借助与绳轮的摩擦力或夹绳机构的制动力被夹紧，从而与货梯轿厢产生相对运动。
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、货梯被夹紧的限速绳提拉起安装于轿厢架上的安全钳连杆系统，使安全钳锲块与升降机导轨面的间隙不断减小，直到把轿厢夹持在导轨上。
