bascule

When it was built, Tower Bridge was the largest and most sophisticated bascule bridge ever built （"bascule" comes from the French for "see-saw"）.

塔桥竣工时，是当时最大最精密的平衡活动结构（“平衡活动结构”一词法语的“”，下简称吊桥）。

Besides,the simulation model of steel deck pavement of the Tianjin Xiangluo Bay Bascule Bridge under vehicle load is established.

分析结果表明,不同力学响应为铺装层力学控制指标时,采用的仿真模型也不同;

The pumping unit adopts tower structure with great stability and easy to field installation. The pumping unit also adopts chorate bascule and easy to transport.

机架采用塔式结构，稳定性好，便于现场安装；大型机机架则采用活动收缩式结构，便于包装运输。
