<b>塔顶缆索吊机（V13新增）</b>：本桥跨越<b>无水山区大峡谷</b>，不设栈桥/水上钻孔平台；索塔与两岸桥台间以<b>塔顶缆索吊机</b>作为主吊运手段——两塔顶间张拉<b>主索（承重索）</b>（跨中垂度 f≈L/12≈18m），上设<b>起重小车（跑车）</b>沿索横移，吊钩下放至桥面/基坑吊装劲性骨架、钢筋笼、模板、索导管等；塔顶设<b>索鞍桁架</b>，主索两端经背索锚固于两岸<b>地锚</b>；⑨ <b>混凝土拌合站与泵站（V13新增）</b>：项目全桥混凝土采用<b>泵送施工工艺</b>，平均运距 <b>3km</b>——峡谷两岸各设<b>拌合站</b>（HZS120 双机搅拌楼 +
