Imixokelelwane yezothutho(ekwabizwa ngokuba ngamatyathanga aqhagamshelweyo, amatyathanga okubopha, okanye amatyathanga okubopha) ngamatyathanga esinyithi anamandla aphezulu asetyenziselwa ukukhusela imithwalo enzima, engaqhelekanga, okanye enexabiso eliphezulu ngexesha lokuthuthwa kwendlela. Zidityaniswe nehardware efana nezibophelelo, iigwegwe, kunye namakhamandela, zenza inkqubo ebalulekileyo yokuthintela umthwalo ethintela ukutshintshwa kwempahla, umonakalo, kunye neengozi.
Izicelo eziphambili zezi:
- Ukukhusela izixhobo zokwakha/ezinzima (abagrumbi, iibulldozers)
- Ukuzinzisa iikhoyili zentsimbi, imiqadi yesakhiwo, kunye nemibhobho yekhonkrithi
- Oomatshini bokuthuthwa, iimodyuli zamashishini, okanye imithwalo enzima kakhulu
-Iindawo ezinomngcipheko ophezulu (imiphetho ebukhali, ubunzima obugqithisileyo, ubushushu/ingxabano)
Ukubaluleka kokuthumela amakhonkco othutho:
- Ukhuseleko:Inqanda ukutshintshwa komthwalo okunokubangela ii-rollovers okanye ii-jackknifes.
-Ukuthobela:Idibana nemigangatho yomthetho (umzekelo, i-FMCSA e-USA, i-EN 12195-3 kwi-EU).
- Ukhuseleko lweAsethi:Yehlisa umonakalo kwimpahla/iilori.
- Ukusebenza kakuhle kweendleko:Isebenziseka kwakhona kwaye ihlala ixesha elide ukuba igcinwe ngokufanelekileyo.
Nasi isikhokelo esibanzi sothutho/amatyathanga okubotshelelwa kukhuseleko lomthwalo welori, sijongana neendawo ezithile eziqwalaselwa kakuhle yimizi-mveliso:
| Uphawu | Imixokelelwane yezoThutho | Izilingi zeWebhu |
|---|---|---|
| Izinto eziphathekayo | Intsimbi yentsimbi (amaBanga G70, G80, G100) | Ipolyester/nayiloni iwebhing |
| Engcono Kwi | Imithwalo ebukhali, ubunzima obugqithisileyo (> 10T), ukukhuhlana okuphezulu / ukukrazula, ubushushu obuphezulu | Umphezulu obuthathaka, imithwalo elula, |
| Amandla | I-WLL ephezulu kakhulu (i-20,000+ lbs), ukulula okuncinci | I-WLL (ukuya kwi-15,000 lbs), i-elasticity encinci |
| Ukumelana nomonakalo | Ixhathisa ukusikwa, ukonakala, ukuthotywa kwe-UV | Usengozini yokusikwa, iikhemikhali, i-UV fade |
| Okusingqongileyo | Iimeko ezimanzi, ezinamafutha, ezishushu, okanye ezirhabaxa | Imimandla eyomileyo, elawulwayo |
| Ukusetyenziswa okuqhelekileyo | Iikhoyili zentsimbi, oomatshini bokwakha, intsimbi enzima yesakhiwo | Ifenitshala, iglasi, iindawo ezipeyintiweyo |
Umahluko oPhambili:Amatyathanga agqwesa kwimithwalo enzima, erhabaxa, okanye ebukhali apho ukuqina kubaluleke kakhulu; iwebhu ikhusela umphezulu oethe-ethe kwaye ikhaphukhaphu/ilula ukuyiphatha.
A. UKhetho lwekhonkco
1. Imiba yeBanga:
-I-G70 (Ikhonkco lezoThutho): Ukusetyenziswa ngokubanzi, i-ductility elungileyo.
-G80 (Lifting Chain):Amandla aphezulu, aqhelekileyo ukhuseleko.
-G100:Umlinganiselo ophezulu wamandla-to-ubunzima (sebenzisa nge-hardware ehambelanayo).
- Soloko utshatisa ibakala lekhonkco kunye nenqanaba lehardware.
