轨道梁上大吨位行走式塔式起重机安装技术

Study of the Techniques for Installing Large-tonnage Walking Tower Crane on Track Girder

近几年来大型钢结构在多层框架结构上得到广泛应用,由于受到施工场地、机械性能、施工成本等条件的限制,大型行走式塔式起重机在楼层施工上应用越来越广泛。由于各工程的结构特点各不相同,给塔式起重机行走带来的难度不一。对此,以杭州东站站房工程为例,介绍了塔式起重机的选型、安装及拆除技术。

In recent years, large-scale steel structure has been utilized extensively on multi-layer frame structure, and large-scale walking tower crane has been increasingly applied in construction of floor. Structural differences among different projects bring about different difficulties in the walk of tower crane. This paper takes the newly-buih Hangzhou East Railway Station as an example in order to provide a reference for similar projects.
