QT10 5 0 0t-m 45 0t港口起重机目前是国内起重吨位最大的港口机械。针对其强度要求高 ,大型构件制造及安装精度难以控制的设计难点 ,在设计过程中 ,不仅考虑了强度设计安全性、结构布置合理性 ,还考虑了加工工艺和施工安装 ,达到了安全、质量和节省成本的统一。整机使用至今已有 1年 ,各项性能指标均保持良好。 QT10 5 0 0t-m 45 0t port crane is currently the largest lifting tonnage port machinery. In the design process, not only the design safety of strength, structural arrangement rationality, but also the processing technology and construction and installation are taken into consideration in the design of the design difficulties of high strength and difficult to control the manufacturing and installation of large-scale components. The safety, quality And the unity of cost savings. The whole machine has been used for one year, all performance indicators are maintained.
