摘要
Abstract
The 1 0a MQ gantry crane is used to heighten the web on the railway goods yard to increase the rated load;then 1 0a gantry crane is put into service again for analysis of static and dynamic test,to work out that the maximum static stress under rated load is at the root of cantilever on the right side of the southern beam;the reconstructed main beam still has ideal strength margin,able to meet the working demand for rated load;the dynamic response at the attachment weld of cover plate on the right side of 1/4 mid-span of south beam is most sensitive,which shall be brought to the forefront,requi-ring regular inspection.关键词
