Keeb kwm kev loj hlob ntawm crawler bulldozers
Track-type tractor (tseem hu ua crawler dozer) tau ua tiav los ntawm American Benjamin Holt hauv xyoo 1904. Nws tau tsim los ntawm kev txhim kho tib neeg-lifting bulldozer nyob rau hauv pem hauv ntej ntawm lub tsheb laij teb crawler.Lub zog thaum ntawd yog lub tshuab hluav taws xob.Tom qab ntawd, crawler-hom bulldozers uas tau tsav los ntawm lub zog hluav taws xob thiab roj av cav tau ua tiav tiav, thiab lub tshuab bulldozer 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, 5Holt Manufacturing Company thiab CL Best Bulldozer Company tau koom ua ke los ua Caterpillar Bulldozer Company, dhau los ua lub ntiaj teb thawj cov khoom siv bulldozer.Nyob rau hauv 1931, thawj batch ntawm 60 bulldozers nrog diesel xyaw tau ntse dov tawm ntawm cov kab ntau lawm.Nrog rau kev nce qib ntawm kev siv thev naus laus zis tas li, txhua lub tsheb bulldozers tau siv los ntawm lub tshuab hluav taws xob, thiab cov tshuab bulldozer thiab scarifiers yog txhua tus nqa los ntawm hydraulic thooj voos kheej kheej.
Ntxiv rau cov bulldozers hom crawler, bulldozers kuj muaj log tsheb-hom bulldozers, uas tshwm sim li kaum xyoo tom qab tshaj crawler-hom bulldozers.Vim hais tias crawler bulldozers muaj kev ua tau zoo adhesion thiab tuaj yeem siv ntau dua traction, ntau thiab ntau ntawm lawv cov khoom nyob deb tshaj cov log tsheb bulldozers hauv tsev thiab txawv teb chaws.
Thoob ntiaj teb, Caterpillar yog lub tuam txhab tsim khoom loj tshaj plaws hauv ntiaj teb.Nws cov crawler bulldozers suav nrog 9 series loj, nruab nrab thiab me D3-D11, qhov loj tshaj plaws D11 RCD, thiab lub cav diesel cav flywheel zog mus txog 634kw;Nyiv Lub tuam txhab Komatsu thib ob, thiab nws tsuas yog pib qhia thiab tsim D50 crawler bulldozer hauv xyoo 1947.
Muaj 13 series ntawm crawler bulldozers, los ntawm D21-D575, qhov tsawg tshaj plaws yog D21, lub diesel cav flywheel zog yog 29.5kw, qhov loj tshaj plaws yog D575A-3SD, lub diesel cav flywheel zog mus txog 858kw, nws kuj yog lub loj tshaj plaws bulldozer nyob rau hauv lub ntiaj teb;Tus yam ntxwv bulldozer chaw tsim tshuaj paus yog lub teb chaws Yelemees Liebheer Group (Liebheer), uas nws bulldozers tag nrho cov tsav los ntawm hydrostatic siab.Tom qab ntau tshaj kaum xyoo ntawm kev tshawb fawb thiab kev loj hlob, thev naus laus zis tau pib ua qauv hauv xyoo 1972, thiab pib tsim khoom loj hauv xyoo 1974. PR721-PR731 thiab PR741 hydrostatic tsav crawler bulldozer, vim muaj kev txwv ntawm hydraulic Cheebtsam, nws lub zog siab tshaj plaws tsuas yog 295Kw ntawm tam sim no, tus 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.Ob peb lwm cov tuam txhab txawv teb chaws ntawm crawler bulldozers, John Deere, Case, New Holland thiab Deresta, kuj muaj cov thev naus laus zis ntau lawm.
Kev tsim cov bulldozers hauv Suav teb tsuas yog pib tom qab kev tsim ntawm Tuam Tshoj Tshiab.Thaum pib, bulldozers tau nruab rau ntawm cov tsheb laij teb ua liaj ua teb.Nrog rau txoj kev loj hlob ntawm lub teb chaws kev lag luam, 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 ntxiv.Txawm hais tias kuv lub teb chaws qhov nruab nrab thiab loj crawler bulldozer manufacturing kev lag luam tau tsim zoo heev, nws tsis muaj peev xwm ua tau raws li cov kev xav tau ntawm kev lag luam hauv teb chaws.xav tau.
Txog rau qhov kawg no, txij li xyoo 1979, kuv lub teb chaws tau ua tiav cov thev naus laus zis ntau lawm, cov txheej txheem kev qhia tshwj xeeb, cov qauv kev qhia thiab cov khoom siv ntawm cov tshuab bulldozers los ntawm Komatsu Corporation ntawm Nyiv thiab Caterpillar Corporation ntawm Tebchaws Meskas.Ib qho qauv ua los ntawm Komatsu cov khoom siv thev naus laus zis hauv xyoo 1980 thiab 1990s.
Los ntawm xyoo 1960 mus txog rau tam sim no, tus naj npawb ntawm cov neeg tsim khoom hauv tsev ntawm bulldozers tau ruaj khov ntawm li 4. Qhov laj thawj yog vim li cas cov khoom siv bulldozer yog siab thiab nyuaj, thiab cov khoom loj yuav tsum muaj peev txheej loj, yog li cov lag luam zoo tib yam tsis txhob twv. teem ko taw yooj yim.Txawm li cas los xij, nrog txoj kev loj hlob ntawm kev lag luam, pib los ntawm "Yim Tsib Xyoo Plan", qee lub tuam txhab loj thiab nruab nrab hauv tsev tau pib ua haujlwm bulldozers ib txhij raws li lawv tus kheej lub zog, xws li Inner Mongolia No. 1 Machinery Factory, Xuzhou. Loader Factory, thiab lwm yam, nthuav dav pab pawg neeg ua lag luam bulldozer.
Nyob rau tib lub sijhawm, kuj tseem muaj cov lag luam me me uas tau pib poob qis vim kev tswj tsis tau zoo thiab kev xav tau ntawm kev lag luam kev loj hlob, thiab qee qhov twb tau thim tawm ntawm kev lag luam.
Tam sim no, lub tuam txhab tseem ceeb hauv tsev ntawm bulldozers yog:
Shantui Siv Machinery Co., Ltd., Hebei Xuanhua Siv Machinery Co., Ltd., Shanghai Pengpu Machinery Factory Co., Ltd., Tianjin Siv Machinery Factory, Shaanxi Xinhuang Machinery Co., Ltd., Yituo Siv Machinery Co., Ltd. .,lwm.
Ntxiv nrog rau kev tsim cov bulldozers, cov tuam txhab uas tau hais los saum toj no kuj tau pib taw rau kev tsim khoom ntawm lwm yam khoom siv tshuab.Piv txwv li, Shantui kuj tsim txoj kev rollers, graders, excavators, loaders, forklifts, thiab lwm yam.
