2、标准建桥者可适用于几乎各种桥梁断面。当桥梁宽度，节段高度，翼板厚度发生变化时调整十分方便。 16 一般适用节块长度为3-5米，重量100-400吨。使用液压系统推进。横坡纵坡均可调整。 预制节块拼装挂蓝几乎可适用于未来项目的任何断面。 17FREE CANTILEVER BRIDGES WORLDS LONGEST SPANS No. 项目项目名称名称 Country 跨度跨度 Construction 设备设备提供商提供商 1 Stolmasundet bro Norway 301 1998 NRS 2 Raftsundet, Lofoten Norway 298 1998 NRS 3 Hu

The Bridgeb

5、uilder may be adapted to almost any cross-section and is easily adjustable during operation to variations in segment length, box height, web thickness, deck width and road alignment (gradient, curvature, super-elevations). The vertical deflection at the front of the Bridgebuilder is less than 25 mm

6、at maximum load. Formwork beams are designed for a maximum deflection of L/400 of their length. One Bridgebuilder may be assembled in one week. Rolling forward on rails, the reset time is short. 1920主轨主轨液压油缸液压油缸下拉油缸推进油缸主千斤顶主千斤顶21前后工作车前后工作车主轨主轨液压油缸液压油缸22前后工作车前后工作车主轨主轨液压油缸液压油缸主框架主框架23前后工作车前后工作车主轨主轨液压油
