由江苏省建筑科学研究院改进设计,江苏省邢江县第二建筑安装工程公司改制的意大利进口阿尔法A301(60tm)塔式起重机由原来举高76m增至123m。适应了深圳蛇口海晖大厦29层高层建筑之急需。92年年中海晖大厦封顶,按顶定工期完成施工。社会效益、经济效益显著。阿尔法塔机电力拖动系统较先进,有一定的耐用度,塔身铜结构材质基本属16Mn(化验结果报告)肢件截面选用较大。通盘考虑在不增大原主截面的前提下可增加塔机原举高的50％以上。经过省建科院实地现场踏勘、测绘等一系列调研活动获得数据,对铜结构系统校核验算,设计了标准节和附墙装置。邗江县第二建安公司,用二个月时间制
The improved Alpha A301 (60tm) tower crane imported from the second construction and installation engineering company of Xingjiang County, Jiangsu Province, was upgraded from the original height of 76m to 123m. Adapted to the urgent needs of the 29-story high-rise building in Shenzhen Shekou Haihui Building. In mid-1992, the Haihui Building was capped and construction was completed according to the top deadline. Social and economic benefits are significant. The Alpha Tower’s electric drive system is relatively advanced and has a certain degree of durability. The copper structure of the tower body is basically a 16Mn (test result report). Considering that it is possible to increase the original height of the tower crane by more than 50% without increasing the original cross section. After a series of research activities such as on-site field survey and surveying and mapping conducted by the Provincial Academy of Science and Technology, the data was obtained, and the standard section and wall-attached devices were designed for checking and checking the copper structural system.
