Igabana rya buldozeri, uruganda rwumunyururu wa buldozer

Crawler dozer (izwi kandi ku izina rya crawler dozer) yatunganijwe neza na Benjamin Holt, Umunyamerika, mu 1904. Yashinzwe no gushyiramo buldozer yo guterura intoki imbere ya traktor yikurura.Muri kiriya gihe, ingufu zari moteri.Nyuma, imashini zikurura zikoreshwa ningufu za gaze na moteri ya lisansi.Icyuma cya bulldozer nacyo cyakozwe kuva mukuzamura intoki kugeza kuzamura umugozi.Benjamin Holt kandi yari umwe mu bashinze Caterpillar Inc. muri Amerika.Mu 1925, Uruganda rukora Holt na C 50. Isosiyete nziza ya Bulldozer yahujwe no gushinga uruganda rwa Caterpillar Bulldozer, ibaye uruganda rwa mbere ku isi rukora ibikoresho bya bulldozer, maze rutangiza icyiciro cya mbere cya buldozeri 60 hamwe na moteri ya mazutu mu 1931. Hamwe n’iterambere ry’ikoranabuhanga. , bulldozer yakoreshejwe na moteri ya mazutu, kandi buldozer icyuma na scarifier byose bizamurwa na silindiri hydraulic.Usibye ubwoko bwa bulldozers bwikurikiranya, hariho na buldozeri yo mu bwoko bwa tine, nyuma yimyaka icumi nyuma yubwoko bwa bulldozers.Crawler bulldozers ifite imikorere myiza yo gufatira hamwe kandi irashobora gukurura abantu benshi, kubwibyo ubwinshi nubwinshi bwibicuruzwa byabo mugihugu ndetse no mumahanga birarenze kure ibya buldozeri.Ku rwego mpuzamahanga, Caterpillar nisosiyete nini ikora imashini zikoresha imashini nini ku isi.Caterpillar bulldozers zirimo urukurikirane runini, ruciriritse na ruto D3-D11, runini D11 RCD, kandi ingufu za moteri ya moteri ya mazutu igera kuri 634kw;Isosiyete y'Abayapani Komatsu, yaje ku mwanya wa kabiri.Mu 1947, yatangiye kumenyekanisha no gukora D50 crawler bulldozers.Hano hari serie 13 za crawler bulldozers, kuva kuri D21-D575, umuto ni D21, ingufu za flawheel ya moteri ya mazutu ni 29.5kw, nini nini ni D575A-3SD, naho ingufu za moteri ya moteri ya mazutu ni 858kw.Nibindi binini binini ku isi muri iki gihe;Undi muntu udasanzwe ukora bulldozer ni Liebheer Group yo mubudage.Bulldozers yayo yose itwarwa numuvuduko wa hydrostatike.Nyuma yimyaka irenga icumi yubushakashatsi niterambere, ubwo buryo bwikoranabuhanga bwatangije prototype mumwaka wa 1972. Mu 1974, bwatangiye gukora cyane PR721-PR731 na PR741 hydrostatike itwara crawler bulldozers.Bitewe no kugabanya ibice bigize hydraulic, ingufu zayo ntarengwa ni 295Kw gusa, naho icyitegererezo cyayo ni PR751 ubucukuzi.

Ibicuruzwa bitatu bya bulldozer byavuzwe haruguru byerekana urwego rwo hejuru rwa crawler bulldozers kwisi kwisi.Abandi banyamahanga bakora ibicuruzwa bya crawler bulldozers, nka John Deere, Case, New Holland na Dreista, nabo bafite urwego rwo hejuru rwikoranabuhanga.Uruganda rwa bulldozer
Umusaruro wa buldozer mu Bushinwa watangiye nyuma y'Ubushinwa bushya.Ubwa mbere, buldozeri yashyizwe kuri traktor yubuhinzi.Iterambere ry’ubukungu bw’igihugu, isabwa rya buldozeri yo hagati nini nini nini mu birombe binini, kubungabunga amazi, sitasiyo y’amashanyarazi n’ishami rishinzwe gutwara abantu biriyongera.Nubwo inganda zikora inganda nini nini nini zikurura bulldozers mu Bushinwa zateye imbere cyane, ntizishobora kongera ibikenewe mu iterambere ry’ubukungu bw’igihugu.Kubera iyo mpamvu, guhera mu 1979, Ubushinwa bwagiye bukurikirana uburyo bwo gukora ibicuruzwa, ibisobanuro bitunganijwe, ibipimo bya tekiniki na sisitemu y’ibikoresho bya crawler bulldozers yo mu Isosiyete ya Komatsu yo mu Buyapani na Sosiyete Caterpillar yo muri Amerika.Nyuma yo gusya no kwinjizwa, hamwe nikoranabuhanga ryingenzi byakemuwe, hashyizweho uburyo bwiganjemo ibicuruzwa byikoranabuhanga bya Komatsu mu myaka ya za 1980 na 1990.Uruganda rwa bulldozer

Kuva mu myaka ya za 1960, habaye inganda zigera kuri enye mu nganda za buldozer.Impamvu nuko ibisabwa gutunganya ibicuruzwa bya bulldozer ari byinshi, ingorane nini, kandi umusaruro mwinshi bisaba ishoramari rinini.Kubwibyo, ibigo bisanzwe ntibitinyuka kubigiramo uruhare byoroshye.Icyakora, hamwe n’iterambere ry’isoko, kuva “Gahunda y’imyaka umunani n’umunani”, ibigo bimwe na bimwe binini n’ibiciriritse mu Bushinwa byatangiye gukora icyarimwe buldozeri ukurikije imbaraga zabo bwite, nk’uruganda rw’imashini rw’imbere muri Mongoliya, Xuzhou Uruganda rwabatwara, nibindi, kandi rwaguye itsinda ryinganda za bulldozer.Muri icyo gihe, umubare muto w’ibigo byatangiye kumanuka kubera imiyoborere mibi no gukenera guhuza iterambere ry’isoko, ndetse bamwe bava mu nganda.Kugeza ubu, uruganda rukora buldozer rurimo cyane cyane Shantui Construction Machinery Co., Ltd., Hebei Xuanhua Construction Machinery Co., Ltd., Shanghai Pengpu Machinery Factory Co., Ltd. ., Yituo Construction Machinery Co., Ltd., nibindi , abatwara ibintu, forklifts, nibindi
