Izi zimapangitsa kukhala chida chofunikira kwambiri pakusunga, kutsitsa, ndikutsitsa zotengera zokhazikika monga mayunitsi a 20ft, 40ft, ndi 45ft mwatsatanetsatane komanso mwaluso.

Kapangidwe ka gantry crane ya matayala nthawi zambiri imakhala ndi chimango chachitsulo, trolley yokhala ndi makina okweza, komanso chowulutsira chonyamulira chidebe. Trolley imayenda motsatira mtengo wa gantry, zomwe zimapangitsa kuti crane ikweze ndikuyika zotengera m'mizere ingapo ndi utali. Mitundu yapamwamba imatha kuyika zotengera mpaka zisanu ndi chimodzi kapena zisanu ndi ziwiri m'mwamba ndikudutsa mizere ingapo, kukulitsa kugwiritsa ntchito malo pabwalo. Ndi mphamvu zonyamulira kuyambira matani ambiri mpaka mazana a matani, crane ya RTG imatha kuthana ndi zolemetsa zamakono.

Chimodzi mwazabwino za crane ya gantry crane ndi kuthekera kwake. Zokhala ndi mitundu ingapo yowongolera-monga kuyenda molunjika, kuyenda kwa oblique, ndi 90-degree chiwongolero-crane imatha kuyenda mosavuta m'malo opapatiza, kuzungulira m'malo mwake, ndikusinthira kumayendedwe ovuta a pabwalo. Izi zimapangitsa kuti ikhale yoyenera kwambiri pamaterminal omwe ali ndi anthu ambiri komwe kusinthasintha ndi kulondola ndikofunikira.

Makina amakono a gantry crane amapangidwanso ndi mphamvu zamagetsi komanso chitetezo m'malingaliro. Ambiri amatengera makina oyendetsa magetsi kapena osakanizidwa okhala ndi ma frequency frequency control, ukadaulo wobwezeretsa mphamvu, komanso mawonekedwe anzeru. Chitetezo chimakulitsidwa kudzera pamakina odana ndi kugwedezeka, chitetezo chochulukirachulukira, ndi ntchito zodziyimira zokha, kuwonetsetsa kuti kasamalidwe ka ziwiya kotetezeka komanso koyenera.

Mwachidule, crane ya gantry ya rabara imaphatikiza mphamvu zonyamula katundu wolemetsa, kusinthasintha kwapamwamba, komanso kugwira ntchito mwanzeru kuti ipereke magwiridwe antchito apamwamba pamadoko ndi malo opangira zinthu. Kutha kwake kunyamula zotengera zazikulu bwino kumapangitsa kukhala maziko amalonda apadziko lonse lapansi komanso chida chofunikira pamayendedwe amakono apakati.
