Tus nqi tsheb thauj khoom dumper tsuas yog muaj txiaj ntsig thaum cov tsheb tau hais tseg muaj tib qho kev qhia thiab kev lag luam. Ob qhov kev muab yuav siv tib lub qag mis thiab lub cev zoo sib xws tsis tau sib txawv hauv chassis configuration, cav thiab emissions pob, kis tau tus mob, qag ratings, lub cev khoom, hydraulic system, log tsheb, soj ntsuam cov ntaub ntawv, spare qhov chaw, lub sij hawm tus me nyuam thiab cov nqe lus nug. Daim duab qis dua tuaj yeem piav qhia txog qhov me me dua li qhov kev yuav khoom zoo dua. Ua ntej sib piv tag nrho, cov neeg yuav khoom xav tau ib lub sijhawm RFQ thiab cov npe sib txawv ntawm tus neeg muag khoom. Thaum cov ciam teb raug kho, tus nqi, lub sijhawm ua haujlwm thiab cov nqe lus them nqi tuaj yeem txiav txim siab ntawm qhov sib piv.

Pib nrog tus ciam teb hais, tsis yog tag nrho

Tus nqi rau lub tsheb thauj khoom tuaj yeem piav qhia ntau yam sib txawv: lub tsheb ua tiav txoj kev npaj, lub chassis nrog lub cev hauv zos, lub tsheb thauj khoom tsis muaj cov ntaub ntawv xa tawm, lossis ib chav tsev hais tawm ntawm tus neeg muag khoom thaj chaw. Txawm tias lo lus "tus qauv teeb tsa" tsis tuaj yeem ntseeg tau tshwj tsis yog tias tus qauv raug txheeb xyuas hauv kev sau ntawv.

Yog li thawj qhov kev sib piv yuav tsum nug seb tus neeg muag khoom tau suav nrog dab tsi. Ib qho lus hais cais lub tsheb, lub cev thiab cov khoom siv tipping los ntawm kev xaiv qhov chaw, tshuaj xyuas kev ua haujlwm, ntim khoom, kev thauj mus los hauv av thiab thoob ntiaj teb freight. Nws kuj txheeb xyuas qhov chaw xa khoom thiab lub sijhawm ua lag luam kom meej. Kev thauj khoom them los ntawm tus muag khoom tsis tas txhais tau tias kev pheej hmoo hloov pauv ntawm qhov chaw, yog li qhov chaw muaj npe thiab txoj cai xaiv Incoterms yuav tsum tshwm sim ua ke hauv qhov kev thov.

Cov neeg yuav khoom tshuaj xyuas qhov dav dua dump tsheb ntau rau mining thiab kev tsim kho tej yaam num yuav tsum siv tib tus ciam teb rau txhua qhov shortlisted configuration. Txwv tsis pub, ib qho kev tshem tawm los ntawm ib qho kev thov tuaj yeem rov tshwm sim tom qab raws li kev xaiv, tus nqi hauv zos lossis kev ua haujlwm qeeb.

Lub tsheb specification hloov tus nqi yuav khoom thiab kev ua haujlwm haum

Axle configuration yog tus nqi tsim nyog tsav tsheb, tab sis nws tsis yog txoj cai xaiv tiav. A 4 × 2, 6 × 4, 6 × 6 lossis 8 × 4 tsheb thauj khoom sib txawv ntawm kev sib tw, kev thauj khoom raug cai, tig qhov chaw, chassis loj thiab lub cev ntev. Qhov kev xaiv zaum kawg yog nyob ntawm seb lub tsheb yuav ua haujlwm feem ntau ntawm txoj kev pej xeem, kev tsim kho kev sib cog lus, txoj kev quarry los yog qhov chaw mos mine.

Lub cav tso zis kuj xav tau cov ntsiab lus. Daim duab horsepower ntau dua tuaj yeem nce qhov kev hais tawm thawj zaug, tab sis txoj hauv kev gradient, tsheb loj, sib kis tau tus mob thiab xav tau ceev txiav txim siab seb qhov tso zis puas muaj txiaj ntsig. Tib yam siv rau emission configuration.
