Cia peb fim nws: taug kev mus rau hauv lub tsheb thauj khoom siv ntau tuaj yeem xav tias zoo li ua si qhov kev ua si siab ntawm poker. Koj pom ib qho zoo nkauj, gleaming 53-foot reefer trailer zaum hauv qab hnub tav su. Tus nqi tag zoo li ntxim nyiam kawg - tej zaum nws yog 40% pheej yig dua li kev yuav ib chav tsev tshiab ncaj nraim los ntawm lub Hoobkas hauv pem teb. Koj lub hlwb paub txog nyiaj txiag tam sim ntawd pib xam nyiaj npaum li cas koj yuav txuag tau, thiab sai npaum li cas qhov trailer yuav pib txhawb koj cov nyiaj ntsuab txhua hnub.
Tab sis ntawm no yog tus ntes. Nyob rau hauv lub ntiaj teb mobile txias cia, ib tug pheej yig trailer tuaj yeem ua qhov yuam kev kim tshaj plaws uas koj lub lag luam puas tau ua.
Kuv yuav tsis hnov qab hu kuv tau txais los ntawm tus tswv-tus neeg ua haujlwm npe hu ua Marcus ob peb xyoos dhau los. Marcus nyuam qhuav tso nws txoj sia tseg rau hauv kev siv rub-qab lub freezer trailer nws pom hauv online. Nws ntsia immaculate rau sab nraum. Tab sis thaum lub sij hawm nws thawj zaug kev lag luam thauj khoom - txav cov khoom xa tuaj ntawm cov khoom noj khoom haus qib siab thoob plaws Arizona - qhov kub sab hauv tsis kam poob qis dua 45 ° F. Lub compressor tau khiav ntawm lub peev xwm siab tshaj plaws, lub cav tau qw, tab sis cov cua txias tau ploj mus rau hauv huab cua nyias. Marcus poob cov khoom thauj, poob nws cov neeg siv khoom, thiab tau daig nrog daim nqi kho mob loj.
Thaum Marcus hu rau peb ntawm ZZKNOWN, peb tau pab nws kuaj qhov teeb meem: tus tswv yav dhau los tau tsis quav ntsej cov phab ntsa sab hauv delamination, tig lub trailer zoo nkauj rau hauv lub qhov cub uas tsis muaj txiaj ntsig zoo.
Peb tsis xav kom tshwm sim rau koj. Txawm hais tias koj yog tus tswv lag luam ywj pheej sim ntsuas koj txoj kev faib khoom lossis tus neeg yuav khoom siv nyiaj txiag uas tab tom nrhiav rau lub cuab yeej cuab tam uas ntseeg tau, phau ntawv qhia no yog koj tus kheej, phooj ywg-rau-phooj ywg txoj hauv kev. Cia peb zaum thiab saib qhov tseebsoj ntsuam reefer trailer checklistkoj yuav tsum khiav dhau ua ntej koj puas tau muab ib duas las ntawm koj cov nyiaj khwv tau los nyuaj.
Cia peb saib ob sab ntawm lub npib vim tias muaj qhov zoo tiag tiag yog tias koj paub tias koj ua dab tsi.
Qhov khoom plig loj: Kev txuag peev.Qhov pom tseeb tshaj plaws yog vim li casyuav khoom siv tub yees traileryog cov nyiaj khaws cia ua ntej. Ib qho kev lag luam tshiab reefer tuaj yeem cuam tshuam loj rau kev pib ua lag luam credit line. Kev yuav khoom siv tso cai rau koj hla txoj kev nkhaus ntawm cov cuab yeej depreciation, ua kom koj cov nyiaj siv ua haujlwm qis thiab koj lub lag luam agile.
Qhov Kev pheej hmoo loj heev: Ncua Kev Ua Haujlwm Tsis Txaus.Tsis zoo li tus qauv qhuav van trailer-uas yog qhov tseem ceeb tsuas yog lub thawv txhuas ntawm lub log-lub reefer trailer yog ib qho nyuaj ntawm thermal thiab mechanical engineering. Koj tsis yog yuav cov khoom siv hlau xwb; Koj tab tom yuav ib qho thaiv thaiv thaiv, lub tshuab hluav taws xob ywj pheej, lub voj voog me me, thiab cov ntsuas kub hauv computer. Yog tias ib qho ntawm cov tshuab no tau raug tsis saib xyuas, koj tau txais lwm tus neeg lub tshuab hluav taws xob pheej yig.
