Underhung bhuloho ama-cranesUkukhetha okuhle kwezikhungo zefekthri kanye nezindawo zokugcina izimpahla ezifuna ukukhulula izithiyo zendawo phansi futhi kwandise ukuphepha nokukhiqiza. U-Underung Cranes (kwesinye isikhathi obizwa nge-underlung Bridge Cranes) awudingi ukusekela amakholomu esitezi. Lokhu kungenxa yokuthi ngokuvamile bagibela ama-flanges aphansi wemishayo ye-runway emiswe ophahleni lwesikhungo noma ophahleni.
Ngokwakheka ukufinyelela kokuphela, ngaphansiibhuloho Ama-Cranes enza ukusetshenziswa okuhle kwesikhala. Lokho wukuthi, bavumela ama-Cranes ukuba agibele eduze kwamaloli okugcina noma ama-rungaway aphela kunama-cranes ahamba phambili. Ukucushwa okumisiwe okumisiwe kuphinde kwandisa indlela eya ekugcineni kwebhuloho, noma ibanga lemishayo yebhuloho kusuka odongeni noma ekugcineni.
UAma-Nderhung Cranes anesikhundla esilinganiselwe sokuphakamisa ngoba imishayo imisiwe ophahleni lwesakhiwo. Ngaphambi kokukhetha ingaphansi kwa-buthaleka ibhulohouhlobo lwenyoni enkulu, kufanele uhlole amandla wesakhiwo sophahla lwesakhiwo. Ama-Beams Support angangezwa ukukhulisa umthamo womthwalo.
Iphakeme ku-I-Beams ngamandla, ukuqina, kanye nokungaguquguquki.
Impilo yethrekhi enwetshiwe iqhathaniswa nezinhlelo ze-I-Beam.
Ukuchazwa kohlelo kulula futhi kuyabiza.
Ujantshi oqondile uphumela ekufakweni okulula, okubonakalayo, okusebenzayo.
Amakhono okuhamba asebenza kahle aqeda izakhiwo ezixhaswayo ezibizayo.
Ukumiswa okuguquguqukayo kuhlinzekela impilo ende nokulungiswa okuncane.
Enye inzuzo enkulu yengaphansi kwa-isivimbo ngaphezulu kwe-cranesukuguquguquka kwabo ukuhambisa kuyo yonke indawo. Ngaphansiibhuloho Ama-Cranes ayakwazi ukusondela emaphethelweni ama-runways namabhuloho, anikezela ngegumbi elingaphezulu lezikhungo ezingatholwa yi-underhung cranes. I-Crane Hook nayo ilula ku-opharetha ukuthi isebenze ngoba incane futhi inikeza ukuguquguquka okwengeziwe ebhulohweni.
I-Sevecrane ingakusiza ukuthi uhlole zonke izinketho ezitholakalayo ze-crane bese ukhetha eyodwa evumelana kahle nesicelo sakho nesikhungo sakho. Bangakwazi futhi ukukweluleka ngezinhlelo zokulungisa ukugcina i-crane yakho isebenza ngokusebenza kahle kanye nokwethenjwa.
