桥式起重机作为机械制造活动与冶金工业吊运活动的基础设备,至关重要,特别是起重机主梁。一旦主梁变形,将会对生产工作产生严重影响。笔者依据现有的实践经验,以桥式起重机为研究对象,主要剖析主梁变形原因与常用的修复方法,希望可为实际应用提供帮助。 Bridge cranes as a mechanical manufacturing activities and lifting the metallurgical industry, the basic equipment, is essential, especially the crane girder. Once the main beam is deformed, it will have a serious impact on the production work. Based on the existing practical experience, the author takes the bridge crane as the research object, mainly analyzes the reason of the deformation of the main beam and the commonly used methods of repair, and hopes to provide help for the practical application.
