Mosiyana ndi makola am'mwamba omwe amakhala ndi zomangira mlatho pamwamba pa mizati ya msewu wonyamukira ndege, chotchinga chapansi pa mlatho chimakhala ndi chomangira cha mlatho pansi pa mizati ya msewu wonyamukira ndege. Nazi zina ndi mawonekedwe a underhung bridge cranes:
Kusanjikiza: Ma cranes omwe ali pansi pa mlatho nthawi zambiri amakhala ndi chotchingira mlatho, magalimoto omalizira, msonkhano wokweza / trolley, ndi njira yothamangira ndege. Mlatho wa mlatho, womwe umanyamula chokwezera ndi trolley, umayikidwa m'munsi mwa matabwa a msewu.
Runway System: Njira yothamangira ndege imayikidwa panyumbayo ndipo imapereka njira yoti crane iyende mopingasa. Zimapangidwa ndi mizati yofanana ya msewu wonyamukira ndege yomwe imathandizira chomangira mlatho. Miyendo ya msewu wonyamukira ndege nthawi zambiri imayimitsidwa kuchokera panyumbayo pogwiritsa ntchito ma hanger kapena mabulaketi.
Bridge Girder: Mlatho wa mlatho ndi mtengo wopingasa womwe umadutsa pakati pa mizati ya msewu wonyamukira ndege. Imayenda motsatira njira yothamangitsira ndege pogwiritsa ntchito mawilo kapena zodzigudubuza zomwe zimayikidwa pamagalimoto omaliza. Mlatho wa mlatho umathandizira msonkhano wa hoist ndi trolley, womwe umayenda kutalika kwa mlatho wa mlatho.
Msonkhano wa Hoist ndi Trolley: Msonkhano wa hoist ndi trolley ndi udindo wokweza ndi kusuntha katundu. Zimapangidwa ndi chokweza chamagetsi kapena chamanja chomwe chimayikidwa pa trolley. Trolley imayendetsa pamphepete mwa mlatho, kulola chokweza kuti chiyike ndikunyamula katundu kudutsa malo ogwira ntchito.
Kusinthasintha: Ma cranes a Underhung bridge amapereka kusinthasintha pankhani ya kukhazikitsa ndi kugwiritsa ntchito. Nthawi zambiri amagwiritsidwa ntchito m'malo omwe mutuwo umakhala wocheperako kapena pomwe zida zomwe zilipo sizingathe kuthandizira kulemera kwa crane yapamwamba. Ma cranes omwe ali pansi amatha kukhazikitsidwa m'nyumba zatsopano kapena kusinthidwanso m'mapangidwe omwe alipo.
Zida Zopangira: Ma crane opangidwa ndi Underhung amagwiritsidwa ntchito pafupipafupi m'malo opangira kusuntha zida, zida, ndi zinthu zomalizidwa pamizere yolumikizira. Amathandizira kuyika bwino komanso moyenera makina olemera, zida, ndi zida panthawi yopanga.
Malo Osungiramo Zinthu ndi Malo Ogawira: Makorani omwe ali pansi panthaka amagwiritsidwa ntchito m'malo osungiramo katundu ndi malo ogawa kuti asamalire ndi kunyamula katundu, mapaleti, ndi makontena. Amathandizira kusuntha kwazinthu mkati mwa malo osungira, kukweza ndi kutsitsa magalimoto, ndikukonzekera zosungira.
Makampani Oyendetsa Magalimoto: Ma crane a Underhung amagwira ntchito yofunika kwambiri pamakampani amagalimoto. Amagwiritsidwa ntchito ngati kukweza ndi kuyika matupi agalimoto panthawi yolumikizana, kusuntha zida zamagalimoto olemera m'mizere yopangira, ndikukweza / kutsitsa zida zamagalimoto.
Makampani a Zamlengalenga: M'makampani opanga ndege, ma cranes omwe amang'ambika amagwiritsidwa ntchito posamalira ndi kusonkhanitsa zida zazikulu zandege, monga mapiko ndi ma fuselages. Amathandizira pakuyika bwino komanso kuyenda kwa magawo olemera komanso osalimbawa, ndikuwonetsetsa kuti njira zopangira zikuyenda bwino.
Kupanga Chitsulo: Ma cranes opangidwa ndi underhung amapezeka nthawi zambiri m'malo opangira zitsulo. Amagwiritsidwa ntchito ponyamula ndi kunyamula zitsulo zolemera, matabwa, ndi zigawo zina zamapangidwe. Ma cranes opangidwa ndi underhung amapereka mphamvu yonyamulira komanso kuyendetsa bwino ntchito zosiyanasiyana zopanga, kuphatikiza kuwotcherera, kudula, ndi kupanga ntchito.
Ma cranes omwe amapangidwa pamwamba pake amapeza ntchito m'mafakitale osiyanasiyana ndi malo omwe kugwiritsira ntchito bwino ndi kukweza zinthu kumafunika.Kusinthasintha kwawo, mphamvu zawo, ndi kusinthasintha zimawapangitsa kukhala chuma chamtengo wapatali m'mafakitale ambiri komwe kugwiritsira ntchito bwino ndi kukweza ntchito ndizofunikira.
