3顶板梁吊装方案 Roof girder hoisting plans
锅炉钢结构第八段立柱、横梁、拉条安装完毕后，根据大板梁吊装需要，部分杆件预留，经检验合格，才能进行板梁吊装。
锅炉顶板梁的吊装机械为FZQ2000/80t圆筒吊和CC1400/CC2500履带吊。FZQ2000/80t圆筒吊布置在#1、#2炉的两侧,每台炉有一台磨机缓装GBT50502-2009 建筑施工组织设计规范，CC2500/CC1400履带吊在2台炉中间机动布置，看情况缓装一台磨煤机，使CC2500/CC1400满足顶板梁吊装工况。。 FZQ2000/80t cylindrical crane and CC1400/CC2500 crawler crane are employed to hoist boiler roof plate girder. FZQ2000/80t cylindrical crane should be arranged in both sides of boiler #1and#2, each boiler should be arranged with one mill after later. , while CC1400 or CC2500 crawler crane should be arranged between the tow boilers ,one mill should be erected later if necessary so that CC2500/CC1400 can meet the requirement of roof plate girder hoisting.
板梁由专用平板车运输至炉右侧0m处，利用CC1400履带吊卸车或者两主吊同卸，其中J、K、 L三根板梁利用FZQ2000塔吊和CC2500/CC1400共同抬吊到安装位置。顺序依次为L、K、J，其余板梁由FZQ2000塔吊或CC2500/CC1400履带吊单独吊装。
Plate girder should handled to 0 m in the right side of boiler by special platform lorry, CC1400crawler cranes or main cranes should be used to unload. FZQ2000 tower crane and CC2500/CC1400 are used to lift J,K,L plate girder. Consequence is L,K,J, other plate girders should respectively be hoisted by FZQ2000 tower crane or CC2500/CC1400 crawler crane.
