I-double girder goliath crane ivamise ukusetshenziselwa ukuvula amashedi noma eduze komzila wezitimela ukwenza imisebenzi evamile yokuhambisa nokuphakamisa izinto, njengamayadi okulayisha noma izinsimbi, njll. I-crane ephezulu ayikwazi ukwenza. Amandla okuphakamisa ama-double girder cranes angaba ngamakhulu amathani, ngakho-ke nawo awuhlobo olusindayo lwe-gantry crane.
I-double girder i-Goliath Gantry Crane inezinhlelo zokusebenza ezimbonini ezahlukene zokuphakamisa imithwalo esindayo engakwazi ukuphathwa ngezinye izinto ezihambayo. I-Goliath Crane (eyaziwa nangokuthi i-Gantry Crane) iwuhlobo lwe-air crane enokusetha okukodwa noma okukabili okusekelwe imilenze ngayinye ehamba ngamasondo noma amasistimu kaloliwe, noma kumathrekhi. I-double girder Goliath Gantry Crane isetshenziselwa ukuphatha izinhlobo ezidlulele zemithwalo esindayo etholakala ezinhlelweni eziningi zezimboni. Ama-cranes e-double girder goliath nawo ahlolwa ngabasebenzi abanekhono lokulawula ikhwalithi ngokuya ngamapharamitha athile womkhakha.
I-SEVENCRANE yakha i-double girder goliath crane ngokuya ngemininingwane edingwa ngamakhasimende. I-SEVENCRANE yokuphakamisa igiya inamandla okuphakamisa ajwayelekile afinyelela kumathani angama-600; ngale kwalokhu, sinikeza i-winch gantry crane enamandla kakhulu yokuvula. I-double girder gantry inesicelo esiyingqayizivele ekuthuthweni kwemikhumbi, kwezezimoto, ekukhiqizeni umshini osindayo, njll. I-Goliath gantry crane eklanywe ngokukhethekile inezinhlelo zokusebenza futhi kumayadi ensimbi, ukukhiqizwa kwamashubhu, kanye nezimboni zemabula & negwala. I-double girder gantry crane yakhelwe kahle ukuphatha imithwalo esindayo, futhi inikeza izindlela ezihlelekile zokuphakamisa noma ukuhambisa imithwalo esindayo ngaphesheya kwegceke, noma ngokujwayelekile ukukhiqiza/ukugcina impahla noma izitolo zokukhiqiza.
Nakuba ngokuvamile esetshenziswa emasimini angaphandle, ama-double girder gantry cranes angasetshenziswa nangaphakathi kwezimboni.Lapho i-double-girder gantry crane isetshenziswa endlini, ikhasimende alidingi ukufaka izakhiwo zensimbi ezengeziwe ukuze lisize umsebenzi walo.
