I-cranes ye-chere-to-chearner i-cranes, ekwabizwa ngokuba yi-cranes okanye i-crane bridges, ibalulekile kwi-terminal ekhethekileyo kwaye ikhutshiwe izixhobo kwi-teraayies kwaye zihlala zikwimiqathango yethutyana. Umsebenzi wabo ophambili kukulayisha kunye nokulayisha umthwalo kwinqanawa egcweleyo yezitya, ukuqinisekisa intshukumo ekhuselekileyo nenempumelelo yomthwalo ngaphakathi nangaphandle kwezibuko.
Yahluke kwi cranes ye-cranes, eyadi yeyadi, ekwabizwa ngokuba yi-qwayipha ye-ranes, yenzelwe ngokungqalileyo ukuba ilayishe kwaye ilayishe iiyadi zekhonteri. Olona hlobo luqhelekileyo lweyadi yeyadi yi-Gantry ye-Gantry enyukayo (i-RMG), umatshini owodwa osetyenziswa kwiiyadi zekhonteyina. I-RMGS isebenzisa amavili abalekayo kwiindlela zokuphakamisa kunye nezikhongozeli ze-stack kwaye zixhotywe zisasazo ezingama-20 ukuya kwengama-40 ukuya kwi-40-ezinyaweni zokuhlalisa indawo yokuhlala.
Xa kuthelekiswa nerabha yerabha ediniweyo (i-RGGS), i-RMGs inika izibonelelo ezininzi. Okokuqala, basebenzisa umbane ophambili njengoMthombo wamandla, ukuphelisa ukungcoliseka kwe-WIEL kwaye ube nobuhlobo obunobuhlobo ngakumbi. Okwesibini, banokunyusa amandla okuphakamisa kunye nesantya, ukuphucula ukulayisha kunye nokulayisha ukusebenza kakuhle. Ngapha koko, iTroel kaRMG ikwazi ukuhamba ngokukhawuleza ngelixa iphakamisa umthwalo, ukuphucula isantya sokusebenza kunye nokuguquguquka.
Ngamafutshane, amaqhinga aqaqambileyo kunye neyadi cranes badlala indima ebalulekileyo kwizixhobo kunye neeyadi. Ayikuphuculi nje ukufaka kunye nokulayisha ukusebenza ngokukuko kodwa kukuqinisekisa ukhuseleko kunye noqoqosho lokusebenza.
