摘　　要：天津市快速路南仓道铁东路立交主桥为双塔连体四索面预应力混凝土分幅斜拉桥,主梁标准段采用牵索挂篮施工,介绍在幅间净距小、梁下净空低的不利条件下牵索挂篮的设计。The main bridge of the Tiedong Road Interchange on the Nancang Avenue, the Rapid Road in Tianjin City is a prestressed concrete cable-stayed bridge with conjoined twin py lons, four cable planes and separated decks, and the standard segments of the main girders of the bridge were constructed by the guyed form travelers. This paper presents the design of the form travelers under the restrictive conditions that the spacing between the decks is small and the clearance below the decks is low.