2. Ubungakanani & WLL:
- Bala uxinezeleko olufunekayo (ngokwemimiselo efana ne-EN 12195-3 okanye i-FMCSA).
- Umzekelo: I-20,000 lb idinga umthwalo ≥5,000 lbs ukunyanzeliswa kwekhonkco nganye (4: 1 factor factor).
- Sebenzisa amatyathanga nge-WLL ≥ i-tension ebalwayo (umzekelo, i-5/16" i-G80 chain: WLL 4,700 lbs).
B. Ukukhetha izixhobo
- Izibophelelo:
I-Ratchet Binders: Uxinzelelo oluchanekileyo, ukuphatha ngokukhuselekileyo (kufanelekile kwimithwalo ebalulekileyo).
I-Lever Binders: Ngokukhawuleza, kodwa umngcipheko we-snap-back (udinga uqeqesho).
-Amagwegwe/Iziqhoboshelo:
Bamba iiHooks: Qhagamshela kwikhonkco zamakhonkco.
I-Slip Hooks: I-ankile kwiindawo ezizinzileyo (umzekelo, isakhelo selori).
I-C-Hooks/Clevis Links: Kwizihlomelo ezikhethekileyo (umzekelo, amehlo e-coil yensimbi).
-Izincedisi: Izikhuseli zomda, iimonitha zoxinzelelo, amakhamandela.
C. Ulungelelwaniso oluKhethekileyo lomthwalo
- Oomatshini bokwakha (umzekelo, i-Excavator):Amatyathanga e-G80 (3/8"+) anezibophelelo zeratchet;Iingoma ezikhuselekileyo / amavili + amanqaku okuncamathisela; ukuthintela intshukumo yokuthetha.
- Iikhoyili zentsimbi:Amakhonkco e-G100 ane-C-hooks okanye ii-chocks;Sebenzisa "umzobo-8" ukuthunga ngeso lekhoyili.
- Imiqadi yoLwakhiwo:Amatyathanga e-G70/G80 anenkunkuma yamaplanga ukuthintela ukutyibilika;I-Cross-chain kwii-angles ≥45 ° ukuzinza kwecala.
- Imibhobho yeConcrete: Chock ends + chains over pipe at 30 ° -60 ° angles.
A. Uhlolo (Phambi/emva kokusetyenziswa ngakunye)
- Iikhonkco zekhonkco:Yala ukuba: Yoluliwe ≥3% yobude, iintanda, iziqhulo> 10% ye-diameter yekhonkco, i-weld splatter, i-corrosion enzima.
-Amagwegwe/Amakhamandela:Yala ukuba: Ujijekile, ukuvulwa komqala > ukwanda kwe-15%, iintanda, iintambo zokhuseleko ezingekhoyo.
- Izibophelelo:Yala ukuba: Umqheba ogobileyo/umzimba, iipawls/iigiya ezigugileyo, iibholiti ezikhululekileyo, umhlwa kwisixhobo seratchet.
- Ngokubanzi:Khangela ukuguga kwiindawo zoqhagamshelwano (umz., apho ikhonkco lichukumisa umthwalo);Qinisekisa iimpawu ezifundekayo zeWLL kunye nezitampu zebakala.
B. Izikhokelo zoTshintsho
- Ukutshintshwa okunyanzelekileyo:Naziphi na iintanda ezibonakalayo, ubude, okanye isitampu sebakala esingafundekiyo;amagwegwe/amakhamandela agotywe>10° ukusuka kwimilo yoqobo;Ikhonkco lekhonkco linxiba> i-15% yobukhulu bokuqala.
- ULondolozo loThintelo:Lubricate ratchet binders ngenyanga;Shintsha izibophelelo rhoqo emva kweminyaka emi-3 ukuya kwemi-5 (nokuba zigqibelele; ukunxiba kwangaphakathi akubonakali);Ukurhoxa amatyathanga emva kweminyaka emi-5-7 yokusetyenziswa kakhulu (ukuhlolwa kwamaxwebhu).
C. Amaxwebhu
-Gcina iinkuni ezinemihla, igama lomhloli, iziphumo kunye namanyathelo athathiweyo.
- Landela imigangatho: ASME B30.9 (Slings), OSHA 1910.184, EN 12195-3
