Kev tsim khoom yuav tsum tau ua rau qis- txaj trailers feem ntau cuam tshuam rau qhov tseeb thiab lub zog tswj ntawm lawv cov qauv tsim. Raws li cov tub ntxhais load-cov kabmob tivthaiv, lub chassis feem ntau yog tsim los ntawm siab- zog, qis- alloy steel lossis tshwj xeeb cov qauv steel; Lub qhov ntev ntawm qhov sib xws yuav tsum tau khaws cia thaum lub sij hawm npaj cov khoom, txiav, thiab tsim kom tsis txhob muaj qhov sib npaug ntawm cov khoom siv los ntawm kev ua haujlwm tsis raug. Vuam yog cov txheej txheem tseem ceeb; longitudinal beams, crossbeams, thiab stiffeners xav tau ob qho tib si tack welding thiab tag nrho vuam nyob rau hauv nruj raws li kev specifications. Welds yuav tsum tsis tu ncua thiab zoo ib yam, dhau qhov tsis yog- kev sim ua kom puas tsuaj los xyuas kom tsis muaj qhov tsis xws luag xws li cov kab nrib pleb lossis slag suav nrog, yog li lav lub tsheb kev ruaj ntseg thiab thauj khoom- kev nyab xeeb.
Tsawg- txaj trailers xav tau siab precision nyob rau hauv kev sib dhos thiab kev koom ua ke ntawm lawv ntau lub tshuab. Thaum lub sij hawm installation, lub ncua kev kawm ntawv, axles, thiab braking systems yuav tsum tau ua tib zoo sib xws thiab leveled los tiv thaiv cov teeb meem xws li tsheb rub los yog txawv txav log tsheb thaum lub sij hawm ua hauj lwm. Tsis tas li ntawd, qhov qis - txaj qauv yuav tsum nruj flatness; post- kev sib dhos ua ke yog qhov tseem ceeb kom ntseeg tau tias cov khoom thauj - cov kabmob nto yog tsis muaj qhov tseem ceeb deformation lossis twisting, ua tau raws li qhov yuav tsum tau muaj rau kev thauj mus los ntawm cov khoom hnyav lossis cov thawv loj.
Kev kho saum npoo thiab tiv thaiv - cov txheej txheem corrosion yog qhov tseem ceeb ntawm kev tsim khoom. Tom qab vuam thiab kev sib dhos zaum kawg, lub tsheb thauj khoom tau raug txhaj tshuaj blasting lossis sandblasting kom tshem tawm cov oxide txheej, ua raws li kev siv tshuaj tiv thaiv - xeb primer thiab topcoat. Qee cov qauv siab -kawg siv ntau- txheej tiv thaiv- txheej txheem corrosion lossis electrophoretic txheej los txhim kho cov kav dej hauv av, ntsev, lossis lwm qhov chaw hnyav. Thaum kawg, lub tsheb ua tiav tau dhau los kuaj kev thauj khoom zoo li qub thiab kev sim kev sim kom paub tseeb tias txhua qhov kev ua haujlwm tsis tau raws li cov qauv tsim ua ntej lub tsev tso tawm ntawm lub hoobkas.
