摘　　要：重庆大佛寺长江大桥为主跨 4 50m的双塔双索面预应力混凝土斜拉桥 ,其主梁现浇节段规模大 ,重量重 ,挂篮预抛及退索索力大 ,主体结构设计与监控对挂篮自重与刚度要求高。介绍该桥采用桁架式轻型牵索挂篮的结构设计与试验结果。该挂篮具有重量轻、刚度大 ,综合技术指标高的特点 ,对同类型的斜拉桥施工具有广泛的应用价值。The cast-in-place segments of main girders of Dafosi Changjiang River Bridge in Chongqing are broad in scale and heavy in weight, suspended wagon pre-ejection and cable retreation force and large, designing of main structure and supervisory control need high rigidity to suspended wagon, so it has a certain degree of difficulty in design of suspended wagon. This paper introduces the designing and test of suspended wagon, giving the design concept and method for solving the technical difficulty.
