Le cantilever gantry crane luhlobo olusoloko lubonwa lukaloliwe oluxhonywe kwigantry crane esetyenziselwa ukuphatha imithwalo emikhulu ngaphandle, njengakwiiyadi zomthwalo, izibuko lolwandle. I-gantry crane enye okanye i-double beam gantry crane kufuneka ikhethwe ngokweemfuno ezithile kumthamo womthwalo kunye nezinye iimfuno ezikhethekileyo ezilungiselelwe. Xa ukuphakamisa imithwalo kungaphantsi kweetoni ezingama-50, ubude bungaphantsi kweemitha ezingama-35, akukho mfuneko ethile yesicelo, ukhetho lwe-gantry crane yohlobo olulodwa lwe-gantry lufanelekile. Ukuba iimfuno zentsimbi yomnyango zibanzi, isantya sokusebenza sikhawuleza, okanye inxalenye enzima kunye nenxalenye ende iphakanyisiwe rhoqo, ngoko kufuneka kukhethwe i-double beam gantry crane. I-cantilever gantry crane ifana nebhokisi, kunye ne-double girders i-slanted tracks, kunye nemilenze yohlulwe kwiintlobo ze-A kunye neeNdidi ze-U ngokweemfuno zokusetyenziswa.
I-double girder gantry crane iyasebenza kumthwalo oqhelekileyo, ukukhulula, ukuphakamisa, kunye nokuphatha imisebenzi kwiiyadi zangaphandle kunye neeyadi zikaloliwe. I-cantilever gantry crane iyakwazi ukuthwala imithwalo emikhulu, enzima kwiindawo ezingaphandle, ezifana namazibuko, iindawo zeenqanawa, iindawo zokugcina iimpahla, kunye neendawo zokwakha. I-cantilever gantry crane isetyenziswa kwiindlela zokuhamba ezibekwe phantsi, kwaye isetyenziswa kakhulu ekulayisheni nasekukhupheni imisebenzi kwiiyadi zokugcina zangaphandle, ii-piers, izityalo zamandla, izibuko kunye neeyadi zendlela kaloliwe, phakathi kwezinye. I-cantilever gantry crane isetyenziswe kwiindawo ezahlukeneyo zokusebenza ezivulekileyo zokuphatha imithwalo enzima okanye izinto eziphathekayo, ngokuqhelekileyo zifumaneka kwiindawo zokugcina iimpahla, kwiiyadi zikaloliwe, iiyadi zeebhokisi, iiyadi ezilahliweyo, kunye neeyadi zentsimbi.
Ngenxa yobume bayo, i-gantry crane yangaphandle sisiqwengana esibanzi sesixhobo somatshini esisetyenziswa rhoqo. Iigantries ziyafumaneka ngobuchule obufanayo kunye nespans to bridge cranes, kwaye zilungele usetyenziso lwangaphakathi kunye nangaphandle. Iigantries ziyafana neekhreyini zebhulorho, ngaphandle kokuba zisebenza kwiingoma ezingaphantsi komhlaba.
