Abstract
In 300,000 tons coal silo project of Shenhua Huanghua Port,the largest single-piece of steel structure is 380 tons in weight, which is lifted on top of the coal silo. Being restricted by site condition, two sets of 250t cranes are required for lifting steel structure on top of the silo by using double-crane lifting method. The construction sequence of portal frame at first and girder at second is adopted to guarantee the safety and economy of the hoisting construction, and complete the construction work smoothly, which will provide references for similar overhead hoisting of steel structure.关键词
