Thauj chains(tseem hu ua lashing chains, khi-down chains, los yog binding chains) yog lub zog siab alloy steel chains siv los ua kom ruaj khov hnyav, tsis xwm yeem, lossis cov khoom muaj nqi siab thaum lub caij tsheb thauj mus los. Ua ke nrog cov khoom siv xws li binders, hooks, thiab shackles, lawv tsim cov txheej txheem tseem ceeb uas tiv thaiv cov khoom thauj, kev puas tsuaj, thiab kev sib tsoo.
Cov ntawv thov tseem ceeb yog:
- Kev ruaj ntseg kev tsim kho / khoom hnyav (excavators, bulldozers)
- Stabilizing steel coils, structural beams, thiab cov kav dej ua vaj tse
- Thauj machinery, industrial modules, los yog oversized loads
- Cov chaw muaj kev pheej hmoo siab (nruj npoo, hnyav hnyav, kub / sib txhuam)
Qhov tseem ceeb ntawm deploying thauj chains:
- Kev nyab xeeb:Tiv thaiv kev hloov pauv uas tuaj yeem ua rau rollovers lossis jackknifes.
- Ua raws li:Ua tau raws li cov qauv kev cai lij choj (xws li FMCSA hauv Asmeskas, EN 12195-3 hauv EU).
- Kev tiv thaiv khoom vaj khoom tsev:Minimizes kev puas tsuaj rau cov khoom thauj / tsheb thauj khoom.
- Nqi Efficiency:Reusable thiab kav ntev yog khaws cia kom zoo.
Nov yog cov lus qhia dav dav rau kev thauj mus los / lashing chains rau tsheb thauj khoom ruaj ntseg, hais txog qee cov ntsiab lus tshwj xeeb zoo los ntawm kev lag luam:
| Feature | Thauj Chains | Webbing Slings |
|---|---|---|
| Khoom siv | Alloy steel (Qib G70, G80, G100) | Polyester / nylon webbing |
| Zoo tshaj rau | Nthuav-edged loads, hnyav hnyav (> 10T), kev sib txhuam / puas, siab kub | Qhov chaw mos, lub teeb yuag cargo, |
| Lub zog | Ultra-siab WLL (20,000+ lbs), tsawg kawg stretch | WLL (txog 15,000 lbs), me ntsis elasticity |
| Kev puas tsuaj kuj | Resistant txiav, abrasion, UV degradation | Yooj yim rau kev txiav, tshuaj lom neeg, UV ploj |
| Ib puag ncig | ntub, oily, kub, los yog abrasive tej yam kev mob | Qhuav, tswj ib puag ncig |
| Siv dav | Steel coils, siv machinery, hnyav structural steel | Rooj tog, iav, pleev xim rau saum npoo |
Qhov txawv tseem ceeb:Chains excel rau hnyav, abrasive, los yog ntse loads qhov twg durability yog ib qho tseem ceeb; webbing tiv thaiv cov khoom tawg yooj yim thiab sib dua / yooj yim los tuav.
A. Txoj Kev Xaiv
1. Qib Kawm:
-G70 (Kev Thauj Mus Los): Kev siv dav dav, zoo ductility.
-G80 (Lifting Chain):Lub zog siab dua, feem ntau rau kev ruaj ntseg.
-G100:Siab tshaj zog-rau-qhov hnyav piv (siv nrog cov khoom siv sib xws).
- Ib txwm phim cov qib saw rau qib kho vajtse.
2. Loj & WLL:
- Txheeb xyuas tag nrho cov kev xav tau nruj (ib cov kev cai xws li EN 12195-3 lossis FMCSA).
- Piv txwv: 20,000 lb load xav tau ≥5,000 lbs nro ib saw (4: 1 kev nyab xeeb yam).
- Siv chains nrog WLL ≥ xam nro (piv txwv li, 5/16 "G80 saw: WLL 4,700 lbs).
B. Kev xaiv kho vajtse
- Binders:
Ratchet Binders: Precise nro, ruaj ntseg tuav (zoo tagnrho rau cov khoom tseem ceeb).
Lever Binders: nrawm dua, tab sis kev pheej hmoo ntawm snap-rov qab (yuav tsum tau kawm).
- Hooks / Attachments:
Grab Hooks: Txuas rau cov hlua txuas.
Slip Hooks: Thauj tog rau nkoj rau cov ntsiab lus tas (piv txwv li, tsheb ncej).
C-Hooks / Clevis Links: Rau cov khoom tshwj xeeb (piv txwv li, steel coil ob lub qhov muag).
- Accessories: Edge protectors, nro saib, shackles.
C. Load-Specific Configurations
- Siv Machinery (piv txwv li, Excavator):G80 chains (3/8 "+) nrog ratchet binders;Ruaj ntseg lem / log + cov ntsiab lus txuas; tiv thaiv articulation txav.
- Steel Coils:G100 chains nrog C-hooks lossis chocks;Siv "daim duab-8" threading los ntawm coil qhov muag.
-Structure Beams:G70 / G80 chains nrog ntoo dunnage los tiv thaiv zawv zawg;Hla-chain ntawm cov ces kaum ≥45 ° rau lateral stability.
- Cov kav dej pob zeb: Chock kawg + chains hla cov yeeb nkab ntawm 30 ° -60 ° cov ces kaum.
A. Kev tshuaj xyuas (ua ntej / tom qab siv txhua)
- Chain Links:Tsis lees paub yog: Stretched ≥3% ntawm qhov ntev, kab nrib pleb, nicks> 10% ntawm txoj kab uas hla, weld splatter, hnyav corrosion.
- Hooks/Shackles:Tsis lees paub yog: Twisted, caj pas qhib> 15% nce, tawg, tsis muaj kev ruaj ntseg latches.
- Binders:Tsis lees paub yog: Khoov kov / lub cev, hnav pawls / iav, xoob bolts, xeb hauv ratchet mechanism.
- General:Txheeb xyuas qhov hnav ntawm cov ntsiab lus tiv tauj (piv txwv li, qhov twg cov saw hlau kov cov khoom);Txheeb xyuas WLL cov cim thiab cov ntawv qib.
B. Cov Lus Qhia Hloov
- Yuav Tsum Tau Hloov:Txhua qhov pom cov kab nrib pleb, elongation, lossis qib stamp tsis pom zoo;Hooks / shackles khoov> 10 ° los ntawm cov duab qub;Chain txuas hnav> 15% ntawm thawj txoj kab uas hla.
- Kev Tiv Thaiv Kev Tiv Thaiv:Lubricate ratchet binders txhua hli;Hloov cov binders txhua txhua 3-5 xyoos (txawm tias tsis zoo; sab hauv tsis pom);Cov hlua khi tawm tom qab 5-7 xyoo ntawm kev siv hnyav (cov ntaub ntawv tshuaj xyuas).
C. Cov ntaub ntawv
- Khaws cov ntaub ntawv nrog cov hnub tim, lub npe tshuaj ntsuam xyuas, kev tshawb pom, thiab kev nqis tes ua.
- Ua raws li cov qauv: ASME B30.9 (Slings), OSHA 1910.184, EN 12195-3
