Pob tseg traileryog qhov tseem ceeb rau kev khawb av, kev tsim kho, thiab kev tsim kho vaj tse, nrog 60-tuj thiab 120-tuj qauv uas sawv cev rau qhov hnyav -cov dej num tiers. Lub pob pov tseg trailer's "tonnage" yog hais txog nws cov peev txheej them nqi (max cargo hnyav tsis suav nrog tare hnyav), txiav txim siab los ntawm cov qauv siv zog thiab cov qauv kev nyab xeeb. Cov qauv 60-tuj yog nruab nrab-heavy-duty, ntsuas ntawm 60,000 kg (± 5% variation) nrog tare hnyav ntawm 7,600–13,650 kg (GVW 67,600–73,650 kg) thiab feem ntau yog 3-4 axles (txhua qhov hnyav ntawm 13–16 tons). Nyob rau hauv sib piv, 120-tuj hnyav-lub luag hauj lwm trailer yog ntsuas ntawm 120,000 kg, nrog ib tug ntau dua tare hnyav (20,000-65,000 kg, GVW Ntau tshaj los yog sib npaug rau 185,000 kg rau mining) thiab tsuas yog 6 axles los tuav hnyav hnyav.
Lub peev xwm thauj khoom tiag tiag ntawm ob qho qauv yog nyob ntawm cov khoom siv, cov khoom siv, thiab cov kev cai. 60- tuj trailers siv siab- lub zog steel (Q345 / T700) rau kev sib npaug, 3-4 qag (Fuwa / BPW) nrog nplooj / cua ncua, thiab HYVA thooj voos kheej kheej ({6} qauv 110 5+1) siab-tensile steel nrog cov kab hluav taws xob ntxiv, 6 axles nrog hnyav- haujlwm tawm- txoj kev ncua, thiab muaj zog dua 6+1/7+1 150- lub tog raj kheej hydraulic. Kev txwv txoj kev hnyav feem ntau txhais tau tias 60-tuj tsheb thauj khoom tsis tuaj yeem nqa lawv cov nqi tag nrho, thaum 120-tuj units feem ntau yog siv tawm-txoj kev-feem ntau ntawm cov chaw mining-thiab xav tau kev tso cai tshwj xeeb yog tias lawv yuav tsum taug kev ntawm txoj kev pej xeem. Ob hom kuj ua haujlwm sib txawv: 60-tujpov tseg trailerhloov pauv tau txaus rau kev tsim kho, nruab nrab- kev ua haujlwm tsuas me me, thiab cov phiaj xwm kev tsim kho vaj tse, tuav ob qho tib si paving txoj kev thiab teeb tawm - txoj kev. Ntawm qhov tod tes, 120-tuj trailer yog tsim tshwj xeeb rau hnyav- cov haujlwm hnyav xws li loj- nplai mining, quarrying, thiab loj hauv av txav, thiab lawv feem ntau xav tau siab - tsheb laij teb kom ua haujlwm tau zoo hauv kev teeb tsa kev tawm.
Hauv kev siv tswv yim, 60- tuj trailers yog pheej yig dua thiab roj- ua haujlwm tau zoo, ua rau lawv zoo haum rau kev mus ncig nrog cov khoom nruab nrab; lawv cov yam ntxwv kev nyab xeeb yog tus qauv thiab txhim khu kev qha rau txhua hnub hnyav - siv lub luag haujlwm. Thaum 120-tuj tsheb thauj khoom raug nqi ntau dua thiab tswj hwm, lawv txuag nyiaj hauv lub sijhawm ntev rau kev thauj khoom hnyav hnyav los ntawm kev txiav cov nqi mus ncig uas xav tau. Lawv kuj tuaj nrog kev txhim kho kev nyab xeeb los tswj lawv qhov hnyav hnyav. Piv txwv li, 60-tontsheb thauj khoomua kom muaj qhov sib npaug zoo ntawm qhov yooj yim thiab nqa peev xwm rau nruab nrab- cov haujlwm loj, thaum 120- tuj trailers yog tsim los tswj cov khoom hnyav hauv qhov hnyav off-road. Thaum xaiv ntawm ob hom khib nyiab no, koj yuav xav txog ntau npaum li cas cov khoom thauj koj yuav tsum tau txav mus los, thaj chaw uas koj yuav siv lub tsheb thauj khoom, thiab cov cai hauv zos.
