3、3-5米，重量100-400噸。使用液壓系統(tǒng)推進(jìn)。橫坡縱坡均可調(diào)整。 預(yù)制節(jié)塊拼裝掛藍(lán)幾乎可適用于未來項(xiàng)目的任何斷面。 預(yù)制節(jié)塊拼裝用掛藍(lán)世界跨度最長(zhǎng)的混凝土懸臂梁橋 重量輕:The use of rectangular hollow sections in the main structural components and recoverable high strength bars in all stays and ties reduces the total steel weight to a minimum. 使用靈活:The Bridgebuilder may be adapted

4、 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). 撓度小:The vertical deflection at the front of the Bridgebuilder is less than 25 mm at maximum load.

5、Formwork beams are designed for a maximum deflection of L/400 of their length. 安裝快捷:One Bridgebuilder may be assembled in one week. Rolling forward on rails, the reset time is short. 建橋者掛藍(lán)主要特點(diǎn)：現(xiàn)澆混凝土建橋者主軌液壓油缸建橋者主要組成部分下拉油缸推進(jìn)油缸主千斤頂前后工作車主軌液壓油缸建橋者掛藍(lán)前后工作車主軌液壓油缸建橋者掛藍(lán)的主要組成部分NRS AS主框架前后工作車主軌液壓油缸建橋者的主要組成部分NRS
