Cov saw hlau thauj mus los(tseem hu ua cov saw hlau khi, cov saw hlau khi, lossis cov saw hlau khi) yog cov saw hlau ua los ntawm cov hlau sib xyaw ua ke uas muaj zog heev siv los khi cov khoom hnyav, tsis sib xws, lossis muaj nqis heev thaum lub sijhawm thauj mus los ntawm txoj kev. Ua ke nrog cov khoom siv xws li cov hlua khi, cov hooks, thiab cov shackles, lawv tsim ib lub kaw lus tseem ceeb uas tiv thaiv kev thauj khoom, kev puas tsuaj, thiab kev sib tsoo.
Cov Kev Siv Tseem Ceeb yog:
- Kev ruaj ntseg rau kev tsim kho / cov khoom siv hnyav (excavators, bulldozers)
- Kev ruaj khov ntawm cov hlau kauj, cov nqaj hlau, thiab cov kav dej ua los ntawm pob zeb
- Kev thauj cov tshuab, cov khoom siv hauv kev lag luam, lossis cov khoom loj heev
- Ib puag ncig muaj kev pheej hmoo siab (ntug ntse, qhov hnyav heev, kub/kev sib txhuam)
Qhov tseem ceeb ntawm kev xa cov saw hlau thauj mus los:
- Kev Nyab Xeeb:Tiv thaiv kev hloov pauv ntawm lub nra uas yuav ua rau rollovers lossis jackknives.
- Kev Ua Raws Cai:Ua tau raws li cov qauv kev cai lij choj (piv txwv li, FMCSA hauv Tebchaws Meskas, EN 12195-3 hauv EU).
- Kev Tiv Thaiv Cov Khoom Muaj Nqis:Txo qhov kev puas tsuaj rau cov khoom thauj / tsheb thauj khoom.
- Kev Siv Nyiaj Zoo:Siv tau dua thiab siv tau ntev yog tias khaws cia kom zoo.
Nov yog phau ntawv qhia txog kev thauj mus los/kev khi hlua khi rau kev ruaj ntseg khoom thauj, hais txog qee cov ntsiab lus tshwj xeeb uas cov lag luam xav txog:
| Feature | Cov Kev Thauj Mus Los | Cov Webbing Slings |
|---|---|---|
| Khoom siv | Cov hlau sib xyaw (Qib G70, G80, G100) | Cov ntaub polyester/nylon |
| Zoo Tshaj Plaws Rau | Cov khoom thauj ntse ntse, qhov hnyav hnyav heev (> 10T), kev sib txhuam/kev txhuam siab, cua sov siab | Cov nto mos mos, cov khoom thauj khoom tsis hnyav, |
| Lub zog | WLL siab heev (20,000+ lbs), ncab tsawg kawg nkaus | WLL (txog li 15,000 lbs), me ntsis elasticity |
| Kev Tiv Thaiv Kev Puas Tsuaj | Tiv taus kev txiav, kev puas tsuaj, kev puas tsuaj UV | Muaj kev phom sij rau kev txiav, tshuaj lom neeg, UV ploj |
| Ib puag ncig | Cov xwm txheej ntub dej, roj, kub, lossis txhuam | Qhov chaw qhuav, tswj tau |
| Cov Kev Siv Feem Ntau | Cov hlau kauj, cov tshuab siv hauv kev tsim kho, cov hlau hnyav | Rooj tog, iav, cov chaw pleev xim |
Qhov Txawv Tseem Ceeb:Cov saw hlau zoo heev rau cov khoom hnyav, abrasive, lossis cov khoom ntse uas qhov kev ruaj khov yog qhov tseem ceeb; webbing tiv thaiv cov chaw tsis yooj yim thiab sib dua / yooj yim dua rau kev tuav.
A. Kev Xaiv Saw
1. Qib Kawm Tseem Ceeb:
-G70 (Kev Thauj Mus Los Saw): Siv dav dav, zoo ductility.
-G80 (Saw Nqa):Muaj zog dua, feem ntau rau kev ruaj ntseg.
-G100:Qhov sib piv ntawm lub zog thiab qhov hnyav siab tshaj plaws (siv nrog cov khoom siv sib xws).
- Ib txwm phim qib saw hlau rau qib kho vajtse.
2. Loj & WLL:
- Xam tag nrho cov kev ntxhov siab uas xav tau (raws li cov cai xws li EN 12195-3 lossis FMCSA).
