| Abstract: | The paper introduces 20 000 t bridge crane and the twin-beam multiple-point hoisting mode.Through actual stress test during hoisting,it analyzes the stress distribution of extension plate and hoisted structure during hoisting and compares the result of stress test and that of finite element analysis,to provide several suggestions on heavy hoisting process design and hoisting strength analysis. |
