Vim muaj kev nce ntxiv thiab kev sib txawv ntawm kev thov hauv tsev rau hydraulic excavators, kev hloov kho ntawm cov khoom lag luam ntawm cov tuam txhab loj thiab nruab nrab hauv lub xeev tau cuam tshuam qee cov tuam txhab hauv lwm cov kev lag luam hauv kev lag luam los koom nrog kev lag luam hydraulic excavator.
Kev lag luam sab hauv tau taw qhia tias Tuam Tshoj tus tib lub thoob hydraulic excavators yuav tsum tsim nyob rau hauv cov kev taw qhia ntawm tag nrho cov hydraulic siab; lub thoob peev xwm yuav tsum tau tswj ntawm 0.1-15m³; thiab rau qhov loj-scale thiab ntau lub thoob excavators, vim yog qhov yuav tsum tau muaj siab rau kev tsim khoom thiab kev sib dhos ntawm cov khoom siv hydraulic, kev tsim kho qhov chaw qhov sib txawv tseem yog cov neeg kho tshuab. Kev tshawb fawb thiab kev siv tshuab electro-hydraulic tswj yuav tsum tau pib kom paub txog qhov automation ntawm hydraulic excavator ua haujlwm.
kuv lub teb chaws pib tshawb fawb thiab tsim cov khoom siv excavator thaum xyoo 1960s. Tom qab ntau tshaj 40 xyoo, tshwj xeeb tshaj yog ntau tshaj 30 xyoo ntawm kev hloov kho thiab qhib, Tuam Tshoj txoj kev lag luam excavator tau tsim tshwj xeeb sai heev. Raws li cov ntaub ntawv los ntawm National Bureau of Statistics, nyob rau hauv 2010, muaj 252 tuam txhab uas muag saum toj no tsim loj loj nyob rau hauv Tuam Tshoj lub excavator manufacturing kev lag luam, nrog muag ntawm 169.785 billion yuan thiab cov khoom muag profits ntawm 25.367 billion yuan, tag nrho cov nyiaj tau los ntawm 21.406 billion yuan, ib xyoo-rau-xyoo nce ntau tshaj 80 feem pua.
Tuam Tshoj excavator lag luam loj hlob ntawm tus nqi nruab nrab ntawm 30 feem pua, dhau los ua ib lub lag luam loj tshaj plaws hauv ntiaj teb. Los ntawm txoj kev xav ntawm txoj kev loj hlob, Tuam Tshoj yog nyob rau hauv lub ncov lub sij hawm ntawm infrastructure kev tsim kho nyob rau hauv txoj kev tsheb thauj mus los, lub zog thiab dej txuag, kev tsim kho hauv nroog thiab lwm yam, thiab kev lag luam xav tau rau excavators yog nce xyoo los ntawm lub xyoo. Kev loj hlob txhua xyoo nce mus txog 74.5 feem pua.
Thaum kawg ntawm xyoo 2010, cov tuam txhab loj hauv tebchaws tau nthuav dav lawv cov peev txheej ntawm excavators ib qho tom qab, thiab lwm lub tuam txhab tau qhib cov tshuab excavators ib tom qab, sim tsav cov tuam txhab cov nyiaj tau los ntawm kev loj hlob sai ntawm kev lag luam excavator. Qhov tseeb, xav txog ob qho tib si kev pheej hmoo thiab cov txiaj ntsig, cov nyiaj qiv nyiaj hauv tuam txhab nyiaj tsis ua haujlwm hauv kev txhawb nqa kev tsim vaj tsev pheej yig, uas ua rau tsis ncaj ncees rau kev tsim kho tshuab kev muag khoom hauv lub quarter thib ob ntawm xyoo 2011. Lub Tsib Hlis 2011, kev muag khoom hauv tsev ntawm excavators. yog 13,956 units, ib xyoo-rau-xyoo txo ntawm 12.4 feem pua, thiab thawj lub hli poob yog xyoo-rau-xyoo; kev muag khoom los ntawm Lub Ib Hlis mus txog Lub Tsib Hlis yog 115,589 units, ib xyoos ib zaug nce ntawm 38.1 feem pua, qhov txo qis ntawm 12 feem pua ntawm lub Ib Hlis mus txog Plaub Hlis.
