Crawler dozer (izwi kandi nka crawler dozer) yatunganyijwe neza na Benjamin Holt, Umunyamerika, mu 1904. Yashinzwe no gushyiramo bulldozer itwara intoki imbere ya traktori itwara amaguru. Icyo gihe, ingufu zari moteri y'umwuka. Nyuma, crawler dozers zitwarwa n'ingufu za gaze karemano na moteri ya lisansi zakozwe. Ibyuma bya bulldozer nabyo byakozwe kuva ku guterura intoki kugeza ku guterura imigozi y'insinga. Benjamin Holt na we yari umwe mu bashinze Caterpillar Inc. muri Leta Zunze Ubumwe za Amerika. Mu 1925, Holt Manufacturing Company na C 50. Best Bulldozer Company byahuje birema Caterpillar Bulldozer Company, biba iya mbere ku isi mu gukora ibikoresho bya bulldozer, kandi byatangije neza itsinda rya mbere rya bulldozers 60 zifite moteri za mazutu mu 1931. Bitewe n'iterambere rikomeje mu ikoranabuhanga, bulldozer yakoreshejwe na moteri za mazutu, kandi icyuma cya bulldozer n'icyuma gishyushya byose bizamurwa na silindiri za hydraulic. Uretse amapine y’ubwoko bwa crawler, hari n’amapine y’ubwoko bwa bulldozer, amaze imyaka igera ku icumi arusha amapine y’ubwoko bwa crawler. Amapine y’ubwoko bwa Crawler afite ubushobozi bwo gufata neza kandi ashobora gukurura cyane, bityo ubwinshi n’ingano by’ibicuruzwa byayo mu gihugu no mu mahanga ni byinshi cyane kurusha amapine y’ubwoko bwa bulldozer. Ku rwego mpuzamahanga, Caterpillar ni ikigo kinini cyane gikora imashini z’ubuhanga ku isi. Amapine y’ubwoko bwa caterpillar arimo D3-D11 nini, iciriritse n’into, D11 RCD nini cyane, kandi imbaraga za moteri ya mazutu zigera kuri 634kw; Komatsu, ikigo cyo mu Buyapani, cyaje ku mwanya wa kabiri. Mu 1947, yatangiye gutangiza no gukora amapine y’ubwoko bwa D50. Hari urukurikirane 13 rwa crawler bulldozers, kuva kuri D21-D575, ntoya ni D21, ingufu za moteri ya mazutu ziguruka ni 29.5kw, nini ni D575A-3SD, kandi ingufu za moteri ya mazutu ziguruka ni 858kw. Ni na yo bulldozer nini cyane ku isi muri iki gihe; Undi muhanga udasanzwe wa bulldozer ni Liebheer Group yo mu Budage. Bulldozers zayo zose zitwarwa n'umuvuduko wa hydrostatic. Nyuma y'imyaka irenga icumi y'ubushakashatsi n'iterambere, iri koranabuhanga ryazanye prototype mu 1972. Mu 1974, yatangiye gukora bulldozers za PR721-PR731 na PR741 ziguruka ziguruka ziguruka ziguruka. Bitewe n'aho ibice bya hydraulic bigarukira, imbaraga zayo ntarengwa ni 295Kw gusa, kandi icyitegererezo cyayo ni ubucukuzi bwa PR751.

Abakora bulldozer batatu bavuzwe haruguru ni bo bafite urwego rwo hejuru rw'amabulldozer yo mu bwoko bwa crawler ku isi muri iki gihe. Abandi bakozi b'abanyamahanga bakora bulldozer yo mu bwoko bwa crawler, nka John Deere, Case, New Holland na Dreista, nabo bafite ikoranabuhanga ryo gukora.

Umusaruro w'amabati mu Bushinwa watangiye nyuma y'ishingwa rya New China. Mbere na mbere, amabati yashyizwe kuri traktori y'ubuhinzi. Bitewe n'iterambere ry'ubukungu bw'igihugu, icyifuzo cy'amabati manini n'amanini yo mu birombe binini, mu kubungabunga amazi, mu bigo by'amashanyarazi no mu mashami y'ubwikorezi kiriyongera. Nubwo inganda z'amabati manini n'amanini yo mu Bushinwa zateye imbere cyane, ntizigishobora guhaza ibyifuzo by'iterambere ry'ubukungu bw'igihugu. Kubwibyo, kuva mu 1979, Ubushinwa bwatangije ikoranabuhanga mu gutunganya, imiterere y'imikorere, amahame ya tekiniki n'uburyo bw'ibikoresho by'amabati yo mu Bushinwa yaturutse muri Komatsu Company yo mu Buyapani na Caterpillar Company yo muri Leta Zunze Ubumwe za Amerika. Nyuma yo gusya no kwinjiza, n'ikoranabuhanga ry'ingenzi ryarafashwe, icyerekezo cyiganjemo ibikoresho by'ikoranabuhanga bya Komatsu mu myaka ya 1980 na 1990 cyarashinzwe. Uruganda rw'amabati mu Buhinde rwashinzwe.

Kuva mu myaka ya 1960, habayeho inganda zigera kuri enye mu nganda zikora bulldozer mu gihugu. Impamvu ni uko ibisabwa mu gutunganya ibicuruzwa bya bulldozer ari byinshi, ingorane ni nyinshi, kandi umusaruro mwinshi usaba ishoramari rinini. Kubwibyo, ibigo bisanzwe ntibitinyuka kubyitabira byoroshye. Ariko, hamwe n'iterambere ry'isoko, kuva kuri "Gahunda y'imyaka itanu ya munani", ibigo bimwe na bimwe binini n'ibiciriritse mu Bushinwa byatangiye gukoresha bulldozer icyarimwe hakurikijwe imbaraga zabyo, nka Inner Mongolia No.1 Machinery Factory Factory, Xuzhou Loader Factory, nibindi, kandi byaguze itsinda ry'inganda zikora bulldozer. Muri icyo gihe, ibigo bike byatangiye kugabanuka bitewe n'imicungire mibi n'ibyifuzo byo kumenyera iterambere ry'isoko, kandi bimwe byaravuye mu nganda. Kugeza ubu, inganda zikora amabati yo mu gihugu zirimo cyane cyane Shantui Construction Machinery Co., Ltd., Hebei Xuanhua Construction Machinery Co., Ltd., Shanghai Pengpu Machinery Factory Co., Ltd., Tianjin Construction Machinery Factory Factory, Shaanxi Xinhuang Industrial Machinery Co., Ltd., Yituo Construction Machinery Co., Ltd., n'izindi. Uretse gukora amabati yo mu bwoko bwa bulldozer, izi sosiyete zavuzwe haruguru zatangiye no gukora izindi mashini z'ubwubatsi, nka Shantui, inakora imashini zikora imihanda, imashini zipima, imashini zicukura, imashini zipakira imizigo, n'izindi. Uruganda rw'inganda zikora amabati yo mu Buhinde.
