Subdivision ntawm bulldozers, Indian bulldozer saw Hoobkas
Crawler dozer (tseem hu ua crawler dozer) tau ua tiav los ntawm Benjamin Holt, tus neeg Asmeskas, hauv xyoo 1904. Nws tau tsim los ntawm kev txhim kho phau ntawv nqa lub tsheb nrau av pem hauv ntej ntawm lub tsheb laij teb crawler.Lub sijhawm ntawd, lub zog yog lub tshuab hluav taws xob.Tom qab ntawd, crawler dozers uas tau tsav los ntawm lub zog hluav taws xob thiab roj av tau tsim.Lub bulldozer hniav kuj tau tsim los ntawm phau ntawv nqa mus rau xaim hlua nqa.Benjamin Holt kuj yog ib tus tsim ntawm Caterpillar Inc. hauv Tebchaws Meskas.Xyoo 1925, Holt Manufacturing Company thiab C 50. Best Bulldozer Company tau koom ua ke los ua Caterpillar Bulldozer Company, dhau los ua lub ntiaj teb thawj cov khoom siv bulldozer, thiab ua tiav thawj batch ntawm 60 bulldozers nrog diesel xyaw hauv 1931. Nrog rau kev nce qib ntawm kev siv tshuab. , lub tsheb bulldozer tau siv los ntawm lub tshuab hluav taws xob, thiab lub tshuab bulldozer thiab scarifier yog txhua tus nqa los ntawm hydraulic thooj voos kheej kheej.Ntxiv nrog rau crawler hom bulldozers, tseem muaj cov log tsheb hom bulldozers, uas yog li kaum xyoo tom qab crawler hom bulldozers.Crawler bulldozers muaj kev ua tau zoo dua adhesion thiab tuaj yeem siv zog ntau dua, yog li ntau thiab ntau ntawm lawv cov khoom hauv tsev thiab txawv teb chaws muaj ntau dua li cov log tsheb bulldozers.Thoob ntiaj teb, Caterpillar yog lub tuam txhab engineering loj tshaj plaws hauv lub ntiaj teb.Nws caterpillar bulldozers muaj xws li loj, nruab nrab thiab me series D3-D11, qhov loj tshaj plaws D11 RCD, thiab lub flywheel zog ntawm diesel cav mus txog 634kw;Komatsu, ib lub tuam txhab Japanese, nyob qib thib ob.Xyoo 1947, nws pib qhia thiab tsim D50 crawler bulldozers.Muaj 13 series ntawm crawler bulldozers, xws li D21-D575, qhov tsawg tshaj plaws yog D21, lub zog flywheel ntawm diesel cav yog 29.5kw, qhov loj tshaj plaws yog D575A-3SD, thiab lub zog flywheel ntawm diesel cav yog 858kw.Nws tseem yog lub tsheb loj tshaj plaws hauv lub ntiaj teb tam sim no;Lwm qhov tshwj xeeb bulldozer chaw tsim tshuaj paus yog Liebheer Group ntawm lub teb chaws Yelemees.Nws cov bulldozers tag nrho yog tsav los ntawm hydrostatic siab.Tom qab ntau tshaj kaum xyoo ntawm kev tshawb fawb thiab kev tsim kho, cov cuab yeej no tau nthuav tawm cov qauv hauv xyoo 1972. Hauv xyoo 1974, nws tau pib tsim cov PR721-PR731 thiab PR741 hydrostatic driven crawler bulldozers.Vim muaj kev txwv ntawm cov khoom siv hydraulic, nws lub zog siab tshaj plaws tsuas yog 295Kw, thiab nws cov qauv yog PR751 tsuas.
Cov saum toj no peb lub bulldozer manufacturers sawv cev rau theem siab tshaj plaws ntawm crawler bulldozers nyob rau hauv lub ntiaj teb no niaj hnub no.Lwm cov tuam txhab txawv teb chaws ntawm crawler bulldozers, xws li John Deere, Case, New Holland thiab Dreista, kuj tseem muaj cov cuab yeej siv ntau lawm.Indian bulldozer saw Hoobkas
Kev tsim cov bulldozers hauv Suav teb tau pib tom qab kev tsim ntawm Tuam Tshoj Tshiab.Thaum xub thawj, lub bulldozer tau nruab rau ntawm lub tsheb laij teb ua liaj ua teb.Nrog rau txoj kev loj hlob ntawm kev lag luam hauv lub tebchaws, qhov kev thov rau nruab nrab thiab loj crawler bulldozers hauv cov mines loj, kev txuag dej, chaw nres tsheb fais fab thiab chaw thauj mus los tau nce.Txawm hais tias kev lag luam kev lag luam ntawm nruab nrab thiab loj crawler bulldozers hauv Suav teb tau ua tiav zoo, nws tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev lag luam hauv lub tebchaws.Yog li ntawd, txij li xyoo 1979, Tuam Tshoj tau ua tiav cov thev naus laus zis ntau lawm, cov txheej txheem kev qhia tshwj xeeb, cov qauv kev ua haujlwm thiab cov khoom siv ntawm cov tshuab bulldozers los ntawm Komatsu Company ntawm Nyiv thiab Caterpillar Company ntawm Tebchaws Meskas.Tom qab kev zom thiab nqus, thiab cov thev naus laus zis tseem ceeb tau raug kho, tus qauv tswj hwm los ntawm Komatsu cov khoom siv thev naus laus zis hauv xyoo 1980 thiab 1990 tau tsim.Indian bulldozer saw Hoobkas
Txij li thaum xyoo 1960, muaj txog plaub tus neeg tsim khoom hauv kev lag luam bulldozer.Yog vim li cas yog vim li cas cov kev xav tau ntawm cov khoom siv bulldozer yog siab, qhov nyuaj yog qhov zoo, thiab cov khoom loj yuav tsum muaj peev txheej loj.Yog li ntawd, cov lag luam zoo tib yam tsis tuaj yeem koom nrog yooj yim.Txawm li cas los xij, nrog kev txhim kho ntawm kev ua lag luam, txij li "Yim Tsib Xyoo Plan", qee lub tuam txhab loj thiab nruab nrab hauv Suav teb tau pib ua haujlwm bulldozers raws li lawv tus kheej lub zog, xws li Inner Mongolia No.1 Machinery Factory, Xuzhou. Loader Factory, thiab lwm yam, thiab nthuav dav pab pawg neeg ua lag luam bulldozer.Nyob rau tib lub sijhawm, cov lag luam me me tau pib poob qis vim kev tswj tsis tau zoo thiab qhov xav tau los hloov kho kev lag luam, thiab qee qhov tau thim tawm ntawm kev lag luam.Tam sim no, domestic bulldozer tuam ntxhab feem ntau suav nrog Shantui Siv Machinery Co., Ltd., Hebei Xuanhua Siv Machinery Co., Ltd., Shanghai Pengpu Machinery Factory Co., Ltd., Tianjin Siv Machinery Factory, Shaanxi Xinhuang Industrial Machinery Co., Ltd. ., Yituo Siv Machinery Co., Ltd., thiab lwm yam Ntxiv rau kev tsim cov bulldozers, cov tuam txhab saum toj no kuj tau pib koom nrog rau kev tsim khoom ntawm lwm cov khoom siv tshuab, xws li Shantui, uas kuj ua rau txoj kev rollers, graders, excavators. , loaders, forklifts, thiab lwm yam Indian bulldozer saw Hoobkas
