Kugoverwa kwemabulldozer, fekitori yeIndian bulldozer chain

Crawler dozer (inozivikanwawo secrawler dozer) yakagadzirwa zvinobudirira naBenjamin Holt, wekuAmerica, muna 1904. Yakaumbwa nekuisa bulldozer inosimudza nemaoko pamberi petractor inokwira. Panguva iyoyo, simba raive injini yesteam. Gare gare, macrawler dozer anofambiswa nesimba regasi rechisikigo uye injini yepeturu akagadzirwa. Bhara rebulldozer rakagadzirwawo kubva pakusimudza nemaoko kusvika pakusimudza tambo yewaya. Benjamin Holt aivewo mumwe wevakatanga Caterpillar Inc. muUnited States. Muna 1925, Holt Manufacturing Company neC 50. Best Bulldozer Company vakabatana kuti vagadzire Caterpillar Bulldozer Company, vachiva mugadziri wekutanga pasi rose wemidziyo yebulldozer, uye vakabudirira kutanga boka rekutanga remabulldozer makumi matanhatu ane mainjini edhiziri muna 1931. Nekufambira mberi kuri kuramba kuchiita tekinoroji, bulldozer yave ichishandiswa neinjini dzedhiziri, uye blade rebulldozer nescarifier zvese zvinosimudzwa nema hydraulic cylinders. Pamusoro pemabulldozer emhando yecrawler, kunewo mabulldozer emhando yematairi, ayo anotora makore angangoita gumi kupfuura mabulldozer emhando yecrawler. Mabulldozer ecrawler ane simba rekunamatira zviri nani uye anogona kubata zvakanyanya, saka mhando nehuwandu hwezvigadzirwa zvavo kumba nekune dzimwe nyika hwakawanda kupfuura hwemabulldozer ematairi. Pasi rese, Caterpillar ndiyo kambani huru yekugadzira michina yeinjiniya pasi rose. Mabulldozer ayo ecaterpillar anosanganisira makuru, epakati nediki D3-D11, D11 RCD hombe, uye simba re flywheel reinjini yedhiziri rinosvika 634kw; Komatsu, kambani yekuJapan, yaive yechipiri. Muna 1947, yakatanga kuunza nekugadzira mabulldozer eD50 crawler. Kune mabulldozer gumi nematatu akatevedzana, kubva paD21-D575, diki pane D21, simba reinjini yedhiziri rinotenderera 29.5kw, guru pane ose iD575A-3SD, uye simba reinjini yedhiziri rinotenderera 858kw. Ndiyo zvakare bulldozer hombe pasi rose pari zvino; Imwe kambani inogadzira bulldozer yakasiyana iLiebheer Group yeGermany. Mabulldozer ayo ese anofambiswa nekumanikidzwa kwemvura. Mushure memakore anopfuura gumi ekutsvaga nekugadzira, tekinoroji iyi yakaunza prototype muna 1972. Muna 1974, yakatanga kugadzira mabulldozer ePR721-PR731 nePR741 anofambiswa nemvura. Nekuda kwekuganhurirwa kwezvikamu zve hydraulic, simba rayo guru i295Kw chete, uye modhi yayo ndeyekuchera PR751.

Vagadziri vemabulldozer vatatu vari pamusoro apa vanomiririra huwandu hwepamusoro hwemabulldozer emagetsi anokambaira pasi rose nhasi. Vamwe vagadziri vekunze vemabulldozer emagetsi anokambaira, vakaita saJohn Deere, Case, New Holland naDreista, vanewo tekinoroji yepamusoro yekugadzira. Fekitori yeIndian bulldozer chain
Kugadzirwa kwemabulldozer muChina kwakatanga mushure mekutangwa kweNew China. Pakutanga, bulldozer yakaiswa patrakita yekurima. Nekukura kwehupfumi hwenyika, kudiwa kwemabulldozer epakati nepakati mumigodhi mikuru, kuchengetedza mvura, zviteshi zvemagetsi nemadhipatimendi ekufambisa kuri kuwedzera. Kunyangwe indasitiri yekugadzira mabulldozer epakati nepakati muChina yafambira mberi zvikuru, haichakwanisi kusangana nezvinodiwa nebudiriro yehupfumi hwenyika. Saka, kubvira 1979, China yakaunza tekinoroji yekugadzira, zvirevo zvemaitiro, zviyero zvehunyanzvi uye masisitimu ezvinhu zvemabulldozer emagetsi kubva kuKomatsu Company yeJapan neCaterpillar Company yeUnited States. Mushure mekugaya nekunyudza, uye matekinoroji akakosha agadziriswa, maitiro akatongwa nezvigadzirwa zvetekinoroji yeKomatsu muma1980 nema1990 akaumbwa. Fekitori yeIndian bulldozer chain yakaumbwa.

Kubva kuma1960, kwave nevagadziri vanosvika vana muindasitiri yemabulldozer emuno. Chikonzero ndechekuti zvinodiwa pakugadzirisa zvigadzirwa zvebulldozer zvakanyanya, kuoma kwacho kukuru, uye kugadzirwa kwakawanda kunoda mari yakawanda. Saka, makambani akajairika haashinga kubatanidzwa zviri nyore. Zvisinei, nekukura kwemusika, kubva pa "Eighth Five Year Plan", mamwe makambani makuru nepakati muChina akatanga kushandisa mabulldozer panguva imwe chete zvichienderana nesimba rawo, akadai seInner Mongolia No.1 Machinery Factory, Xuzhou Loader Factory, nezvimwewo, uye akawedzera timu yeindasitiri yemabulldozer. Panguva imwe chete, mabhizinesi mashoma akatanga kudzikira nekuda kwekusashanda zvakanaka uye kudiwa kwekugadzirisa musika, uye mamwe akasiya indasitiri. Parizvino, vagadziri vemabulldozer emumba vanosanganisira 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., nezvimwewo. Pamusoro pekugadzira mabulldozer, makambani ari pamusoro apa akatangawo kugadzira zvimwe zvigadzirwa zvemichina yekuvaka, zvakaita seShantui, iyo inogadzirawo maroller emigwagwa, magiredhi, ma excavator, ma loaders, forklifts, nezvimwewo.
