Mu bigo by'ubushyuhe bwinshi n'imitwaro iremereye y'inganda z'ibyuma, ihanganye n'ibidukikije bikomeye by'ibikorwa by'ingufu nyinshi, imaze imyaka cumi n'ine ikora mu mutekano kandi neza, ibona imbaraga z'igihe kirekire z'ikirango cya "Kuangyuan" hamwe n'igihe. Iyi ni crane ya 280t four-girder foundry yateguwe na Henan Mine ku ruganda ruzwi cyane rw'ibyuma byo mu rugo.

"Iyi crane ya 280t four-girder foundry yatangiye gukora kuva mu 2011, kandi imaze imyaka 14. Ikora neza, mu buryo bwizewe kandi bunoze." Umuyobozi w'Akarere ka Gicumbi yitabiriye uyu muhango wagaragaje ubuhamya n'ishimwe rikomeye. Igishushanyo mbonera cy'Umujyi wa Kigali gitanga ubwishingizi bwuzuye bw'ibicuruzwa. Imyaka cumi n'ine y'imikorere itekanye kandi iboneye ntishobora gutandukanwa no gukurikirana ubuziranenge bukabije bw'ikirango cya "Kuanyuan". Kugenzura ubuziranenge bw'ibicuruzwa, kugenzura ubuziranenge bw'ibi Imashini yose ikoresha ibyuma bifite ingufu zo hejuru. Nyuma yo kugenzura neza ibikoresho, byemezwa ko buri gice cyicyuma cyujuje ibisabwa byo hejuru, gishyiraho urufatiro rukomeye rwo gukomeza gukomera kw'ibikoresho. Design optimization, stable quality Finite element analysis technology is used to precise optimize the four-girder structure of the crane. Binyuze mu igerageza ryisubiramo, imiterere ikorwa kugirango ishobore kwihanganira ingufu mu buryo buboneye kandi buboneye, ikongera cyane ubudahangarwa bw'ibikoresho mugihe cy'igihe kirekire cy'imitwaro iremereye. Uburyo bwo kugenzura umuvuduko mwinshi, bwizewe kandi bwizewe Iyi crane ikoresha sisitemu yo kugenzura PLC, ihuriweho n'igikoresho cyo kugenzura umuvuduko uhinduka, kugirango ugere ku bufatanye bunoze bwibice bitandukanye. Ibi ntibizamura imikorere y'akazi gusa, ahubwo binatuma habaho umutekano. Uburyo bwinshi bwo kubungabunga ibidukikije, imikorere ihamye Ifite ibikoresho byinshi byo kurinda umutekano, harimo kurinda umutwaro urengeje urugero, kurinda imipaka, guhagarara byihutirwa, nibindi, kugirango habeho umutekano wibikoresho n'abakozi, no guherekeza imyaka 14 yibikorwa byiza. Hitamo Henan Mine maze umenye ikirango cya "Kuanyuan". Hamwe n'icyizere n'ishimwe ry'abakiriya, tuzakomeza gutera imbere mu nzira y'inganda zo ku rwego rwo hejuru, dutanga ubufasha bwizewe, bwizewe kandi bworoshye gukoresha ibikoresho byo kuzamura hamwe na serivisi z'ubuzima bwuzuye ku nganda nyinshi.
