箱体电动单梁的大劲板焊接形式的研究

摘要

More and more European single box girders are applied in practice,but it's necessary to determine whether the stiffener is welded with either upper cover or lower cover for the European single box girder.The paper describes the test being performed to solve this problem,analyze the test data,and initially get the conclusions,with expectation of the effect of further research on energy conservation and economy of the crane.%越来越多的欧式箱体单梁在实际中应用，但对于欧式单梁起重机，存在大劲板与上盖板焊接还是与下盖板焊接的问题。针对该问题进行了实验，分析了实验数据，并初步得出相关结论，同时展望进一步研究对起重机节能和经济性的影响。
