Cov saw hlau feem ntau yog siv los khi cov khoom thauj, rau kev nqa daim ntawv thov thiab rub cov khoom thauj - txawm li cas los xij, kev lag luam rigging cov qauv kev nyab xeeb tau tsim nyob rau xyoo tas los no, thiab cov saw siv rau kev nqa yuav tsum ua raws li qee qhov tshwj xeeb.
Chain slings yog ib qho ntawm cov kev xaiv nrov tshaj plaws los nqa lub nra, lawv feem ntau siv los nqa cov kab hluav taws xob, piv txwv li. Chain slings yog ruaj, ductile, muaj peev xwm tiv taus kub, rips & kua muag thiab nyob rau hauv tej yam kev siv, yog adjustable. tab sis koj yuav txiav txim siab li cas cov saw hlau zoo tshaj plaws rau koj qhov project xav tau?
Ob hom saw slings yog siv rau rigging thiab nqa daim ntaub ntawv - mechanical assembly thiab welded los ua ke. Chain slings yog tsim nrog qhov tsawg kawg nkaus kev nyab xeeb ntawm 4: 1.
Cov saw saw feem ntau siv hauv rigging thiab lifting yog mechanically assembled vim lawv tau ceev los tsim thiab nws tuaj yeem ua tiav nrog cov cuab yeej yooj yim. Chain slings yog tsim los ntawm ntau yam manufacturers thiab nyob rau hauv ntau yam configurations.
1. Mechanically Assembled Chain Sling Hardware
Tsim ib qho yooj yim mechanically assembled saw sling nrog cov khoom siv no:
● Master Link
● Mechanical Jointing Device (ie, txuas txuas)
● Shortening Clutch (yog tias xav tau)
● Round Link Chain
● Sling Hook (lwm yam haum raws li xav tau)
● Tag
2. Welded los ua ke
Welded saw slings tsis tshua siv. Lawv siv sijhawm ntau los tsim khoom, txij li thaum lawv tau ua lawv tau txais kev kho cua sov kom lawv muaj kev nyab xeeb siv hauv daim ntawv thov nqa. Qhov no yuav siv sij hawm hnub, piv rau cov feeb nws yuav siv sij hawm los ua ke ib tug mechanically assembled saw sling.
Tsim ib tug welded los ua ke saw sling nrog no hardware:
● Master Link
● Welded Intermediate Txuas
● Welded Txuas Txuas
● Cov saw
● Hook (lwm fittings yog tias xav tau)
● Tag
3. Yuav ua li cas los sib sau ib lub saw saw nrog cov qhab nia raug?
Cov qhab-nees rau chains raug lees paub los ntawm cov lej uas muaj nyob rau ntawm cov saw txuas. Cov qhab nia ntawm cov saw hlau sib dhos pib ntawm Qib 80 - Qib 80, 100 thiab 120 yog siv rau kev nqa daim ntawv thov. Tsis txhob siv qib 30, 40 lossis 70 chains rau kev nqa lub taub hau.
Cov qib no yog siv rau kev nqa raws li lawv nyob nraum ductile thiab tuaj yeem tiv nrog "kev poob siab" uas tuaj yeem tshwm sim thaum rigging.
4. Yuav ua li cas thiaj nrhiav tau txoj cai saws tes ua ke rau koj?
Ua raws li cov kauj ruam no los sib sau ua ke cov saw hlau zoo tshaj plaws rau koj cov kev xav tau nqa.
1. Txiav txim siab qhov hnyav ntawm lub thauj khoom nqa, nws ua haujlwm load txwv thiab txhua lub ces kaum uas yuav cuam tshuam rau lub nqa.
2. Lub taub hau mus rau qhov loj me / daim ntawv qhia tshwj xeeb muab los ntawm cov saw sling cov chaw tsim khoom. Nrhiav cov saw saw hlau configuration uas yuav haum koj load thiab nqa.
3. Lub taub hau mus rau daim ntawv sib dhos pom nyob hauv phau ntawv teev npe lossis lub vev xaib ntawm koj tus neeg faib khoom. Nrhiav Kev Ua Haujlwm Load Limit (WLL) txhawm rau nqa rau saum toj ntawm daim ntawv. Nrhiav kab uas sawv cev rau qhov loj / ntev, uas yuav muab pub rau hauv centimeters, nti lossis millimeters. Nco ntsoov kom loj.Piv txwv:Yog tias koj qhov load WLL yog 3,000lbs daim ntawv yuav muab rau koj ob txoj kev xaiv - WLL ntawm 2,650 thiab 4,500. Xaiv cov saw ntev uas sib haum nrog WLL ntawm 4,500lbs - nws yog qhov zoo dua kom muaj peev xwm ntau dhau tsis txaus.
4. Siv tib cov lus qhia los ntawm Kauj Ruam 3 los xaiv cov khoom siv kho vajtse / fittings los ntawm cov ntawv qhia tshwj xeeb.Piv txwv:Koj tau xaiv DOG sling configuration - qhov no txhais tau tias koj yuav tsum nrhiav ib tug oblong zoo li tus tswv txuas thiab ib tug rub nuv uas sib xws rau WLL.
Piv txwv li: Bob tab tom npaj nqa ib lub nra nrog WLL ntawm 3,000lbs thiab xav sib sau ua ke cov hlua hlua.
Kauj ruam 1)Bob pom WLL kem ntawm nws lub khw muag khoom.
Kauj ruam 2)Nrhiav WLL - txij li 3,000lbs tsis nyob rau hauv daim ntawv, peb xaiv tus tom ntej uas muaj WLL ntawm 4,500lbs.
Kauj ruam 3)Bob xav tau saw nrog 1.79in. ntev.
