升降货梯是一种比较安全的起重设备，说道之所以安全是升降货梯具有安全防坠、超载、停电等安全保护装置。那么升降货梯防坠系统有哪些作用呢？

升降货梯http://m.iyunsun.com/防坠系统是作为重要的系统之一，它不仅仅关系到人身的安全，更关系到周围群众的人身财产安全，所以我们一定要把防坠系统做好检测，这是我们最为重要的一点，所以我们一定要安装一个防坠安全器来保障我们的安全。
Cargo lifter fall arrest system is one of the important system, it is not only related to personal safety, but also related to the personal and property safety of the people around, so we must take the fall protection system to do testing, which is our most important a little, so we must install an anti-fall safety device to protect our security.

升降货梯http://m.iyunsun.com/齿轮锥鼓形渐进式防坠安全器的工作原理是:当防护目标下行的运行速度达到标定的动作速度时，其离心式限速装置的甩块移位(相当棘爪)，带动锥鼓(相当棘轮)向制动带运动、接触并产生制动力矩，同时碟形弹簧组被压缩，测量压缩量的大小，通过计算可判断其额定制动载荷时的制动距离。
Cargo lifter gear tapered drum progressive anti-fall safety device works: When the guard reached the target operating speed downlink calibration operation speed, swing speed limiting device block its centrifugal shift (rather pawl),driven cone drum (rather ratchet) to the brake belt movement, contact and generates braking torque, while the coned disc spring stack is compressed, the size of measuring the amount of compression, can be determined by calculating the braking distance when the rated load of the brake.
