超大型桥式起重机安装技术研究

Extra Large Bridge Crane Installation Technology Research

某钢厂改造工程中钢水接收跨新增加一台200/63/20mA7铸造超大型冶金桥式起重机。由于场地狭小,精度要求高、安装难度大。针对该项目的施工难点和特殊工艺,打破常规,运用3D3S软件进行三维空间模拟实际吊装来确定吊装参数,创新地采用地面组装、分件抬吊、整体就位的安装技术,解决了超大型冶金桥式起重机安装技术难题,取得了良好的经济效益和社会效益。

Molten steel in a steel plant renovation project receives cross the new increases the one 200/63/20m A7 very large metallurgical bridge cast crane. As the small venues, high precision request, it is difficult to install. For the project construction difficulties and special techniques to break the routine, using 3D3S software three-dimensional space simulation of the actual lifting to determine the lifting parameters and innovative use of gronnd assembly, sub-lift crane, installation techniques of the overall place solves very large metallurgical bridge crane install technical problems, and achieves good economic and social benefits.
