润扬大桥施工专用设备的开发研制

Developing and Research on Equipments Specialized in Construction of Runyang Suspension Bridge

跨缆吊机是悬索桥钢箱梁桥面单元提升安装的专用设备 ,主要有卷扬机提升式和液压提升式两种形式。通过对跨缆吊机工作条件和性能指标的分析 ,结合润扬大桥悬索桥钢箱梁吊装的实际情况以及对国外同类设备现状的分析研究 ,设计研制了适用范围广泛的全液压、模块式、集中控制的跨缆吊机。

The deck erection gantry is a specialized equipment for erection of suspension bridge deck segments,it has mainly two forms of winch type and hydraulic lifting type. By analysing service conditions and performance index of the gantry and investigating the same kind of deck erection gantries at home and abroad, a new-type of full hydraulic, modular, and concentrated controlled gantry with wide range of application is designed and developed in light of actual conditions of steel box girder erection in Runyang Suspension Bridge.
