| Abstract: | It is presented the project of hoisting a superlong span portal frame beam,whose hoisting is very difficult due to a free span of 55 m and a very low lateral stiffness of the steel beam.Finally the double crane hoisting is chosen through comparing several schemes technically and economically.Expected result is got,which provides experience for similar projects in the future. |
