塔吊施工方案 Tower Crane Installation Method Statement 一、概况 General 根据工程垂直吊装需要，在反应器框架南侧树立三台QTZ40塔吊。塔吊基础位于5、18、30轴。基础长4 m，宽4m，高1.4 m，均为C30钢筋砼。QTZ40塔式起重机为水平臂架、小车变幅、上回转自升式多用途塔机。所要安装的塔机起重臂架长43m，塔机有效使用高度为30m，根据实际情况需要安装12节标准节架，本机采取独立固定式安装。 3 QTZ40 tower cranes will be installed at the south side of reactor as per the requirement of vertical lifting for this project. The foundation of tower crane will be located on axis 5, 18 and 30. The foundation length is 4m, width 4m, height 1.4m, the foundation is made by C30 reinforcement cement. This crane is a kind of multipurpose rising slewing and self-elevating crane with the horizontal boom frame and trolley driving mechanism. Its loading boom is 43m long and the required effective operational height of the tower shall be about 30m with one piece of fixed mast/section and 12 pieces of add on sections with the isolated and firm tower crane foundation.
