Kabirihejuru craneIrashobora gutwara imitwaro iremereye neza kandi neza. Kabiri girderhejuru crane ifite imikorere isumba iyindi, imiterere yoroheje, uburemere bworoshye, kwizerwa no gukora, kandi irashobora guhura nibikorwa bitandukanye. Irashobora kugabanya ishoramari muri rusange muruganda, kuzamura umusaruro, kugabanya ibiciro byo kubungabunga, no kuzigama ingufu zikoreshwa.
Ibiranga impuzu zibiri hejuru ya crane:
Imiterere yoroheje, kubungabunga byoroshye, gukoresha ingufu nke no kwihuta kwagutse.
Feri ikora iroroshye kandi igabanya neza kunyeganyega kwibintu biremereye, bigabanya imizigo, kandi bizamura imikorere.
Double girder hejuru ya crane ni fbyoroshye, bihuza binyuze muburyo butandukanye bwo kwishyiriraho.
Kubungabunga bike, urusaku ruke rwerekanwa na feri ya disiki hamwe na centrifugal mass.
Kwisi yose kwisi yabafatanyabikorwa bemewe, abakora crane nabubaka sisitemu.
Mbere yo gukoreshadouble girder Bridge crane:
Witondere kugenzura ibintu bitandukanye mbere yakazi. Menya neza ko abakwirakwiza buzuye kandi butuzuye. Nibait ni inenge, ntibizashoboka gukora nka kane.
Reba uko umugozi umeze. Menya neza umugoziBya iToni 10 hejuru ya crane ni umutekano kandi ntabwo irekuye cyangwa ivunitse. Niba uhambiriye ikintu hamwe nuruhande, ugomba kongeramo uburinzi hagati yikintu nu mugozi kugirango wirinde umugozi kumeneka.
Menya hagati yuburemere bwuburemere. Ibi birashobora kwirinda ibintu byo gukurura diagonal, kandi ibintu bidasanzwe byo guterura bisaba abakozi gukora.
Mugihe uteruye ibintu, ntukihute. Witondere gutegereza igihe kugirango ibicuruzwa bihagarare mbere yo gukomeza. Nta myanda yemerewe ku bintu biremereye, kandi nta muntu wemerewe kuyihagararaho. Igiheukoresheje toni 10hejuru to kuzamura ibicuruzwa, abakozi badafite aho bahurira ntibemerewe kunyura munsi yikintu.
Ingamba z'umutekano ku kazi zigomba kunozwa. Kurugero, abakozi bagomba kwambara ingofero yumutekano, abanyamwuga bagomba gutanga itegeko rimwe, kandi amashami atandukanye agomba guhuza akazi kayo. Iyo ikintu kizamuwe hasi, reba niba umugozi winsinga nibindi bikoresho bifite umutekano. Niba bidafite umutekano, hagarikakabiri girder hejuru ya cranekugenzura.
