塔式起重机吊钩超速保护器的研制

Manufacture of electronic formula lifting hook overspeed protector on tower crane

在对塔式起重机吊钩超速坠落产生原因进行大量分析研究基础上,利用塔式起重机工作的机械原理并采用计数装置控制塔式起重机电路的方法设计开发了一种防止吊钩超速坠落的保护装置,有效制止了因吊钩超速坠落引起的工程事故。

Based on a great deal of analytical investigation about the causation of lifting hook overspeed purler, avail oneself of the theory of machiness and counter unit to control the crane electrocircuit, it provides a sort of electronic formula lifting hook overspeed protector. It can availably hold out engineering accident from lifting hook overspeed purler.
