Cheni dzekutakura(anonziwo lashing chain, tie-down cheins, or binding cheni) ndiwo macheni esimbi ane simba guru anoshandiswa kuchengetedza zvinhu zvinorema, zvisina kujairika, kana kuti zvakakosha panguva yekufambisa mumugwagwa. Yakapetwa nehardware senge mabhainda, zvikorekedzo, uye macheni, ivo vanogadzira yakakomba mitoro inodzivirira inodzivirira kufamba kwekutakura, kukuvara, uye tsaona.
Zvikumbiro zvekutanga ndezvekuti:
-Kuchengetedza kuvaka / inorema michina (vacheri, mabulldozer)
- Kudzikamisa simbi koiri, matanda ezvimiro, uye pombi dzekongiri
-Kutakura michina, maindasitiri modules, kana mitoro yakawandisa
-Nzvimbo dzine njodzi huru (mipendero yakapinza, uremu hwakanyanya, kupisa / kupokana)
Kukosha kwekuisa cheni dzekutakura:
- Chengetedzo:Inodzivirira kusimuka kwekutakura kunogona kukonzera rollover kana jackknifes.
- Kutevedzera:Inosangana nezviyero zvemutemo (semuenzaniso, FMCSA muUSA, EN 12195-3 muEU).
- Dziviriro yeAsset:Inoderedza kukuvadzwa kwemutoro / marori.
- Kushanda Kwemari:Reusable uye inogara kwenguva refu kana ikachengetwa nemazvo.
Heino gwara rakazara rekutakura / lashing cheni yekuchengetedza kutakura zvinhu zverori, kugadzirisa mamwe mapoinzi akatariswa nemaindasitiri:
| Feature | Zvekutakura Cheni | Webbing Slings |
|---|---|---|
| Material | Alloy simbi (Makirasi G70, G80, G100) | Polyester/nylon webbing |
| Best For | Mitoro yakapinza-yakapinza, uremu hwakanyanyisa (> 10T), kukwesha kukuru/kupwanya, kupisa kwakanyanya. | Delicate surface, lightweight cargo, |
| Simba | Ultra-yakakwirira WLL (20,000+ lbs), yakatambanudzwa zvishoma | WLL (kusvika ku15,000 lbs), zvishoma elasticity |
| Kukuvadza Kupikisa | Inoramba kuchekwa, abrasion, kusvibiswa kweUV | Ari panjodzi yekuchekwa, makemikari, UV kupera |
| Environment | Manyoro, ane mafuta, anopisa, kana abrasive mamiriro | Dry, controlled environments |
| Common Use | Simbi coils, kuvaka muchina, inorema structural simbi | Furnicha, girazi, pendi nzvimbo |
Musiyano Wakakosha:Maketani anokunda kune inorema, abrasive, kana inopinza mitoro uko kusimba kwakakosha; webbing inodzivirira nzvimbo isina kusimba uye inoreruka/nyore kubata.
A. Chain Selection
1. Grade Matters:
-G70 (Transport Chain): General kushandiswa, zvakanaka ductility.
-G80 (Kusimudza Chain):Kusimba kwepamusoro, kwakajairika pakuchengetedza.
-G100:Yepamusoro-simba-ku-huremu reshiyo (shandisa nehardware inoenderana).
-Gara uchifananidza cheni giredhi kune Hardware giredhi.
2. Saizi & WLL:
- Verenga yakazara inodiwa tension (pamirau senge EN 12195-3 kana FMCSA).
- Muenzaniso: 20,000 lb load inoda ≥5,000 lbs tension per chain (4: 1 kuchengetedza chinhu).
- Shandisa cheni neWLL ≥ yakaverengerwa tension (semuenzaniso, 5/16" G80 cheni: WLL 4,700 lbs).
B. Hardware Selection
- Binders:
Ratchet Binders: Chaiyo tension, yakachengeteka kubata (yakanakira mitoro yakaoma).
Lever Binders: Inokurumidza, asi njodzi ye snap-back (inoda kudzidziswa).
- Hooks/Attachments:
Bata Hooks: Batanidza kumaketani zvinongedzo.
Slip Hooks: Anchor kune yakatarwa mapoinzi (semuenzaniso, rori furemu).
C-Hooks/Clevis Links: Zvekunamirwa zvakanamirwa (semuenzaniso, simbi coil maziso).
- Zvishandiso: Edge vadziviriri, tension monitors, maketani.
C. Rodha-Yakananga Magadzirirwo
-Kuvaka Michina (semuenzaniso, Excavator):G80 cheni (3/8"+) ine ratchet binders;Chengetedza mateki / mavhiri + mapoinzi ekunamatira; kudzivirira kufamba kwekutaura.
-Simbi Coils:G100 maketani ane C-hook kana chocks;Shandisa "figure-8" threading kuburikidza necoil ziso.
- Structural Beams:G70/G80 maketani ane matanda dunnage kudzivirira kutsvedza;Muchinjikwa-cheni pamakona ≥45 ° yekugadzikana kwe lateral.
- Concrete Mapaipi: Chock inoguma + cheni pamusoro pepombi pa30 ° -60 ° angles.
A. Kuongorora (Pamberi/Pashure Pekushandisa Kwese)
- Chain Links:Ramba kana: Yakatambanudzwa ≥3% yehurefu, kuputika, nicks > 10% yehupamhi hwekubatanidza, weld splatter, kuparara kwakanyanya.
- Hook / Shackles:Ramba kana: Yakamonyoroka, kuvhurwa kwehuro> 15% kuwedzera, kutsemuka, kushaikwa kwekuchengetedza machira.
- Binders:Ramba kana: Mubato wakabhenda/muviri, pawls/giya dzakasakara, mabhaudhi asina kusimba, ngura mumagetsi eratchet.
- General:Tarisa kupfekwa panzvimbo dzekusangana (semuenzaniso, uko cheni inobata mutoro);Wona zvitambi zveWLL zvinotendeseka uye zvitambi zvegiredhi.
B. Replacement Guidelines
- Inosungirwa Kutsiva:Chero makatsemuka, kurebesa, kana giredhi zvitambi zvisingaverengeke;Hoko/maketani akakotama>10° kubva pachimiro chepakutanga;Chain link inopfeka> 15% yedhayamita yekutanga.
- Preventative Maintenance:Lubricate ratchet binders pamwedzi;Tsiva mabhainda ega ega makore 3-5 (kunyangwe kana akasimba; kupfeka kwemukati hakuoneki);Retire cheni mushure memakore 5-7 ekushandiswa kwakanyanya (zvinyorwa zvekuongorora).
C. Zvinyorwa
-Chengetedza matanda ane misi, zita remuongorori, zvakawanikwa, uye zviito zvakatorwa.
- Tevera zviyero: ASME B30.9 (Slings), OSHA 1910.184, EN 12195-3
