Kodi Ndingagwiritse Ntchito Flat Sling mu Choke Hitch Configuration?

Anthu ogwira ntchito yoboola zingwe amafunika kukweza cylindrical katundu - chitoliro chachitsulo, mzati wa konkire, kapena mtolo wazitsulo. The lathyathyathya gulaye  iwo akathyole pa choyikapo ndi utali woyenera ndi mphamvu. Koma katunduyo alibe mfundo zolumikizira. Chombocho chimakulunga gulaye mozungulira katunduyo, chimadutsa diso limodzi kupyola linzake, n’kumachikoka mwamphamvu. Ichi ndi chokokera-ndipo chikhoza kukhala njira yothetsera vutoli, koma pokhapokha atachita bwino.

 

Lishenflex  yakhala ikupanga ma slings opangidwa ndi lathyathyathya kwazaka zopitilira makumi awiri, ndipo zomwe takumana nazo m'munda zikuwonetsa kuti kugunda kwapang'onopang'ono ndi ena mwa masinthidwe omwe amagwiritsidwa ntchito molakwika. Kugunda kwapang'onopang'ono kumawoneka kosavuta, koma kugwiritsa ntchito kwake kotetezeka kumadalira kumvetsetsa kuchepetsa mphamvu, kutsamwitsidwa koyenera, ndi momwe gulayesi imakhalira. Malinga ndi zomwe  makampani opanga sling EN 1492-1 amagwirizana nazo, choke hitch capacity factor ndi 0.8 - kutanthauza kuti gulaye yomwe idavotera tani imodzi pakukweza koyima imatha kunyamula ma kilogalamu 800 motetezeka.

 

Kodi Choke Hitch N'chiyani?

Kugunda kwachitsulo ndi njira yopangira gulaye pomwe gulaye imakulungidwa mozungulira katunduyo, ndipo mbali imodzi ya gulaye imadutsa diso lina kapena koyenera. Kenako katunduyo amakwezedwa, zomwe zimapangitsa kuti gulaye ikhwime mozungulira katunduyo. Izi zimapanga cinching zotsatira  zomwe zimatchinjiriza katunduyo ndikuletsa kutsetsereka.

 

Monga tafotokozera mu OSHA's Guide on Safe Sling Use , chokokera chokokera ndi choyenera kwa katundu wovuta kulinganiza kapena kutetezedwa ndi kukweza kowongoka kowongoka. Chokokeracho chimagwira katunduyo motetezeka pomangirira mozungulira. Komabe, OSHA imachenjeza mosapita m'mbali kuti pakugwedezeka, chokocho chiyenera kukhala pa thupi loponyedwa, osati pa splice kapena yoyenera.

 

Bungwe  la Rigging Institute  likunena kuti kugunda kwachitsulo ndi chimodzi mwazinthu zitatu zazikuluzikulu zoponyera, pambali zowongoka zoyima ndi madengu, ndipo zimagwiritsidwa ntchito nthawi zambiri ngati katundu alibe malo oyenera omata.

 

Kuchepetsa Mphamvu mu Choke Hitch

Chofunikira kwambiri pakugwiritsa ntchito kugunda kwamphamvu ndikuchepetsa mphamvu. Malire olemedwa ndi gulaye ndiokwera kwambiri pokoka mowongoka. Mukagwiritsidwa ntchito mu choke hitch, mphamvu imachepetsedwa kwambiri.

 

Malingana ndi OSHA Guide on Safe Sling Use , katundu wovomerezeka wa gulaye mu hitch choke amatsimikiziridwa ndi wopanga gulaye ndipo amachokera pa ngodya ya choke. OSHA imanena kuti kugunda kwamphamvu kumagwira ntchito ngati mbali ya choko ndi madigiri 120 kapena kuposa. Pa ngodya zotsamwitsa zosakwana madigiri 120, katundu woyengedwa uyenera kuchepetsedwa motsatira malingaliro a wopanga gulaye.

 

Tchati choyerekeza mphamvu (zotengera EN 1492-1 sling polyester flat sling):

 

Gwero: EN 1492-1 kuchuluka kwa data kuchokera ku CEREX ndi Mennens

 

Monga momwe tebulo likusonyezera, choke hitch factor (KL) ndi 0,8 pansi pa EN 1492-1, kuyimira kuchepetsa mphamvu 20% poyerekeza ndi kugunda kowongoka.

 

Kodi Choke Hitch Ndi Yoyenera Liti?

Kuthamanga kwa choke ndikoyenera muzochitika zina:

 

1. Katundu wopanda malo omangika ofotokozedwa - katundu wa cylindrical, mapaipi, mitolo ya rebar, ndi mizati ya konkriti

 

2. Katundu wofunika kugwidwa motetezedwa - kupewa kutsetsereka pokweza kapena kuzungulira

 

3.Kukweza mwendo umodzi -pamene kugunda kwa dengu sikutheka

 

Monga taonera ndi Medeer Lifting , kugunda kwa choke kumakhala kothandiza kunyamula katundu motetezeka koma sikukhazikika kuposa kugunda kolunjika ndipo kumatha kuwononga gulaye ngati ikugwiritsidwa ntchito molakwika. Ma gulaye okhawo omwe amapangidwa kuti azitsamwitsa ayenera kugwiritsidwa ntchito pokonza izi, ndipo gulaye iyenera kuyang'aniridwa kuti iwonongeke isanayambe kapena ikatha.