- Piv txwv li: 20,000 lb load xav tau ≥5,000 lbs tension ib saw (4:1 safety factor).
- Siv cov saw hlau uas muaj WLL ≥ qhov nro uas tau xam (piv txwv li, 5/16" G80 saw hlau: WLL 4,700 lbs).
B. Kev Xaiv Khoom Siv Kho Vaj Tse
- Cov ntawv khi:
Cov Ratchet Binders: Kev nruj kom raug, kev tuav pov hwm zoo dua (zoo tagnrho rau cov khoom hnyav).
Cov Qiv Qiv: Sai dua, tab sis muaj kev pheej hmoo ntawm kev rov qab (yuav tsum tau kev cob qhia).
- Cov Hooks / Cov Khoom Txuas:
Cov Hooks: Txuas rau cov saw hlau.
Cov Hooks Slip: Anchor rau cov ntsiab lus ruaj khov (piv txwv li, lub thav duab tsheb thauj khoom).
Cov C-Hooks/Clevis Links: Rau cov khoom siv tshwj xeeb (piv txwv li, qhov muag hlau).
- Cov Khoom Siv: Cov cuab yeej tiv thaiv ntug, cov cuab yeej saib xyuas kev nruj, cov hlua khi.
C. Kev Teeb tsa Tshwj Xeeb rau Qhov Chaw Thauj Khoom
- Cov Tshuab Siv Hauv Tsev (piv txwv li, Excavator):G80 saw hlau (3/8 "+) nrog ratchet binders;Ruaj ntseg cov kev sib txuas/log + cov ntsiab lus txuas; tiv thaiv kev txav mus los.
- Cov Hlau Coils:G100 saw hlau nrog C-hooks lossis chocks;Siv cov xov "duab-8" los ntawm lub qhov muag coil.
- Cov Ncej Qauv:G70/G80 saw hlau nrog cov ntoo dunnage kom tiv thaiv kev swb;Cov saw hlau hla ntawm cov ces kaum ≥45 ° rau kev ruaj khov sab.
- Cov Kav Dej Ua Los Ntawm Pob Zeb: Cov kawg ntawm cov kav dej + cov saw hlau hla cov kav dej ntawm lub kaum sab xis 30 ° -60 °.
A. Kev Tshuaj Xyuas (Ua Ntej/Tom Qab Txhua Lub Sijhawm Siv)
- Cov Txuas Saw:Tsis lees txais yog tias: Ncab ≥3% ntawm qhov ntev, tawg, nicks >10% ntawm qhov txuas txoj kab uas hla, weld splatter, xeb hnyav.
- Cov Hooks/Shackles:Tsis lees txais yog tias: Ntswj, qhov qhib caj pas >15% nce, tawg, ploj lawm cov xauv kev nyab xeeb.
- Cov ntawv khi:Tsis lees txais yog tias: Lub tes tuav/lub cev khoov, cov pawls/gears hnav lawm, cov bolts xoob, xeb hauv lub ratchet mechanism.
- Dav Dav:Xyuas seb puas muaj kev hnav ntawm cov chaw sib cuag (piv txwv li, qhov chaw uas cov saw hlau kov cov khoom thauj);Xyuas kom meej cov cim WLL thiab cov ntawv cim qib uas nyeem tau yooj yim.
B. Cov Lus Qhia Txog Kev Hloov
- Yuav tsum tau hloov pauv:Tej qhov tawg uas pom tau, elongation, lossis grade stamp uas nyeem tsis tau;Cov Hooks/shackles khoov > 10° ntawm daim duab qub;Kev hnav ntawm cov saw hlau txuas >15% ntawm lub cheeb thawj.
- Kev Txij Nkawm Tiv Thaiv:Siv roj nplua nyeem rau cov ratchet binders txhua hli;Hloov cov ntawv khi txhua 3-5 xyoos (txawm tias tseem zoo los xij; sab hauv tsis pom kev puas tsuaj);Tshem tawm cov saw hlau tom qab 5-7 xyoo ntawm kev siv ntau (kev tshuaj xyuas cov ntaub ntawv).
C. Cov Ntaub Ntawv
- Khaws cov ntaub ntawv teev cia nrog hnub tim, lub npe ntawm tus neeg tshuaj xyuas, cov ntaub ntawv pom, thiab cov haujlwm tau ua.
- Ua raws li cov qauv: ASME B30.9 (Slings), OSHA 1910.184, EN 12195-3
