Kugovaniswa kwemabhurudoza, Indian bulldozer ketani fekitori
Crawler dozer (inozivikanwawo se crawler dozer) yakagadzirwa zvakabudirira naBenjamin Holt, wekuAmerica, muna 1904. Yakagadzirwa nekuisa mabhurudhoza ekusimudza emaoko pamberi petirakita inokambaira.Panguva iyoyo, simba racho raiva injini yemhepo.Gare gare, madoza anokambaira aifambiswa nesimba regasi chaiwo uye injini yepeturu akagadzirwa.Iyo bulldozer blade yakagadziridzwa zvakare kubva pamanyorerwo ekusimudza kuenda kune waya yekusimudza tambo.Benjamin Holt aivawo mumwe wevakatanga Caterpillar Inc. muUnited States.Muna 1925, Holt Manufacturing Company neC 50. Best Bulldozer Company yakabatana kuita Caterpillar Bulldozer Company, ikava kambani yekutanga pasi rose kugadzira mabulldozer, uye yakabudirira kuparura boka rekutanga remabhurudhoza makumi matanhatu ane injini dzedhiziri muna 1931. Nekufambira mberi kweruzivo rwemichina. , bulldoza yave inofambiswa neinjini dzedhiziri, uye blade yebulldozer uye scarifier zvese zvinosimudzwa nemasirinda ehydraulic.Pamusoro pemabhurudhoza erudzi rweanokambaira, kunewo mabhurudhoza erudzi rwematayi, ayo anenge makore gumi gare gare pane mabhurudhoza erudzi rwe crawler.Mabulldoza eCrawler ane mashandiro arinani ekunamira uye anogona kuita kukwezva kukuru, saka siyana uye huwandu hwezvigadzirwa zvavo kumba nekune dzimwe nyika zvakatonyanya kupfuura izvo zvematayi mabulldoza.Pasi rose, Caterpillar ndiyo hombe inyanzvi yekugadzira michina yekugadzira kambani munyika.Mabulldozer ayo egonye anosanganisira makuru, epakati uye madiki akatevedzana D3-D11, hombe D11 RCD, uye flywheel simba reinjini yedhiziri rinosvika 634kw;Komatsu, kambani yekuJapan, iri pachinzvimbo chechipiri.Muna 1947, yakatanga kuunza uye kugadzira D50 crawler bulldozers.Kune gumi nenhatu dzakatevedzana dzeanokambaira mabulldozer, kubva kuD21-D575, diki iD21, simba reflywheel reinjini yedhiziri i29.5kw, hombe iD575A-3SD, uye simba rekubhururuka reinjini yedhiziri i858kw.Ndiro zvakare bhurudhoza rakakura kwazvo pasi rose parizvino;Imwe yakasarudzika mabulldozer inogadzira Liebheer Boka rekuGermany.Mabulldozers ayo ese anofambiswa ne hydrostatic pressure.Mushure memakore anopfuura gumi ekutsvakurudza uye kubudirira, teknolojia iyi yakaunza prototype muna 1972. Muna 1974, yakatanga kubereka PR721-PR731 uye PR741 hydrostatic driven crawler bulldozers.Nekuda kwekuganhurwa kwe hydraulic components, simba rayo guru rinongova 295Kw, uye muenzaniso wayo ndeye PR751 migodhi.
Vagadziri vatatu vari pamusoro apa vanomirira nhanho yepamusoro-soro yemabhurudhoza anokambaira pasi rose nhasi.Vamwe vagadziri vekunze vanokambaira mabulldozer, vakaita saJohn Deere, Nyaya, New Holland naDreista, vanewo tekinoroji yepamusoro yekugadzira.Indian bulldozer chain fekitori
Kugadzirwa kwemabulldozer muChina kwakatanga mushure mekuvambwa kweNew China.Pakutanga, bulldozer yakaiswa patarakita yekurima.Nekuvandudzwa kwehupfumi hwenyika, kudiwa kwemabhurudoza epakati nehombe mumigodhi mikuru, kuchengetedza mvura, zviteshi zvemagetsi nemadhipatimendi ezvekutakurwa kuri kuwedzera.Kunyangwe indasitiri yekugadzira yemabhurudoza epakati nehombe muChina yafambira mberi zvikuru, haichakwanisi kuzadzisa zvinodiwa zvekusimudzira hupfumi hwenyika.Naizvozvo, kubvira 1979, China yakatevedzana yakaunza tekinoroji yekugadzira, maratidziro ekuita, tekinoroji zviyero uye masisitimu emidziyo yeanokambaira mabulldozer kubva kuKomatsu Kambani yekuJapan neCaterpillar Company yekuUnited States.Mushure mekugaya uye kunyura, uye matekinoroji akakosha akabatwa, pateni inotongwa neKomatsu tekinoroji zvigadzirwa mu1980s uye 1990s yakaumbwa.Indian bulldozer chain fekitori
Kubva kuma1960s, kwave kune vangangoita vana vanogadzira muindasitiri yemabulldozer.Chikonzero ndechekuti izvo zvinodikanwa zvekugadzirisa zvezvigadzirwa zvebulldozer zvakakwirira, kuoma kwakakura, uye kugadzirwa kwakawanda kunoda mari yakakura.Naizvozvo, mabhizinesi akajairwa haadi kubatanidzwa nyore nyore.Nekudaro, nekuvandudzwa kwemusika, kubvira "Eighth Five Year Plan", mamwe makambani makuru uye epakati nepakati muChina akatanga kushanda panguva imwe chete mabulldozer maererano nesimba ravo, seInner Mongolia No.1 Machinery Factory, Xuzhou. Loader Factory, nezvimwe, uye yakawedzera iyo bulldozer indasitiri timu.Panguva imwecheteyo, mabhizinesi mashoma akatanga kuderera nekuda kwekusafambiswa zvakanaka uye kudikanwa kwekuenderana nekusimudzira musika, uye vamwe vakabuda muindasitiri iyi.Parizvino, vagadziri vepamba mabhurudhoza vanonyanya kusanganisira Shantui Construction Machinery Co., Ltd., Hebei Xuanhua Construction Machinery Co., Ltd., Shanghai Pengpu Machinery Factory Co., Ltd., Tianjin Construction Machinery Factory, Shaanxi Xinhuang Industrial Machinery Co., Ltd. ., Yituo Construction Machinery Co., Ltd., etc. Pamusoro pekugadzirwa kwemabulldozer, makambani ari pamusoro akatangawo kuita kugadzirwa kwezvimwe zvigadzirwa zvemichina yekuvaka, seShantui, iyo inoburitsawo ma roller emigwagwa, magiredhi, macherwa. , maloaders, forklifts, etc. Indian bulldozer chain factory
