Double Girder Hejuru Craneni ikiraro cya kiraro gikwiranye no murugo cyangwa hanze ibikorwa byagenwe, kandi bikoreshwa cyane mugutwara no gutwara ibikoresho biremereye. Igishushanyo cyayo gikomeye nuburyo buhamye birakwiriye cyane cyane kubikorwa bikora bisaba guhagarara neza no guterana kuremereye.
Ugereranije n'umurongo umweikirarocrane,inshuro ebyiri girder hejuru ya craneufite imiterere ikomeye, imbaraga zikomeye zo kwikorera imitwaro, kandi ni byiza gukoresha. Kubwibyo, ubushobozi bwo guterura buringaniye, kandi irashobora gutwara ibintu biremereye kuva kuri toni 3 kugeza kuri toni 50. Umwanya wacyo urashobora guhindurwa ukurikije ibikenewe byihariye, kuva kuri metero 10.5 kugeza kuri metero 31.5, naho uburebure bwacyo bukava kuri metero 6 kugeza kuri metero 30, bushobora guhura nibikorwa bitandukanye. Kabiri ya girder hejuru ya crane igiciro giterwa nibintu nkubushobozi bwimitwaro, span, nibiranga ibicuruzwa, bigatuma ari ngombwa kubona igereranya ryuzuye.
Uburyo bwo gukora bwa kane burashobora gutoranywa ukurikije imiterere yihariye yikibanza, harimo ibikorwa byubutaka, ibikorwa bya kure, hamwe nigikorwa cya cab. Kubera ko ibyuma bibiri byiziritse hejuru yubusanzwe bifite umwanya munini, ubushobozi bunini bwo guterura, hamwe nuburebure bwo hejuru bwo hejuru, ibikorwa bya cab bikunda guhitamo kugirango umutekano wibikorwa bihamye.
Uwitekadouble girder eot craneirakwiriye cyane cyane aho ikorera isaba guhagarara neza hamwe no guteranya ibice binini. Ubushobozi bukomeye bwo kwikorera imitwaro hamwe nuburyo bugari bwa porogaramu bituma iba ibikoresho byingirakamaro kandi byingenzi mubikorwa bitandukanye. Haba mumahugurwa aremereye yimashini zikora, inganda zibyuma, cyangwa amahugurwa ya elegitoronike akenera ibikorwa byuzuye, birashobora gutanga imikorere myiza kandi yizewe.
Muguhitamo ibyuma bibiri bya eot crane, abayikoresha barashobora kuzamura cyane imikorere yimikorere mugihe umutekano wibikorwa. Uburyo bwinshi bwo gukora, ubushobozi bukomeye bwo kwikorera imitwaro hamwe nigishushanyo mbonera cyimiterere ituma ibikoresho bikunda guterurwa mubikorwa byinshi. Kuganirakabiri girder hejuru ya crane igiciroirashobora kuvamo kuzigama gukomeye, cyane cyane iyo uguze kubwinshi cyangwa kumishinga minini.
