摘　　要：文章介绍了桥式起重机主梁挠度的概念和应修标准,通过测量分析主梁下挠产生的原因,并对主梁强度进行计算,讲述了主梁下挠后实际生产中的修复原理,对预计修复后的主梁进行强度测算,提出挠度修复的具体措施。In the paper,the concept and standard of repair for bending of main beam for crane are introduced. Moreover,the principles of repair in actual production of downwarp for main beam are discussed through measuring and analyzing the causes of downwarp for main beam as well as calculating the strength of main beam. The specific measures for repairing bending are proposed finally.
