Ukwakhiwa kweebhulorho ngumsebenzi onzima nonzima ofuna ukusetyenziswa kwezixhobo kunye neenkqubo eziphambili. Inkalo ebalulekileyo yokwakhiwa kweebhulorho kukufakelwa kweebhulorho, eziyinxalenye ebalulekileyo exhasa idekhi yebhulorho. Ukuze kube lula ukwakhiwa kweebhulorho ngendlela efanelekileyo nekhuselekileyo, kusetyenziswa iikhreyini zokuphakamisa iibhulorho. Ezi khreyini ziyinxalenye ebalulekileyo yeenkqubo zanamhlanje zokwakha iibhulorho kwaye zidlala indima ebalulekileyo ekugqityweni ngempumelelo kweeprojekthi zeebhulorho.
Iikhreyini zokuphakamisa iibhriji zenzelwe ngokukodwa ukuphatha ukuphakamisa nokubeka iibhrijini zebhrijini ezinzima. Ezi khreyini zixhotyiswe ngeempawu ezikhethekileyo ezizivumela ukuba zenze iintshukumo ezichanekileyo nezilawulwayo ezifunekayo ekumisweni kweebhini. Iikhreyini zebhini eziqalisiweyo zihlala zixhonywa kwizibonelelo zexeshana kwidekhi yebhriji okanye kufutshane nayo, nto leyo evumela ukuba zihanjiswe kubude bebhulorho ngexesha lokwakhiwa.
Enye yezona nzuzo ziphambili zokusebenzisa i-crane ephakamisa ibhulorho kukuba iyakwazi ukwenza lula inkqubo yokwakha. Ngokusebenzisa ezi zixhobo zikhethekileyo, amaqela okwakha anokuphakamisa ngokufanelekileyo ii-bridge girders aze azibeke endaweni yazo, nto leyo enciphisa ixesha kunye nomsebenzi ofunekayo ukufaka ii-girders. Ukongeza, ukusebenzisa i-crane ye-launch beam kuphucula ukhuseleko ngokunciphisa iingozi ezinxulumene nokuphathwa ngesandla kwee-beams ezinzima.
Kukho iintlobo ezahlukeneyo zeekhreyini zokuphakamisa iibhriji, nganye yenzelwe ukuhlangabezana neemfuno ezithile zeprojekthi. Ezinye iikhreyini zenzelwe iibhulorho ezithe tye, ngelixa ezinye zikwazi ukuphatha uyilo lweebhulorho ezigobileyo okanye ezihlukeneyo. Ukuguquguquka kwezi khreyini kuzenza zifaneleke kwiiprojekthi ezahlukeneyo zokwakha iibhulorho.
Ngamafutshane, i-bridge girder crane yinxalenye ebalulekileyo yenkqubo yokwakhiwa kwebhulorho yanamhlanje. Ukukwazi kwabo ukuphakamisa nokubeka imiqadi enzima ngokuchanekileyo nangokufanelekileyo kubenza babe yinxalenye ebalulekileyo ekugqityweni ngempumelelo kweeprojekthi zebhulorho. Njengoko ubuchwepheshe buqhubeka buhambela phambili, kulindeleke ukuba ii-bran girder crane eziphucukileyo nezingochwephesha ziya kuphuhliswa ukuze kuphuculwe ngakumbi amandla ezixhobo zokwakha ibhulorho.
