摘要
以嘉绍大桥280 t变幅式桥面吊机特种起重设备为例,比选大型桥面特种吊机安装过程的"卧拼"和"立拼"两种高空散件拼装方案。选用了较优的"立拼"方案,介绍了其高空立式散件拼装的工艺和方法。实践证明该工艺安全、经济,快速可行且质量可靠,对类似拼装平台较小的桥面吊机拼装施工具有良好的借鉴性及参考价值。
Taking 280 t luffing erection crane for Jiashao Bridge,a kind of special lifting equipment,as an example,the paper compares two high-altitude parts assembly schemes-＂horizontal assembly＂and＂vertical assembly＂of large special erecting crane. The paper holds that the＂vertical assembly＂scheme is better and introduces the process and method of high-altitude vertical parts assembly. Practices show that the process promises reliable quality,and is very safe,economic,fast and feasible,which provides valuable reference for installing similar erection cranes with small assembly platforms.
