摘要
以四台 TQ60/80塔机的塔身为行走主体,其上安装六四式军用钢梁,使之成为一台可拆卸型的高架龙门吊机,解决了太型桥梁构件吊装的难题。
With four TQ60/80 tower crane pillars being refitted into travelling portal frames and with steel beams being erected on their top,a detachable portal crane comes into being.By doing so,difficulties are solved for hoisting the components used in large-scale bridge.
