中联重科助力国内“跨海巨龙”主塔封顶

Recently, the first main pylon of the south navigable bridge of the Hangzhou Bay Sea-crossing Railway Bridge — the world’s longest sea-crossing railway bridge currently under construction — has been successfully topped out. Two Zoomlion L630-50 luffing jib tower cranes and two 4S2050 inclined construction hoists marked this milestone achievement and were fully involved in the construction of both main pylons of the south navigable bridge.

日前，世界在建最长跨海铁路大桥——杭州湾跨海铁路大桥南航道桥首座主塔成功封顶，来自中联重科的2台L630-50动臂塔机与2台4S2050倾斜式施工升降机现场“建证”，并全程参与了南航道桥两座主塔建设。
