I-double-beam gantry crane's girders kunye nezakhelo zizakhiwo ezidityanisiweyo ezingenamthungo, ezinomgangatho ophezulu wokuqina okuthe nkqo nokuthe tye. Indlela yokuhamba yetroli iqhutywa ngombane, i-double-beam gantry crane inokuxhotyiswa ngee-grapples kunye nezinye izixhobo zokuphakamisa izitya, ezifanelekileyo ukusetyenziswa okuhlukeneyo.
Ikhono lokuphakamisa i-double-beam gantry crane ingaba ngamakhulu eetoni, kwaye isetyenziswe ngokubanzi kwiindawo zokugcina izinto ezivulekileyo, iindawo zokugcina izinto eziphathekayo, izityalo zesamente, amashishini egranite, amashishini okwakha, amashishini eenjineli, iiyadi zendlela kaloliwe yokulayisha kunye nokukhulula. imithwalo. I-double beam gantry crane isetyenziswa ngokubanzi ekuphakamiseni umsebenzi onzima.
I-double beam gantry crane ilula kwaye iyaphatheka, isebenzisa imilenze ukubamba iibhulorho, izilingi, kunye nezinyusi. Kuyilo oluhamba phambili, i-double girder gantry cranes inokuvumela ukuphakama okuphezulu ngenxa yokuba i-hoist ixhonywe ngaphantsi komqadi. Abafuni izixhobo ezingaphezulu kwimiqadi yebhulorho kunye neenkqubo zendlela yeenqwelo-moya, ngoko ke imilenze yenkxaso yokwakha kufuneka ithathele ingqalelo eyongezelelweyo. I-double beam gantry crane ikwaqwalaselwa apho kukho isizathu sokungabandakanyi inkqubo yendlela yeenqwelo-moya exhonywe eluphahleni, kwaye isetyenziswa ngokwesiko kakhulu kwizicelo ezivulekileyo apho imiqadi kunye neentsika ezipheleleyo azinakufakwa, okanye zingasetyenziswa phantsi kwebhulorho ekhoyo-isithsaba. inkqubo.
Iikhreyini ezinebhanti eziphindwe kabini zifuna ukucaciswa okukhulu ngaphezulu kweekhreyini zomphakamo womgangatho wokuphakama, njengoko itroli yokunyusela ikhwela phezu kwemiqadi yebhulorho kwikhreyini. Isakhiwo esisisiseko se-double beam gantry crane kukuba imilenze kunye namavili ahamba kunye nobude benkqubo ye-beam yomhlaba, kunye namabhanti amabini agxininiswe emilenzeni, kwaye i-trolley ye-hoist imisa i-boom kwaye ihamba phezu kweebhanti.
