1. Ua haujlwm Load txwv rau Round Link Steel Chains
Txawm hais tias koj thauj cov tshuab, siv cov hlua khi, lossis yog nyob rau hauv kev lag luam txiav, nws yog ib qho tseem ceeb kom paub txog cov kev txwv kev ua haujlwm ntawm cov saw hlau uas koj siv. Cov chains muaj qhov txwv tsis pub ua haujlwm- lossis WLL- ntawm kwv yees li ib feem ntawm lawv lub zog tawg (lub zog ntawm cov chains tuaj yeem tiv taus ua ntej lawv tawg).
Qib saw thiab txoj kab uas hla txiav txim siab qhov kev txwv kev ua haujlwm ntawm cov saw hlau. Chain yog embossed nrog ob qib thiab qhov loj kom koj tuaj yeem txiav txim siab nws WLL siv daim ntawv qhia no.
2. Hom saw hlau
Qib 30 yog kev siv ntau yam, kev lag luam nyiaj txiag. Kuj tseem hu ua Qib 30 Pov Thawj Coil Chain, tib neeg siv cov khoom no hauv ntau yam kev lag luam thiab kev ua haujlwm, suav nrog kev tsim teeb pom kev zoo, thaiv cov hlua khi, thiab hauv kev lag luam marine. Nws tsis muaj kev nyab xeeb rau kev nqa lub taub hau. Qib 30 saw yog embossed siv 3, 30, lossis 300.
Kuj hu ua Qib 43 High Test Chain lossis Qib 43 Tow Chain, qhov no muaj ntau hauv kev lag luam nqa thiab txiav ntoo. Tsis txhob siv cov saw no rau kev nqa lub taub hau. Cov saw no suav nrog cov qauv tsim embossed siv 43 lossis G4.
Qib 70 Tsheb thauj mus los, tseem hu ua "Qib 70 Truckers Chain," ua haujlwm hauv kev ruaj ntseg rau kev thauj mus los. Tsis txhob siv cov saw no rau ib qho nyiaj siv ua haujlwm nqa. Cov saw no suav nrog cov qauv tsim embossed siv 7, 70, lossis 700.
Qib 80 Alloy Chain ua haujlwm rau kev nqa lub taub hau vim nws qhov kev tsim kho cua sov. Cov neeg feem ntau siv hom saw no ua ib lub luag haujlwm hnyav nqa saw. Qib 80 saw muaj xws li tsim embossed siv 8, 80, lossis 800.
Raws li cov saw zoo tshaj plaws, nws muaj txog 25% kev ua haujlwm siab dua qhov txwv hla qib 80 saw. Nws muaj kev nyab xeeb rau kev nqa lub taub hau. Qib 100 chains suav nrog cov qauv embossed nrog 10 lossis 100.
Ib yam khoom tshiab nyob rau hauv kev ua lag luam, Qib 120 saw muaj txog li 50% muaj zog tshaj li Qib 80 saw thiab 20% muaj zog dua qib 100 saw. Nws kuj tseem tiv taus kev puas tsuaj ntau dua li Qib 80 thiab Qib 100 chains. Nws muaj kev nyab xeeb rau kev nqa nqa nqa.
3. Kawm paub ntxiv txog qhov sib txawv ntawm qib 70, 80 thiab 100 ntawm no:
Ib lo lus nug uas peb pawg neeg muag khoom hnov los ntawm cov neeg siv khoom txog peb cov khoom lag luam yog "Qhov txawv ntawm qib 70, 80, 100, thiab 120 yog dab tsi?" Peb piav qhia qhov sib txawv ntawm cov pawg no thiab cov chains twg koj yuav tsum siv raws li koj xav tau.
Qib 70 Chain
Qib 70 saw yog tsim nyob rau hauv cov cua kub kho carbon steel. Kuj tseem hu ua "trucker's chain," tib neeg siv qib 70 raws li khi-downs ntawm txoj kev tsheb thauj mus los.Tsis txhob siv cov saw no rau kev nqa lub taub hau.
Hom no feem ntau nta kub chromate tiav kom nws yooj yim rau kev paub. Nws kuj ua tau raws li California Txoj Kev Loj Patrol thiab DOT cov cai. Kev siv rau cov saw hlau no, sib nrug ntawm kev thauj mus los, suav nrog kev thauj mus los, kev txiav, roj rigs, thiab kev siv kev nyab xeeb.
