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"）.

塔竣工时，是当时最大最精密的平衡构（“平衡构”一词源自法语的“秋千”，以下简称）。

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

析果表明,以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.

机架采用塔式构，稳定性好，便于现场安装；大型机机架则采用收缩式构，便于包装运输。
