Kapangidwe kake kakulu ndi kapangidwe ka chimango cha portal, komwe kamathandizira kuyika miyendo iwiri pansi pa mtanda waukulu ndikuyenda molunjika panjira yapansi. Ili ndi mawonekedwe ogwiritsidwa ntchito kwambiri pamalopo, magwiridwe antchito osiyanasiyana, kugwiritsidwa ntchito kwakukulu, komanso kufalikira kwamphamvu.
Pomanga, ma crane a gantry amagwiritsidwa ntchito makamaka ponyamula zinthu m'malo monga mayadi azinthu, mayadi opangira zitsulo, mayadi okonzeratu zinthu, ndi malo ogwirira ntchito zomanga siteshoni ya sitima yapansi panthaka. Pakuphwanyidwa kwa gantry crane, njira zotsatirazi zotetezera ziyenera kuganiziridwa.
1. Musanachotse ndi kusamutsakireni ya gantry, dongosolo lochotsera liyenera kutsimikiziridwa kutengera zida ndi malo omwe ali pamalowo, ndipo njira zaukadaulo zotetezera pakuchotsera ziyenera kupangidwa.
2. Malo ogwetsera ayenera kukhala osalala, msewu wolowera uyenera kukhala wopanda chopinga, ndipo pasakhale zopinga zomwe zili pamwambapa. Kukwaniritsa zofunikira za ma crane amalori, magalimoto onyamula katundu olowa ndi kutuluka pamalopo, komanso ntchito zonyamula katundu.
3. Mizere yochenjeza za chitetezo iyenera kuyikidwa mozungulira malo ogwetsera, ndipo zizindikiro zofunika zachitetezo ndi zizindikiro zochenjeza ziyenera kuyikidwa.
4. Ntchito yogwetsa isanayambe, zida ndi zipangizo zofunika kugwiritsidwa ntchito ziyenera kuyang'aniridwa, ndipo kugwetsako kuyenera kuchitika motsatira ndondomeko yogwetsa ndi kukhazikitsa.
5. Mukachotsa mtanda waukulu, zingwe zolumikizira chingwe ziyenera kukokedwa pa miyendo yothandizira yolimba komanso yosinthasintha. Kenako chotsani kulumikizana pakati pa miyendo yothandizira yolimba, miyendo yothandizira yosinthasintha, ndi mtanda waukulu.
6. Mukachotsa chingwe chachitsulo chonyamulira, chiyenera kupakidwa mafuta ndikukulungidwa mu ng'oma yamatabwa kuti chiyike.
7. Ikani chizindikiro pa zigawozo malinga ndi malo ake, monga mizere ndi mawu.
8. Zigawo zolekanitsa ziyeneranso kuchepetsedwa momwe zingathere kutengera momwe zinthu zilili pa mayendedwe.
