在门式起重机的检验中,悬臂端上翘度是一项非常重要的内容。国家质量监督检验检疫总局颁发的《起重机械监督检验规程》中规定:新安装门式起重机的悬臂上翘度为(0.9~1.4)s’/1000。在国家标准GB 50278—98《起重设备安装工程施工及验收规范》中,对门式起重机悬臂端上翘度也做了明确要求。因为轨道高低差和支腿变形等因素的影响,主梁的2个支点可能并不是位于水平位置。当主梁的水平发生变化时,悬臂端的上翘度也
In the gantry crane inspection, the cantilever end uplift is a very important content. State Administration of Quality Supervision, Inspection and Quarantine issued a “lifting machinery supervision and inspection procedures” provides: the new gantry crane cantilever tilt (0.9 ~ 1.4) s’ / 1000. In the national standard GB 50278-98 “lifting equipment installation and acceptance of norms” on the gantry crane crane cantilever side has made a clear requirement. Due to track height and leg deformation and other factors, the two main fulcrum may not be located in the horizontal position. When the level of the main girder changes, the cantilever end upturned too