 

Kuchita bwino kwambiri:  Pakutsamwitsa, nsonga yotsamwitsa iyenera kuikidwa pa gulaye, osati pa diso, pa phazi, kapena pa nsonga . Ngodya ya choko iyenera kukhala 120 ° kapena kupitilira apo kuti musunge mphamvu zonse za 0.8.

 

Mfundo Zazikulu Zachitetezo

Osagwiritsa ntchito chokokera ngati:

 

● Cholowacho chimakhala ndi mabala, mikwingwirima, kapena kusokera pamalo amene angatsamwidwe

 

● Ngodya yotsamwitsa ndi yochepera 120 ° popanda kuchepetsa mphamvu

 

● Katunduyo ali ndi m'mbali zakuthwa zomwe zimatha kudula ulusi wa gulaye (gwiritsani ntchito zoteteza kumakona)

 

● gulaye ndi wopindika kapena wopindika—zimenezi zimachititsa kuti munthu asavutike

 

● Chizindikiritso cha gulayo palibe kapena ndi chosawerengeka—simungathe kutsimikizira kuchuluka kwake.

 

OSHA imaletsa mwatsatanetsatane:

 

● Silingi zokhala ndi mfundo (kufupikitsa kapena kutalikitsa mwa kupota kapena kupindika sikuloledwa)

 

● Kugwiritsa ntchito gulaye pogundana ndi nsonga yotsamwitsa pa nsonga kapena cholumikizira

 

● Kuika katundu pa legeni

 

● Kukoka gulaye pansi pa katundu pamene katunduyo ali pa gulaye

 

Kuyesa kwa labu la Lishenflex kumatsimikizira kuti ma slings omwe ali ndi kuwonongeka pang'ono-monga kukwapula komweko kapena kudulidwa kwa m'mphepete-zidziwitso zimafulumira kuvala pamasinthidwe a hitch chifukwa cha mphamvu yokhazikika pamtunda. Ichi ndichifukwa chake kugwiritsa ntchito zisanachitike komanso kuyendera pafupipafupi pa ASME B30.9 ndikofunikira kwambiri pama gulayeti omwe amagwiritsidwa ntchito poletsa kumenya.

 

Zofunikira pakuwunika pakugwiritsa ntchito Choke Hitch

Siling'ono zomwe zimagwiritsidwa ntchito pazitsulo zotsamwitsa ziyenera kuyang'aniridwa mobwerezabwereza kusiyana ndi zomwe zimagwiritsidwa ntchito pokweza molunjika. ASME B30.9  imafuna magawo atatu owunika:

 

Njira zazikulu zochotsera pansi pa ASME B30.9  pazitsulo zathyathyathya zomwe zimagwiritsidwa ntchito muzitsulo zotsamwa:

 

● Zolumikizira zothyoka kapena zotha kunyamula katundu

 

● Kupsa kwa asidi kapena caustic

 

● Umboni wa kuwonongeka kwa kutentha

 

● Mabowo kapena misozi imene imatulutsa ulusi pakatikati, makamaka pamene yatsamwitsidwa

 

● Kuvala zonyansa kwambiri

 

● Makondo mu thupi la gulaye—kulumikiza ndi koletsedwa pansi pa OSHA

 

● Maonekedwe amtundu kapena malo ophwanyika kusonyeza kuwonongeka kwa mankhwala kapena UV

 

Mwachidule ndi Malangizo Othandiza

Khola lathyathyathya  litha kugwiritsidwa ntchito pakusintha kwa choke hitch, koma kugwiritsa ntchito kuyenera kuyandikira mosamala komanso mwaluso.

 

Zofunikira zazikulu:

 

1. Kuchepetsa mphamvu sikungakambirane - kugunda kwamphamvu kumachepetsa WLL mpaka 80% ya mphamvu yoyimirira pansi pa EN 1492-1

 

2.Choke angle matters —sungani 120 ° kapena kupitilira apo kuti mukwaniritse 0.8 factor; kuchepetsa mphamvu ya ngodya zing'onozing'ono pa chitsogozo cha opanga

 

3. Osatsamwitsidwa pa nsonga kapena cholumikizira - nsonga yotsamwitsa iyenera kukhala pa thupi la gulaye.

 

4.Yang'anani musanagwiritse ntchito komanso mukamaliza - kutsamwitsa kumalimbikitsa kupsinjika; yang'anani kuwonongeka komweko

 

5.Gwiritsirani ntchito zotetezera kumakona —zonyamula zokhala ndi m’mbali zakuthwa

 

Lishenflex  imapanga masing'ilo a poliyesitala okhala ndi maso olimbikitsidwa komanso zolembera zowoneka bwino zamitundu, zogwirizana ndi EN 1492-1 ndi ASME B30.9 miyezo. Zogulitsa zathu zimayesedwa pamasinthidwe onse a hitch, kuphatikiza kugunda kwapang'onopang'ono, ndipo timapereka maphunziro owunikira kuti tithandizire machitidwe otetezeka.

 

Ngati mukufuna thandizo kuti muwone ngati ma slings anu aposachedwa ndi oyenera kutsamwitsidwa - kapena mukufuna chitsogozo pakuwerengera kuchuluka kwa geometry yanu yonyamula - chonde tumizani imelo kwa sales@lishenflex.com , ndipo gulu lathu laukadaulo lidzapereka chithandizo chamunthu payekha.
