Nhoroondo yebudiriro yemabhurudoza anokambaira
Tractor yerudzi rwetrack (inozivikanwawo se crawler dozer) yakabudirira kugadzirwa neAmerican Benjamin Holt muna 1904. Yakagadzirwa nekuisa bulldoza inosimudza munhu pamberi petirakita inokambaira.Simba panguva iyoyo raive injini yemhepo.Mushure meizvozvo, mabhurudoza emhando yeanokambaira aifambiswa nesimba regasi rechisikigo uye injini yepeturu akabudirira kugadzirwa zvakatevedzana, uye blade yebulldozer yakagadziridzwawo kubva pakusimudzwa kwemanyorero kuenda kusimudza tambo.
Benjamin Holt mumwe wevakatanga Caterpillar Inc. muUnited States.Muna 1925, 5Holt Manufacturing Company neCL Best Bulldozer Company zvakabatanidzwa kuita Caterpillar Bulldozer Company, ndokuva yekutanga pasi rose kugadzira midziyo yemabhurudoza.Muna 1931, boka rekutanga remabhurudhoza makumi matanhatu ane injini dzedhiziri rakabuditswa kubva pamutsetse wekugadzira.Nekuenderera mberi kwekufambira mberi kwetekinoroji, mabulldozer ese akafambiswa neinjini dzedhiziri, uye mabulldozer blades uye scarifiers zvese zvinosimudzwa nema hydraulic silinda.
Pamusoro pemabhurudhoza emhando yecrawler, mabhurudhoza anewo mabhurudhoza emhando yematai, ayo akazoonekwa papera makore anenge gumi kupfuura mabhurudhoza emhando yecrawler.Nekuda kwekuti mabhurudhoza anokambaira ane kuita kwakanaka kwekunamira uye anogona kuita kukwezva kukuru, siyana uye huwandu hwezvigadzirwa zvawo zvinodarika izvo zvematayi mabulldoza epamba nekune dzimwe nyika.
Pasi rose, Caterpillar ndiyo kambani hombe yekugadzira michina yekuvaka munyika.Mabulldozer ayo anokambaira anosanganisira 9 akatevedzana makuru, epakati uye madiki D3-D11, yakakura D11 RCD, uye injini yedhiziri flywheel simba rinosvika 634kw;Japan Kambani yeKomatsu iri pachinzvimbo chechipiri, uye yakatanga kuunza nekugadzira iyo D50 crawler bulldozer muna 1947.
Kune gumi nenhatu dzakatevedzana dzeanokambaira mabulldozer, kubva kuD21-D575, diki iri D21, injini yedhiziri flywheel simba i29.5kw, hombe iD575A-3SD, injini yedhiziri inobhururuka inosvika 858kw, iri zvakare hombe bulldozer mune world;Iyo hunhu inogadzira bulldozer iGerman Liebheer Boka (Liebheer), ine mabulldozer ese anofambiswa ne hydrostatic pressure.Mushure memakore anopfuura gumi ekutsvaga nekusimudzira, tekinoroji yakatanga prototype muna 1972, uye yakatanga kugadzirwa kweruzhinji muna 1974. PR721-PR731 uye PR741 hydrostatic drive crawler bulldozer, nekuda kwekuganhurirwa kwe hydraulic components, simba rayo guru rinongova 295Kw pa. ikozvino, modhi iri PR751 migodhi.
Vagadziri vatatu vari pamusoro apa vanomirira nhanho yepamusoro-soro yemabhurudhoza anokambaira pasi rose nhasi.Vamwe vagadziri vakati wandei vekune dzimwe nyika vanokambaira mabulldozer, John Deere, Nyaya, New Holland neDeresta, zvakare vane mwero wepamusoro wehunyanzvi hwekugadzira.
Kugadzirwa kwemabulldozer muChina kwakangotanga mushure mekuvambwa kweNew China.Pakutanga, mabhurudoza akaiswa pamatirakita ekurima.Nekuvandudzwa kwehupfumi hwenyika, kudiwa kwemabhurudoza epakati nepakati mumigodhi mikuru, kuchengetedza mvura, zviteshi zvemagetsi nemadhipatimendi ezvekutakurwa kuri kuwedzera.Kunyange zvazvo indasitiri yekugadzira mabhurudhoza ari pakati nepakati munyika yangu yakasimukira zvikuru, haisati yakwanisa kuita zvinodiwa mukusimudzira upfumi hwenyika.need.
Kuti izvi zviitike, kubvira 1979, nyika yangu yakaunza zvakatevedzana tekinoroji yekugadzira, maitiro ekuita, tekinoroji zviyero uye masisitimu emidziyo yeanokambaira mabulldozer kubva kuKomatsu Corporation yekuJapan neCaterpillar Corporation yekuUnited States.Iyo pateni inotongwa neKomatsu tekinoroji zvigadzirwa muma1980 nema1990s.
Kubva kuma1960 kusvika nhasi, nhamba yevagadziri vepamba yemabulldozer yakagadzikana paanenge 4. Chikonzero ndechekuti zvinodiwa zvekugadzirisa zvezvigadzirwa zvebulldozer zvakakwirira uye zvakaoma, uye kugadzirwa kwemazhinji kunoda mari yakawanda, saka mabhizinesi akajairika haatyi. kuisa tsoka mukati nyore.Zvisinei, nekuvandudzwa kwemusika, kutanga kubva ku "Eighth Five-Year Plan", mamwe mabhizimisi makuru uye epakati-kati akatanga kushanda mabulldozer panguva imwe chete maererano nesimba ravo pachavo, seInner Mongolia No. 1 Machinery Factory, Xuzhou Loader Factory, nezvimwewo, kuwedzera iyo bulldozer indasitiri timu.
Zvichakadaro, kunewo makambani mashoma akatanga kudzikira nekuda kwekusafambiswa zvakanaka kwezvinhu pamwe nezvinodiwa mukusimudzirwa kwemisika, uye mamwe akatobuda muindasitiri iyi.
Parizvino, iwo makuru ekugadzira epamba mabulldozer ndeaya:
Shantui Construction Machinery Co., Ltd., Hebei Xuanhua Construction Machinery Co., Ltd., Shanghai Pengpu Machinery Factory Co., Ltd., Tianjin Construction Machinery Factory, Shaanxi Xinhuang Machinery Co., Ltd., Yituo Construction Machinery Co., Ltd. ., nezvimwewo.
Pamusoro pekugadzira mabulldozer, makambani ataurwa pamusoro apa atangawo kutsika mukugadzira zvimwe zvigadzirwa zvemichina yekuvaka.Semuenzaniso, Shantui inogadzirawo ma roller emumugwagwa, magiredhi, madhiri, maloader, forklift, nezvimwe.
