摘　　要：以金仁桐高速公路大坝田特大桥(106m+200m+106m)悬浇刚构桥为依托,研究了一套无轨式三角形挂篮,介绍了该无轨式三角形挂篮的设计方案和操作步骤,对其进行受力分析,并与普通挂篮进行经济比选,最终解决了大跨悬浇梁腹板没有轨道锚固钢筋时的普通挂篮行走问题。This article is based on the Datbaian Extra Large Bridge(106m+200 m+106m)suspended cast rigid frame bridge on the Jinrentong Expressway,and studies a set of trackless triangular hanging baskets,introduces the design scheme and operation procedure of the trackless triangle hanging basket,carries on the force analysis,and makes the economic comparison with the ordinary hanging basket.Finally,the common hanging basket walking problem is solved when there is no track anchorage bar on the web oflong span hanging cast beam.