Cov saw no suav nrog cov qauv tsim embossed nrog 7, 70, lossis 700.
80 saw yog ib qho hluav taws kub kho steel saw nrog lub zog siab rau qhov hnyav piv. Nws lub zog ua rau nws muaj kev nyab xeeb rau kev nqa lub taub hau thiab nqa slings. Nws kuj yog qhov zoo heev rau kev siv xws li rov qab, kev nyab xeeb, thiab cov hlua txuas.
Cov saw no kuj tau dhau los ua ntau dua hauv kev lag luam flatbed tsheb thauj khoom kom ruaj ntseg cov khoom lag luam hnyav. Vim tias cov chains no feem ntau nruab nrog ib hom clevis rub nuv, thiab cov saw sib txuas no tsis pom zoo rau kev nqa nqa.
Cov saw no suav nrog cov qauv tsim embossed nrog 8, 80, lossis 800.
Qib 80 Chain
Qib 100 Chain
Qib 100 saw yog ib yam khoom tshiab thiab tau nrov zuj zus raws li kev hloov rau qib 80 saw. Pom zoo los ntawm cov tuam txhab tsim khoom, nws muab txog 25% kev ua haujlwm siab dua li qib 80 thiab ua haujlwm rau kev siv nyiaj siv ua haujlwm.
Ntau tus neeg siv qib 100 tshaj qib 80 kom ruaj ntseg cov khoom thauj. Cov saw no muaj lub zog ntxiv thiab qhov me me uas tsis tawm tsam qhov kev txwv kev ua haujlwm.
Txawm li cas los xij, vim tias cov saw hlau no feem ntau nruab nrog hom tshwj xeeb ntawm clevis rub nuv, thiab cov saw hlau sib txuas tsis tau pom zoo rau kev nqa nqa.
Cov saw no suav nrog cov qauv tsim embossed nrog 10, 100, lossis 1000.
Qib 120 saw tseem yog ib pawg tshiab ntawm cov saw hlau ua haujlwm siab, muab lub zog siab tshaj plaws hauv kev lag luam. Lub square txuas style tsim kev sib cuag ntau dua ntawm cov kabmob ntawm cov kab sib txuas, uas txo qis cov saw hlau.
Qhov no txhais tau hais tias qhov kev txwv tsis pub ua haujlwm yog 50% siab dua qib 80, thiab 20% siab dua qib 100. Chain qib 120 ua haujlwm rau kev nqa nyiaj siv ua haujlwm. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ib yam li Qib 80 khi cov hlua sib dhos thiab Qib 100 khi cov hlua sib dhos, cov hlua sib dhos kuj tsis muaj kev nyab xeeb rau kev nqa nyiaj siv ua haujlwm vim yog hom hooks siv.
Hom saw no muaj lub ci xiav ua tiav kom lawv pom tau yooj yim.
Qib 120 Chain
Txawm li cas los xij ntawm cov saw hlau, txhua tus yuav tsum ua raws li cov qauv tsim los ntawm National Association of Chain Manufacturers (NACM), uas suav nrog:
- Tsis txhob thauj lossis ncua kev thauj khoom hla tib neeg.
- Tshawb xyuas cov saw hlau ib ntus rau cov kab nrib pleb, gouges, hnav, elongation, nicks, thiab haum.
- Ntau qhov kub thiab txias los yog raug rau cov tshuaj lom neeg ib puag ncig xws li cov kua qaub lossis cov kua corrosive lossis pa taws tuaj yeem txo cov saw hlau ua haujlwm.
- Tham nrog cov saw hlau cov chaw tsim khoom yog tias cov saw hlau yuav ua haujlwm sab nraum qhov ntsuas kub tau pom zoo (-40 ° F txog 400 ° F).
- Tshem tawm cov saw hlau los ntawm kev pabcuam yog tias qhov tuab ntawm ib feem ntawm qhov txuas yog tsawg dua li teev tus nqi qis kawg nkaus.
- Thaum sib xyaw cov saw lossis cov khoom sib xyaw, txhua yam yuav tsum tau ntsuas ntawm kev ua haujlwm ntawm cov khoom siv qis tshaj plaws lossis cov saw hlau.
- Tshawb xyuas peb cov kev xaiv ntawm qib 70 thauj saw, nrog rau cov hlua khi.
