Kev txhim kho keeb kwm ntawm kev tsim kho tshuab
Kev txhim kho keeb kwm ntawm kev tsim kho tshuab tuaj yeem muab faib ua ob peb theem tseem ceeb, txhua theem nws muaj nws tus kheej thev naus laus zis tshiab thiab kev hloov pauv kev lag luam. cov
kev loj hlob ntxov
Kev txhim kho thaum ntxov ntawm kev tsim kho tshuab tuaj yeem taug qab mus rau Industrial Revolution. Nyob rau xyoo 1860, thawj qhov kev lag luam kiv puag ncig tau pib hauv tebchaws Askiv tau cim qhov pib ntawm lub sijhawm thaum cov tshuab hloov cov cuab yeej siv tes, thiab cov tshuab hluav taws xob tau dhau los ua cov cuab yeej tsim khoom tseem ceeb. Los ntawm qhov kawg ntawm lub xyoo pua 19th mus rau thaum pib ntawm lub xyoo pua 20th, lub ntiaj teb no tau nkag mus rau "Electrical Age". Ntau lub npe nrov siv tshuab xws li Case (1842), Sandvik (1862), Komatsu (1921), Hitachi (1920), Kab ntsig (1920), thiab lwm yam. 1925) thiab lwm tus tau tshwm sim thaum lub sijhawm no.
Tuam Tshoj txoj kev loj hlob keeb kwm
Hauv Suav teb, kev txhim kho cov tshuab tsim kho tau dhau los ntawm kev txom nyem mus rau kev coj noj coj ua hauv ntiaj teb. Thaum pib ntawm lub xyoo pua 20th, Tuam Tshoj txoj kev siv tshuab tsuas yog tso siab rau kev xa khoom, thiab cov khoom lag luam txawv teb chaws tsim cov chaw tsim khoom hauv Suav teb los txhawb txoj kev loj hlob ntawm kev lag luam hauv tsev. Lub ntsiab lus pib ntawm Tuam Tshoj lub "blowout" tuaj yeem taug qab mus rau Western Development thiab kev tsim kho ntawm Qinghai-Tibet Railway. Nyob rau lub sijhawm no, cov cuab yeej siv hauv tsev tau txhim kho kev txawj ntse thiab zoo. Cov cuab yeej siv hauv tsev tau maj mam nyob hauv feem coob ntawm Suav lag luam thiab tau xa tawm mus rau txawv teb chaws.
kev txhim kho niaj hnub
Txoj kev loj hlob ntawm cov tshuab siv niaj hnub no suav nrog kev hloov pauv mus rau kev txawj ntse thiab kev ua haujlwm zoo. Cov cuab yeej siv ntau lawm yog "kev tsiv teb tsaws" los ntawm cov tswv mus rau cov khoom siv, uas txhais tau hais tias kev hloov pauv ntau dua yog tsom rau cov cuab yeej pabcuam thiab cov khoom siv ntxiv es tsis yog cov khoom siv hauv tsev. Tsis tas li ntawd, "14th Tsib Xyoo Plan" lub hom phiaj ntawm Tuam Tshoj kev tsim kho tshuab kev lag luam suav nrog kev txhim kho tag nrho cov theem, txhim kho kev muaj peev xwm tshiab, txhim kho kev ua tau zoo thiab ua haujlwm zoo, thiab txhawb kev tshawb fawb ywj pheej thiab kev tsim cov khoom siv high-end.
Cov npe tshwj xeeb thiab kev tsim kho tshiab
Qee lub npe nrov siv tshuab xws li Caterpillar, Komatsu, thiab Kobelco muaj cov txheej txheem thev naus laus zis tseem ceeb hauv keeb kwm. Piv txwv li, Caterpillar's predecessor HOLT tau tsim thawj lub zog siv hluav taws xob crawler bulldozer hauv xyoo 1904, Komatsu tau tsim lub ntiaj teb thawj hybrid hydraulic excavator hauv xyoo 1957, thiab Kobelco tau qhia txog roj av-hluav taws xob hybrid hauv 2006. Excavator .
txoj cai cuam tshuam
Tsoomfwv Suav txoj cai txhawb nqa kev tsim kho tshuab kev lag luam kuj tseem ua lub luag haujlwm tseem ceeb. Piv txwv li, "14th Tsib Xyoo Plan" npaj lub hom phiaj ntawm kev txhim kho tag nrho cov theem ntawm kev lag luam, ua kom muaj peev xwm ua tau zoo, thiab txhim kho kev ua tau zoo thiab kev ua tau zoo los ntawm 2025. Cov cai no tau txhawb txoj kev ywj pheej ntawm kev lag luam thiab kev lag luam. kev tshawb fawb thiab kev loj hlob ntawm high-end qhov chaw thiab cov khoom, thiab txhawb kev ruaj khov kev lag luam
