Cov saw hlau feem ntau siv los khi cov khoom thauj, rau kev nqa cov ntawv thov thiab rub cov khoom thauj - txawm li cas los xij, cov qauv kev nyab xeeb ntawm kev lag luam rigging tau tsim kho nyob rau xyoo tas los no, thiab cov saw hlau siv rau kev nqa yuav tsum ua tau raws li qee qhov kev qhia tshwj xeeb.
Cov saw hlau yog cov kev xaiv nrov tshaj plaws los tsa cov khoom thauj, lawv feem ntau siv los tsa cov kab sib kis, piv txwv li. Cov saw hlau yog cov ruaj khov, ductile, tuaj yeem tiv taus qhov kub siab, rips & kua muag thiab hauv qee qhov kev siv, tuaj yeem hloov kho tau. tab sis koj yuav txiav txim siab li cas qhov saw hlau zoo tshaj plaws rau koj qhov project xav tau?
Ob hom saw hlau siv rau kev rigging thiab kev siv lifting - mechanical assembly thiab welded assembly. Cov saw hlau yog ua nrog qhov tsawg kawg nkaus kev nyab xeeb ntawm 4: 1.
Cov saw hlau uas siv ntau tshaj plaws hauv kev rigging thiab kev tsa yog kev sib dhos ua ke vim tias lawv ua tau sai thiab nws tuaj yeem ua tiav nrog cov cuab yeej yooj yim. Cov saw hlau yog ua los ntawm ntau lub tuam txhab tsim khoom thiab muaj ntau yam kev teeb tsa sib txawv.
1. Cov Khoom Siv Kho Vajtse Uas Sib Dhos Ua Ke
Tsim ib lub tshuab sib dhos yooj yim nrog cov khoom siv no:
● Qhov Txuas Tseem Ceeb
● Cov Khoom Siv Sib Koom Tes (piv txwv li, txuas txuas)
● Lub Clutch Luv (yog tias xav tau)
● Cov saw hlau sib txuas
● Sling Hook (lwm yam khoom siv raws li xav tau)
● Cim npe
2. Kev Sib Dhos Welded
Cov saw hlau uas vuam tsis tshua muaj neeg siv. Lawv siv sijhawm ntau dua los tsim, vim tias thaum lawv ua tiav lawm lawv yuav raug kho cua sov kom lawv muaj kev nyab xeeb siv rau hauv daim ntawv thov nqa. Qhov no siv sijhawm ntau hnub, piv rau feeb uas nws siv los ua ke ib lub saw hlau uas sib dhos ua ke.
Tsim ib lub welded sib dhos saw hlau nrog cov khoom siv no:
● Qhov Txuas Tseem Ceeb
● Txuas Nruab Nrab Welded
● Txuas Txuas Welded
● Saw
● Qhov (lwm yam khoom siv yog tias xav tau)
● Cim npe
3. Yuav Ua Li Cas Sib Dhos Ib Lub Saw Hlau Nrog Cov Qib Saw Hlau Kom Yog?
Cov qib cim rau cov saw hlau yog lees paub los ntawm cov lej uas pom ntawm cov saw hlau txuas. Cov qib saw hlau rau kev sib dhos saw hlau pib ntawm Qib 80 - Qib 80, 100 thiab 120 yog siv rau kev siv nqa. Tsis txhob siv cov saw hlau qib 30, 40 lossis 70 rau kev nqa saum taub hau.
Cov qib no yog siv rau kev tsa vim lawv yog ductile thiab tuaj yeem tiv taus "kev thauj khoom poob siab" uas tuaj yeem tshwm sim thaum rigging.
4. Yuav ua li cas thiaj nrhiav tau lub Rooj Sib Tham Sling uas yog rau koj?
Ua raws li cov kauj ruam no kom sib sau ua ke cov saw hlau zoo tshaj plaws rau koj cov kev xav tau nqa.
1. Txheeb xyuas qhov hnyav ntawm lub nra uas yuav tsum nqa, nws qhov kev txwv ntawm kev ua haujlwm thiab txhua lub kaum sab xis uas yuav cuam tshuam rau kev nqa.
2. Mus saib daim ntawv qhia qhov loj/cov lus qhia uas lub chaw tsim khoom siv saw hlau muab. Nrhiav qhov kev teeb tsa ntawm saw hlau uas yuav haum rau koj qhov hnyav thiab nqa.
3. Mus rau daim ntawv qhia sib dhos uas pom hauv phau ntawv teev khoom lossis lub vev xaib ntawm koj tus neeg faib khoom. Nrhiav Qhov Kev Txwv Kev Thauj Khoom Ua Haujlwm (WLL) kom tsa tau rau saum daim ntawv qhia. Nrhiav kab uas sawv cev rau qhov loj/ntev, uas yuav raug pub dawb hauv centimeters, nti lossis millimetres. Nco ntsoov ua kom loj dua.Piv txwv li:Yog tias koj lub nra hnyav WLL yog 3,000lbs daim ntawv qhia yuav muab ob txoj kev xaiv rau koj - WLL ntawm 2,650 thiab 4,500. Xaiv qhov ntev ntawm cov saw hlau uas sib xws nrog WLL ntawm 4,500lbs - nws zoo dua kom muaj peev xwm ntau dhau dua li tsis txaus.
4. Siv cov lus qhia tib yam los ntawm Kauj Ruam 3 los xaiv cov khoom siv kho vajtse / cov khoom siv los ntawm daim ntawv qhia tshwj xeeb.Piv txwv li:Koj tau xaiv qhov kev teeb tsa DOG sling - qhov no txhais tau tias koj yuav tsum nrhiav qhov txuas tswv zoo li oblong thiab lub nuv tuav uas sib xws rau WLL.
Piv txwv li: Bob tab tom npaj yuav tsa ib lub nra hnyav nrog WLL ntawm 3,000lbs thiab xav sib sau ua ke ib txoj saw hlau.
Kauj Ruam 1)Bob pom cov kab WLL ntawm nws tus khw muag khoom.
Kauj Ruam 2)Nrhiav qhov WLL - vim tias 3,000lbs tsis nyob hauv daim ntawv qhia, peb xaiv qhov tom ntej uas muaj WLL ntawm 4,500lbs.
Kauj Ruam 3)Bob xav tau txoj saw uas ntev 1.79 nti.
