摘要
对投入运行约10年的桥架结构的两个端梁局部产生了一些肉眼可见的裂纹的西班牙进口的450 t×21.4 m的冶金桥式起重机的,端梁受力状况进行了计算,并对整体桥架金属结构在动态运动中的受力进行测试及分析,结合测试分析的结果为该起重机的两个端梁结构采取整改措施.
The End beams of the bridge in the metallurgy Eot crane, which was made in Spain for 450t 21. 4m 10 years ago, showed a lot of cracks. The stress in the End Beams is calculated to eliminate hidden troubles. The dynamic stress and strain on the bridge is tested and analyzed and measures to deal with the problem are proposed.
