抓斗桥式起重机的典型故障分析与处理

Analysis and handling of typical faults of bridge-type grab crane

依照《起重机设计规范》和起重机结构计算原理,对抓斗桥式起重机出现的几个障碍原因进行分析,进行技术改造,解决了生产中实际遇到的问题。经多年运行实践证明,改造后的抓斗桥式起重机各项工作性能均达到现行设计指标,改造方案对消除起重机缺陷有一定的借鉴意义。

According to Design Rules for Cranes and crane structure calculation principle,the paper analyzes the causes of several faults in bridge type grab crane,and solves actual problems in production through technical improvements.Several years of operation practice prove that the working performance of the improved bridge type grab crane meets the current design indicators,so the improved scheme is of certain reference to elimination of defects in crane.
