Izinsika zokugcina zibekwe kuzo zombili iziphetho zebhuloho. Isetshenziselwa ukudlulisa umthwalo ebhulohweni ekusekelweni kwebhuloho.
Kunezinhlobo ezimbili zokuthunyelwe kokuphela: owesilisa nowesifazane. Ngesikhathi sokufakwa, i-post end yowesifazane ifakwe ekugcineni kwesilisa se-truss, futhi i-post end post ifakwe ekugcineni kowesifazane we-truss. Izimbobo ezimbili eziyindilinga ohlangothini lwekholomu yokugcina zixhunywe kuma-chords angaphezulu naphansi we-truss, futhi imbobo ephezulu ye-elliptical ixhunywe ku-truss ye-second-tier; ingxenye engezansi yekholomu yokugcina inikezwe i-cantilever emfushane enezikhonkwane zokumisa kanye nensimbi ehambayo yokubeka nokulungisa i-Beam.
I-321-Type Bailey Bridge iwuhlobo lwesistimu yebhuloho engahlakazwa futhi yakhiwe ngokushesha. Yakhelwe ngokuya ngeBritish Compact-100 Bailey Bridge. Ibhuloho lonke lishiselwe ngensimbi eqinile eqinile. Ibhande lingamaphaneli ahlanganisiwe anesisindo esincane futhi amaphaneli axhunywe ngezikhonkwane zokuxhuma zamaphaneli. Ukuguqulwa phakathi kwezingxenye kulula futhi azisindi. Kulula ukuwahlanganisa noma ukuwaqaqa futhi uwathuthe. Ingase futhi ihlanganiswe ibe yizinhlobo ezahlukene zamabhuloho amaphaneli ngokuya ngobude bawo be-span kanye nemfuneko yokuhamba. Ngakho-ke, iye yasetshenziswa kabanzi njengamabhuloho ephaneli athuthuke kakhudlwana futhi aqinisekisiwe ezokuthutha eziphuthumayo.
