Chiwombankhanga chachikulu cha rabara, chomwe chimadziwikanso kuti RTG crane, chimagwiritsidwa ntchito ponyamula katundu wolemera m'mayadi otengera katundu ndi malo ena onyamula katundu. Makoraniwa amayikidwa pa matayala a rabara, omwe amatha kusuntha pabwalo kuti apeze zotengera zosiyanasiyana.
Zina mwazinthu zama cranes akuluakulu a RTG ndi awa:
1. Mphamvu zonyamula katundu wolemera - makinawa amatha kukweza mpaka matani 100 kapena kuposerapo, kuwapanga kukhala abwino kunyamula ziwiya zazikulu ndi katundu wina wolemera.
2. Kuthamanga kwambiri - ndi mphamvu zamagetsi zamagetsi ndi makina a hydraulic, makina a RTG amatha kuyenda mofulumira komanso mogwira mtima kuzungulira bwalo.
3. Dongosolo lotsogola kwambiri - makina amakono a RTG ali ndi makina apamwamba kwambiri apakompyuta omwe amalola ogwiritsa ntchito kuwongolera bwino kayendedwe ka crane ndi kukweza kwake.
4. Mapangidwe osagwirizana ndi nyengo - Ma crane a RTG amapangidwa kuti athe kupirira mikhalidwe yovuta yakunja, kuphatikiza mphepo yamkuntho ndi mvula yamphamvu.
5. Zida zachitetezo - ma cranes awa ali ndi zida zambiri zotetezera, kuphatikiza chitetezo chochulukira, mabatani oyimitsa mwadzidzidzi, ndi machitidwe opewera kugunda.
Ponseponse, ma cranes akuluakulu a RTG ndi zida zofunika kwambiri potengera zotengera ndi zonyamula katundu, zomwe zimapatsa liwiro, mphamvu, komanso kulondola kofunikira kuti katundu aziyenda bwino pamadoko ndi ma terminals ena.
Large Tonnage Terminal Rubber Tyre Gantry Crane idapangidwa kuti inyamule ndi kunyamula zotengera zolemera pamadoko ndi ma terminals ena akulu. Kireni yamtunduwu ndiyothandiza makamaka pamadoko odzaza ndi zinthu komwe kuthamanga ndi kuchita bwino ndikofunikira pakusuntha zotengera kuchokera ku sitima kupita kumagalimoto kapena masitima apamtunda.
Large Tonnage Terminal Rubber Tire Gantry Crane ili ndi ntchito m'mafakitale angapo, kuphatikiza kutumiza, mayendedwe, ndi mayendedwe. Ndi chida chofunikira kwambiri popanga madoko azamalonda kuti azigwira bwino ntchito komanso ochita bwino, kuchepetsa nthawi yonyamula katundu, komanso kukonza njira zotumizira katundu.
Ponseponse, Large Tonnage Terminal Rubber Tire Gantry Crane ndi chida chofunikira kwambiri pakugwira ntchito bwino kwa ma terminals akulu, kuwapangitsa kuti athe kunyamula katundu wolemera, kuchepetsa ndalama, ndikuwonjezera magwiridwe antchito.
Njira yopangira Crane ya Large Tonnage Terminal Rubber Tire Gantry imaphatikizapo njira yovuta yopangira, uinjiniya ndi kusonkhanitsa zigawo zosiyanasiyana. Zigawo zazikulu za crane zimaphatikizapo kapangidwe kachitsulo, hydraulic system, magetsi, ndi control system.
Chitsulo chachitsulo chimapangidwa kuti chithandizire kulemera kwa katundu ndi kupirira zovuta za chilengedwe cha doko. Dongosolo la hydraulic limapereka mphamvu kuti crane ikweze ndikusuntha katundu, pomwe magetsi amapereka zowongolera pamayendedwe a hydraulic ndi odziyendetsa okha. Dongosolo lowongolera limapangidwa kuti lilole woyendetsa kuwongolera kayendedwe ka crane ndikuwonetsetsa kuti katunduyo ali ndi chitetezo. Msonkhano womaliza wa crane umachitikira pa doko pomwe idzagwiritsidwa ntchito, ndipo kuyesa mwamphamvu kumachitidwa kuti kuwonetsetse kuti ndi yotetezeka komanso yodalirika.
