Ama-double girder gantry cranes ayinketho edumile emisebenzini yokuphakamisa umsebenzi osindayo edinga umthamo owengeziwe kanye nobude obude kune-single girder gantry cranes. Aklanywe futhi akhiqizwa ngezakhiwo zensimbi eziqinile futhi atholakala ezinhlobonhlobo zamakhono okuphakamisa, ukusuka kumathani angu-5 kuya kwangama-600.
Izici zama-double girder gantry cranes zihlanganisa:
1. Ukwakhiwa kwensimbi eqinile futhi ehlala njalo yokusebenza okuthembekile nokuhlala isikhathi eside.
2.Ubude obenziwa ngokwezifiso kanye ne-span ukuze kuhlangatshezwane nezidingo ezithile zokuphakamisa.
3. Izici zokuphepha ezithuthukisiwe, njengokuvikela ukugcwala kakhulu namabhuleki ezimo eziphuthumayo.
4.Ukusebenza okushelelayo nokuphumelelayo kokuphakamisa nokwehlisa okunomsindo omncane.
5. Kulula ukusebenzisa izilawuli zokunyakaza okunembe.
6. Izidingo zokulungisa eziphansi zokunciphisa isikhathi sokuphumula kanye nezindleko zokusebenza.
7. Itholakala ekucushweni okuhlukene, njenge-gantry egcwele noma encane, kuye ngohlelo oluthile.
Ama-cranes e-double girder gantry alungele uhla lwezimboni, okuhlanganisa ukuthutha, ukwakhiwa, nokukhiqiza, futhi afaneleka ukuphakamisa izimpahla ezisindayo nezinto zokwakha endaweni yangaphandle noma yasendlini.
Ama-double girder gantry cranes ama-cranes asindayo aklanyelwe ukuphakamisa nokuhambisa imithwalo esinda kakhulu. Ngokuvamile zinebanga elingaphezu kwama-35m futhi zingathwala imithwalo efika kumathani angama-600. Lawa ma-cranes avame ukusetshenziswa ezimbonini ezifana nokukhiqiza insimbi, ukwakha umkhumbi, kanye nokukhiqiza imishini esindayo, kanye nasezindaweni zemikhumbi nasemachwebeni ukuze kulayishwe futhi kuthululwe imikhumbi yezimpahla.
Ukwakhiwa kwama-double girder gantry cranes kukhethekile kakhulu, futhi ukukhiqizwa kwawo kudinga izinga eliphezulu lekhono nobungcweti. Amagida amabili axhunywe inqola ehamba ngobude be-span, okuvumela i-crane ukuthi ihambise umthwalo kuzo zombili izikhombisi-ndlela ezivundlile neziqondile. I-crane ingabuye ifakwe ngohlu lwezindlela zokuphakamisa, ezinjengama-electromagnets, amahhuku, kanye nokubamba, ukuze ivumelane nezinhlelo zokusebenza ezahlukene.
Kafushane, ama-double girder gantry cranes ayithuluzi elithembekile nelisebenzayo lokuhambisa imithwalo esindayo ezindaweni zezimboni, amachweba, kanye nezindawo zemikhumbi. Ngokuklama nokukhiqiza okufanele, lawa ma-cranes anganikeza iminyaka yesevisi ephumelelayo.
I-double girder gantry crane iklanyelwe ukuphakamisa nokuhambisa imithwalo esindayo ezindaweni ezihlukahlukene. Ukwakhiwa kanye nokukhiqizwa kwama-double girder gantry cranes kubandakanya izinqubo ezimbalwa eziqinisekisa ukwethembeka, ukuphepha, nokusebenza kahle kwazo.
Isinyathelo sokuqala sokuklama nokukhiqiza lawa ma-cranes sihlanganisa ukukhetha izinto ezifanele kanye nezingxenye. Insimbi esetshenziswa enqubweni yokukhiqiza kumele ibe namandla aphezulu kanye nokumelana nokugqwala okuhle kakhulu ukuze imelane nezimo zokusebenza ezinzima. Ubuchwepheshe be-welding obuthuthukisiwe bubuye busetshenziswe ukuxhuma izingxenye ezihlukahlukene ze-crane.
Isistimu yomklamo osizwa ngekhompuyutha isetshenziselwa ukudala imodeli enembile ye-3D ye-crane, esetshenziselwa ukuthuthukisa isakhiwo nokunciphisa isisindo se-crane ngenkathi igcina amandla ayo kanye nokuqina. Isistimu kagesi ye-gantry crane yakhelwe ukuqinisekisa ukusebenza kahle, ukwethembeka, nokuphepha.
Ukukhiqiza kwenzeka kuma-workshops akhethekile anezinhlelo eziqinile zokulawula ikhwalithi. Imikhiqizo yokugcina ihlolwa kanzima futhi ihlolwe ngaphambi kokulethwa ekhasimendeni. Le gantry crane iyisisetshenziswa esinokwethenjelwa kakhulu nesisebenza kahle esikwazi ukuphakamisa nokuhambisa imithwalo esindayo kalula.
