Ukubuka Konke Okuphelele Kwe-Bridge Girder Launching Crane

Ukwakhiwa kwebhuloho kuwumsebenzi oyinkimbinkimbi noyinselele odinga ukusetshenziswa kwemishini nezinhlelo ezithuthukisiwe. Isici esibalulekile sokwakhiwa kwebhuloho ukufakwa kwamabhuloho, okuyisici esibalulekile esisekela idekhi yebhuloho. Ukuze kube lula ukwakhiwa kwamabhande ebhuloho ngendlela ephumelelayo nephephile, kusetshenziswa ama-crane okuphakamisa amabhande ebhuloho. Lawa ma-crane ayingxenye ebalulekile yezinhlelo zanamuhla zokwakha amabhuloho futhi adlala indima ebalulekile ekuphothulweni ngempumelelo kwamaphrojekthi ebhuloho.

Ama-crane okuphakamisa ama-bridge girder aklanyelwe ngokukhethekile ukuphatha ukuphakamisa nokubeka ama-bridge girder asindayo. Lawa ma-crane anezici ezikhethekile eziwenza akwazi ukwenza ukunyakaza okunembile nokulawulwayo okudingekayo ukuze kumiswe ama-beam. Ama-crane okuvula ama-beam avame ukufakwa ezisekelweni zesikhashana eduze noma eduze kwe-bridge deck, okuvumela ukuthi athuthwe ngobude be-bridge ngesikhathi sokwakhiwa.

Enye yezinzuzo eziyinhloko zokusebenzisa i-crane ephakamisa ibhuloho yikhono layo lokwenza lula inqubo yokwakha. Ngokusebenzisa le mishini ekhethekile, amaqembu okwakha angaphakamisa ama-brard girders ngempumelelo futhi awabeke endaweni yawo, okunciphisa isikhathi kanye nomsebenzi odingekayo ukufaka ama-brarders. Ngaphezu kwalokho, ukusebenzisa i-crane yokubeka i-launch beam kuthuthukisa ukuphepha ngokunciphisa izingozi ezihambisana nokuphathwa ngesandla kwemishayo esindayo.

Kunezinhlobo ezahlukene zama-crane okuphakamisa ama-bridge girder, ngalinye lenzelwe ukuhlangabezana nezidingo ezithile zephrojekthi. Amanye ama-crane aklanyelwe amabhuloho aqondile, kanti amanye ayakwazi ukuphatha imiklamo yamabhuloho agobile noma ahlukaniswe. Ukuguquguquka kwala ma-crane kuwenza afaneleke kumaphrojekthi ahlukahlukene okwakha amabhuloho.

Ngamafuphi, i-bridge girder crane iyingxenye ebalulekile yesistimu yesimanje yokwakha ibhuloho. Ikhono labo lokuphakamisa nokubeka imishayo esindayo ngokunemba nangokusebenza kahle libenza babe yingxenye ebalulekile ekuphothulweni ngempumelelo kwamaphrojekthi ebhuloho. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, kulindeleke ukuthi ama-girder crane athuthukile futhi angochwepheshe azothuthukiswa ukuze kuthuthukiswe amakhono emishini yokwakha ibhuloho.
