Abstract
The model for girder erection crane is built using MIDAS to analyze the load-carrying and deformation of the girder-erecting machine under the working conditions of full-load,maximum front suspending arm,and complete verti-cal displacement.The girder crane can have the girder section adjusted in vertical,horizontal,and longitudinal direction by the frequency-conversion and hydraulic technologies,which is suitable for hoisting in side-span closure section,mid-span closure section,standard girder section,and transition girder section.关键词
