Imashini yo gukuraho Girder Gantry Crane

Ikiraro cyo gushyiraho imigozi (Bridge Girder) gikoreshwa ku mihanda minini, ku biraro bya gari ya moshi kugeza aho byubakwa ikiraro, inshingano yacyo nyamukuru ni ukuvuga ku gice cy’umuraba cyiza cyakozwe mbere kandi gitangwa ku nkuta nziza zakozwe mbere. Ibi bivuze ko cranes zifite ibisabwa byinshi bitandukanye kandi bifite umutekano mwinshi.
Imashini yo gukurura icyuma ikora ku kiraro yari igizwe ahanini n'icyuma gikurura icyuma, icyuma gikurura icyuma, amaguru y'imbere n'inyuma, icyuma gikurura ...
Imashini yo gushyiraho umugozi wo gushyiraho ikiraro ikoreshwa cyane mu kubaka imihanda minini na gari ya moshi. Iyi mashini ikoreshwa mu gushyiraho imigozi yo gushyiramo beto ku murongo wa gari ya moshi w’abagenzi wihuta cyane (250km, 350km). Iyi mashini ikwiriye imigozi ingana cyangwa imigozi itandukanye ishobora kuba metero 20, metero 24 na metero 32, 50. Igice cy'inyuma gifite imigozi ibiri. Kimwe mu bishyigikizo ni inkingi ya "C" ifite ikoranabuhanga rizunguruka n'iryagonga. Ikoranabuhanga rya "C" ry'inkingi ryazigamye umwanya wo kunyura mu ngendo kandi rituma umuntu ashobora kunyura mu tunnels akoresheje ikinyabiziga cyo kohereza umugozi.
