摘要
由于冶金桥式起重机的工作环境恶劣，桥架结构焊缝多，很容易产生疲劳裂纹，因此成为影响安全 使用的危险隐患。通过对多台冶金桥式起重机的检查、测试和分析表明：宽翼缘箱形梁的桥架结构使用较安全 可靠，而工字梁和窄翼缘箱形梁加辅助桁架的主梁结构则不太安全。
Overhead traveling cranes for metallurgic plants are very easy to develop fatigue crack due to its extremely harsh operation environment and the bridges with more welding seam,so there is potential hazards during their operation.Check,mea- surement and analysis of many this type of cranes indicates the wied-flange box girder is safer in use than latticed I-girder and lat- ticed narrow-flange box girder.
