Thawv thauj cov tsheb thauj mus los yuav tsum tau tshawb xyuas sai ntawm cov khoom tseem ceeb ua ntej thiab tom qab txhua qhov kev mus ncig. Cov kev kuaj xyuas no suav nrog kev sib txuas ntawm kingpin thiab lub log thib tsib, lub log tsheb hnav thiab kev nce nqi siab, muaj peev xwm ua rau huab cua nkag hauv lub braking system, thiab kev ua haujlwm zoo ntawm cov teeb pom kev zoo thiab hluav taws xob. Kev saib xyuas tshwj xeeb kuj yuav tsum tau them nyiaj rau lub thawv kaw cov txheej txheem kom ntseeg tau tias lawv tsis xoob lossis deformed, yog li tiv thaiv kev nyab xeeb thaum thauj.
Kev saib xyuas yuav tsum tau ua tsis tu ncua ntawm lub braking system, ncua kev kawm ntawv, thiab axles. Rau lub braking system, cov dej uas muaj nyob rau hauv cov huab cua reservoirs yuav tsum tau ntws tawm tsis tu ncua, thiab cov ntaub thaiv npog yuav tsum tau kuaj xyuas kom hnav thiab hloov tam sim ntawd. Cov khoom raug tshem tawm -txawm tias cov nplooj hlav los yog cov tshuab cua ncua kev kawm - yuav tsum tau kuaj xyuas cov kab nrib pleb, huab cua los yog deformation. Bearings yuav tsum tau lubricated ntawm lub sijhawm teem tseg kom txo qis kev ua haujlwm hnav thiab ua rau lub neej ua haujlwm ntev. Cov haujlwm tu vaj tse no feem ntau yog ua raws li cov txheej txheem teev tseg raws li mais lossis lub sijhawm siv.
Kev tiv thaiv- kev saib xyuas corrosion rau lub chassis thiab kev saib xyuas ntawm tag nrho cov qauv yog qhov tseem ceeb sib npaug. Kev siv ntev ntev tuaj yeem ua rau xeb ntawm qhov trailer qhov chaw uas tshwm sim los ntawm kev sib txhuam, los nag, lossis raug tshuaj ntsev; kev tu txhua hnub, kov- pleev xim rau, los yog kev kho corrosion yog tsim nyog los khaws cov qauv kev ncaj ncees. Rau cov tsheb thauj mus los uas tseem nres rau lub sijhawm ntev, xeb- yuav tsum tau ua raws li kev tiv thaiv kev tiv thaiv, thiab lub tsheb thauj khoom yuav tsum tau txav mus rau ib ntus thaum thauj khoom los tiv thaiv lub log deformation thiab kev qaug dab peg. Kev tu thiab tu ncua sij hawm tseem ceeb txhim kho kev nyab xeeb thiab kev pabcuam lub neej ntawm trailer.