Cov ntaub ntawv qhia tau hais tias txij lub Ib Hlis mus txog Lub Tsib Hlis 2011, kev lag luam sib koom ntawm cov khoom lag luam hauv tsev tau nce ntxiv mus rau 37 feem pua. Sany Heavy Kev Lag Luam, uas yog thawj zaug hauv kev tsim khoom hauv tsev excavator, tau mus txog qhov ntsuas ntawm kev tsim khoom txhua xyoo thiab kev muag khoom ntawm kaum tawm txhiab units, thaum lub peev xwm tsim tau ntawm plaub sab saum toj hauv kev lag luam tau mus txog qib ntau dua 4, { {3}} units ib xyoo. Tus nqi ntawm lub peev xwm nthuav dav ntawm lwm lub tuam txhab kuj tseem muaj zog heev. Nyob rau theem tom ntej, kev ua lag luam sib koom ntawm cov khoom lag luam hauv tebchaws excavators rau cov tshuab tuaj txawv teb chaws thiab cov xov tooj ntawm tes thib ob yuav dhau los ua tus qauv.
Raws li cov ntaub ntawv nthuav tawm los ntawm Kev Tsim Kho Machinery Online, txij li lub Cuaj Hli 2014, tag nrho ntawm 1,006 lub tshuab excavators qis dua 6 tons tau muag, ntawm cov khoom txawv teb chaws. muaj kev sib koom ua lag luam ntawm 55. Tsis tas li ntawd, qhov muag ntim ntawm excavators saum toj no 6 tons yog 3,139 units, kev lag luam feem ntawm cov khoom lag luam txawv teb chaws yog 61.0 feem pua, thiab kev lag luam feem ntawm cov hom lag luam hauv tsev tsuas yog 39.0 feem pua. Raws li cov ntaub ntawv ntawm Sany Heavy Kev Lag Luam, los ntawm 2011 txog 2013, kev lag luam hauv teb chaws ntawm lub tuam txhab excavators tau nce mus txog 11.56 feem pua, 15.8 feem pua thiab 13.7 feem pua nce, tshaj Carter thiab qeb duas hauv kev lag luam. Nws txoj kev lag luam feem ntau dua 15 feem pua. Cov neeg sab hauv kev lag luam ntseeg tias lub tuam txhab yeej thawj qhov chaw xyoo no thiab ua tiav "plaub xyoo muag khoom" yam tsis muaj qhov xav tsis thoob.
Ntawm tag nrho, cov tswv cuab hauv tsev ntawm excavators tsawg, tab sis cov khoom lag luam yog siab. Cov qauv kev muag khoom feem ntau yog raws li kev qiv nyiaj txiag lossis qiv nyiaj hauv tuam txhab nyiaj. Thaum cov credit tau so, kev muag khoom ntawm excavators yuav yog cov khoom lag luam zoo tshaj plaws kom rov zoo. Nws tuaj yeem kwv yees tias nyob rau hauv 2011-2013, nrog kev rov qab los ntawm Suav kev lag luam hauv ntiaj teb thiab kev nrawm ntawm cov vaj tse thiab kev tsim kho nroog, kev muag khoom ntawm ntau lub tonnages tseem yuav loj hlob ntxiv. Lub tshuab yuav loj hlob ntawm kev loj hlob ntawm ntau tshaj 15 feem pua.
Raws li kev sib tw hauv kev lag luam excavator txuas ntxiv mus ntxiv, kev sib koom ua ke thiab kev yuav khoom thiab kev lag luam peev ntawm cov tuam txhab loj excavator tau dhau los ua ntau thiab ntau dua, thiab cov tuam txhab tsim khoom lag luam zoo heev hauv tsev tau them nyiaj ntau dua rau kev tshawb fawb ntawm kev lag luam kev lag luam, tshwj xeeb tshaj yog kev lag luam loj hlob ib puag ncig thiab cov khoom lag luam. Cov neeg yuav khoom qhov kev tshawb fawb tob. Nws yog precisely vim hais tias ntawm no hais tias ib tug loj tus naj npawb ntawm domestic excavator zoo heev hom tau nce sai heev thiab tau maj mam ua cov thawj coj nyob rau hauv excavator manufacturing kev lag luam nyob rau hauv Tuam Tshoj thiab txawm lub ntiaj teb no.
