安庆北站20t/10tU型门式起重机安装完毕后,按照规定先由当地安全检测机构进行检测,测得主梁有效悬臂处垂直静挠度不符合根据相关标准,故判定该起重机的主梁质量为不合格产品,但该结论存在争议。通过在复检时对现场测量所得静挠度数据进行分析修正,消除非主梁静挠度因素在数据中的影响,使该主梁最终判定为合格产品。
Anqing North Station 20t / 10tU gantry crane installation is completed, according to the provisions of the local safety testing agencies to detect the effective girder cantilever at the vertical static deflection does not meet the relevant standards, it is determined that the quality of the main girder crane is not Qualified product, but the conclusion is controversial. By analyzing and correcting the static deflection data measured at the scene during the re-inspection, the influence of the static deflection of the non-main beam in the data is eliminated, so that the main beam is finally judged as the qualified product.
