The invention relates to a novel cargo boom mounting mode of a boom tower crane and belongs to the technical field of boom tower cranes. After the boom tower crane completes mounting of a rotating platform, a counterweight, a tower top and an amplitude-change mechanism, the cargo boom mounting is carried out, and the cargo boom mounting steps are as follows: winding of an amplitude-change steel wire rope is carried out; a cargo boom and a lifting steel wire rope are mounted; and a cargo boom pull rod pulley block is mounted. The novel cargo boom mounting mode has the beneficial effects that the safety is high, the lifting steel wire rope is wound around the boom, the boom end is fixed by the rope end, the operations are completely completed on the ground, and the high-risk work such as thesituations that an auxiliary crane is adopted for dragging and mounting personnel need to walk back and forth at the high attitude is avoided; the mounting efficiency is high, the lifting steel wirerope winding process is completely completed on the ground, compared with the high-altitude work, by the adoption of the novel cargo boom mounting mode, the time is greatly saved, an auxiliary mechanism is utilized to mount the crane boom pull rod pulley block, the mounting is fast, and the cost is saved; and the humanization design is high, the work high above the ground is reduced greatly, the working time of the work high above the ground is greatly shortened, and the humanization is high.

    本发明涉及一种动臂塔机的新型起重臂安装方式,属于动臂塔机技术领域。动臂塔机完成回转平台、配重、塔顶及变幅机构安装之后进行起重臂安装,起重臂的安装步骤为:进行变幅钢丝绳的穿绕;安装起重臂和起升钢丝绳;安装起重臂拉杆滑轮组。本发明的有益效果是:1)安全性高,起升钢丝绳穿绕及绳端固定臂头过程,完全在地面完成,避免了在高度利用辅助起重机拖拽、安装人员来回走动等高危工作;2)安装效率高,起升钢丝绳穿绕过程完全在地面完成,相比高空作业,大大节约时间,利用辅助机构安装起重臂拉杆滑轮组,安装快速,节约成本;3)人性化设计高,大大减少了高空作业工作及工作时间,人性化高。