Txhawm rau pab koj sib npaug cov kev pheej hmoo no, peb tau siv sijhawm ntau xyoo los kho cov txheej txheem thiab cov khoom siv kho tshuabntawmZZKNOWNcais cov gems zais ntawm cov nyiaj pits. Cia peb saib cov chaw tseem ceeb uas koj yuav tsum tau tshuaj xyuas thaum koj lub cev taug kev.
Ua ntej koj txawm tig lub cav tub yees, koj yuav tsum xyuas kom meej lub cev qauv ntawm lub trailer. Yog tias cov qauv raug cuam tshuam, chav txias txias zoo tshaj plaws hauv ntiaj teb yuav tsis txuag koj cov khoom thauj.
Rwb thaiv tsev phab ntsa yog tsim zoo li cov qhaub cij: ib txheej tuab ntawm high-density polyurethane ua npuas ncauj yog sib txuas ncaj qha ntawm cov tawv nqaij txhuas sab hauv thiab cov ntaub hauv fiberglass. Nyob rau tib lub sijhawm, kev cuam tshuam hnyav, kev nkag mus ntawm cov dej noo, lossis kev sib tw ntawm cov txheej txheem tuaj yeem ua rau cov txheej txheem sib cais. Qhov no hu uadelamination.
Kev kuaj lub cev:Taug kev ntawm sab nraud thiab sab hauv phab ntsa ntawm lub trailer thiab siv koj txhais tes los nias kom ruaj khov rau cov panels. Koj puas xav tias muaj "npua", sags, lossis pob pob?
Lub Suab Test:Nqa ib lub hnab yas me me los yog siv koj cov pob qij txha kom maj mam muab tso rau ntawm phab ntsa. Ib qho kev noj qab haus huv, kev sib koom ua ke ntawm lub vaj huam sib luag yuav ua rau cov khoom muaj zog, npub. Ib tug delaminated vaj huam sib luag yuav suab hollow, mos, los yog echoey.
Kuv Qhov Kev Paub:Yog hais tias ib tug trailer muaj ib qho tseem ceeb delamination, nws thermal efficiency yog mus tas li puas. Lub tshuab cua txias yuav tsum tau ua haujlwm ob zaug ntxiv kom ua kom txias txias, ua kom koj cov roj kev lag luam puas tsuaj thiab hnav tawm lub compressor ntxov ntxov.
Txias trailerpem teb coj ib tug kiag li ntaus. Hnyav forklifts yob hla lawv txhua hnub, thiab ya raws los ntawm cov khoom thauj khov tas li nyob rau hauv cov grooved raws.
Nrhiav Forklift Cracks:Tshawb xyuas lub nraub qaum ntawm hauv pem teb - thaj chaw uas cov forklifts nkag los ntawm qhov chaw thau khoom. Tshawb nrhiav cov kab nrib pleb sib sib zog nqus, cov txheej txheem sagging, lossis xoob aluminium welds.
Tshawb xyuas Subfloor Base:Nkag mus rau hauv qab lub trailer nrog lub teeb nyem muaj zog. Saib ze ntawm cov neeg hla kev txhawb nqa hauv pem teb. Yog tias cov dej tau ntws los ntawm cov txheej txheem aluminium sab hauv rau hauv cov txheej txheem rwb thaiv tsev, cov khoom siv hauv qab yuav rot, ua rau hauv pem teb sag txaus ntshai nyob rau hauv hnyav loads.
Qhov sib txawv me me hauv lub qhov rooj kaw tom qab tuaj yeem ua rau ntau txhiab nyiaj hauv kev puas tsuaj rau cov khoom thauj. Nws tso cai rau huab cua sov, huab cua nyob ib puag ncig kom tsis tu ncua nkag mus rau hauv lub trailer, tsim cov dej khov loj loj ntawm koj cov coils txias.
Lub hnub ci Test:Nkag mus rau hauv lub trailer tag nrho, rub lub qhov rooj tom qab kaw tag, thiab khi lawv cia. Tua koj lub teeb nyem thiab tos koj ob lub qhov muag los kho qhov tsaus ntuj. Saib ze ntawm qhov chaw ntawm lub qhov rooj. Koj puas pom cov slivers ntawm nruab hnub nrig tho los ntawm cov roj hmab gaskets? Yog tias koj pom lub teeb, koj muaj cua nkag.
Flexibility Check:Hnov cov roj hmab gaskets nrog koj cov ntiv tes. Puas yog lawv muag, yoog raws, thiab tsis muaj zog? Los yog lawv qhuav, nkig, tawg, thiab ncuav nyob rau hauv qhuav av? Hloov tag nrho cov khoom lag luam ntawm lub qhov rooj tsis tuaj yeem ua tsis tau, tab sis nws yog tus nqi koj yuav tsum tau sib tham txog tus nqi yuav khoom zaum kawg.
