'Nthano Yotsika mtengo': Chifukwa Chake Kukweza Slings Ndi Njira Yotetezeka Kuchokera ku Wire Rope

Ogwira ntchito zamagalimoto akukonzekera kukweza chitsulo chosapanga dzimbiri chopukutidwa. Katunduyo ndi wamtengo wapatali madola masauzande ambiri ndipo ali ndi malo omalizidwa omwe sangathe kukanda kapena kuipitsidwa. Woyang'anira amafika ku a kunyamula gulaye —osati chifukwa chakuti n’chotchipa, koma chifukwa chakuti n’chotetezeka ku katundu.

Komabe nthano yosalekeza idakalipo: kuti gulaye zopangira ndi 'njira yotsika mtengo' yopangira chingwe. Monga momwe bungwe la Occupational Safety and Health Administration (OSHA) limanenera, masing'i opangira amapezeka muzinthu zosiyanasiyana ndi zomangamanga, chilichonse chimapereka maubwino ake kutengera momwe amagwiritsira ntchito. Kulowa kwa Wikipedia pa chingwe chawaya kumafotokoza kuti chingwe chawaya chimapangidwa ndi zingwe zingapo zachitsulo zopindidwa kukhala helix, pomwe masing'ono opangidwa amapangidwa kuchokera ku ulusi wokhazikika kwambiri monga poliyesitala, nayiloni, kapena polypropylene.

Lishenflex yakhala ikupanga zonyamula zonyamula zopangira kwazaka zopitilira makumi awiri, ndipo zomwe takumana nazo zikuwonetsa kuti 'chizindikiro chotsika mtengo' sichimangolakwika - ndichowopsa. Mainjiniya ndi akatswiri ogula zinthu akamawona ma slings opangira ngati zinthu zamtundu wachiwiri, amatha kunyalanyaza zabwino zomwe amapereka.

Ubwino Wachitetezo 1: Kuteteza Katundu

Ubwino wofunikira kwambiri wa zonyamula zopangira zonyamula pamwamba pa zingwe za waya ndikuteteza katundu.

Kupewa Zowonongeka Pamwamba

Chingwe chawaya, chokhala ndi zingwe zake zachitsulo, chimatha kukanda, kusokonekera, kapena kuwononga malo osalimba. Malinga ndi Wikipedia yolowera pa chingwe chawaya , chingwe chawaya chimapangidwa ndi zingwe zingapo zachitsulo zomwe zimatha kuluma pamalo ovutikira. Zovala zopangira, mosiyana, zimapangidwa kuchokera ku ulusi wofewa, wosasunthika womwe umagwirizana ndi katundu.

CERTEX Denmark imatsimikizira kuti zitsulo zopangidwa ndi nsalu zopangira nsalu ndizomwe mungasankhe pazinthu zomwe zimafuna chitetezo cha pamwamba, chifukwa sizidzawononga pamwamba pa katunduyo. Florida Lifting mofananamo imanena kuti zingwe za zingwe zimakhala zopweteka ndipo zimatha kuwononga malo onyamula katundu , pamene ma slings opangidwa amasinthasintha ndi mawonekedwe a katundu.

Kugawa kwa Pressure

Ma gulayeni opangidwa amagawa kulemera kwa katundu pamalo olumikizana ambiri kuposa chingwe cha waya, kuchepetsa kuthamanga kwa pamwamba ndikuchepetsa chiopsezo chophwanyidwa kapena kupunduka. Izi ndizofunikira kwambiri pa katundu wosalimba kapena womalizidwa - chingwe chopanda waya chimatha kupanga zolemetsa zomwe zimalowera mkati kapena kung'ambika, pomwe gulayeti yopangidwa imafalitsa mphamvuyo mofanana.

Ubwino Wachitetezo 2: Kuthamanga Kwambiri

Masing'ong'ong'onya onyamulira amayamwa bwino kwambiri kuposa chingwe cha waya.

Mphamvu mayamwidwe

Malingana ndi Liftex's web sling guide , gulayeni zopangira zimakhala ndi zinthu zabwino kwambiri zoyamwitsa . Amatha kuyamwa katundu wodzidzimutsa popanda kusinthika kosatha, kuchepetsa mphamvu zomwe zimaperekedwa ku katundu pazochitika zonyamula katundu. Chingwe chawaya, mosiyana, chimakhala ndi mphamvu zochepa zamayamwidwe ndipo zimatha kuonongeka ndi katundu wodabwitsa.

Zokolola ndi Kuchira

Chingwe cha mawaya, chikachulukidwa, chimatha kubereka mpaka kalekale ndipo sichingalephereke nthawi yomweyo, zomwe zimapangitsa kuti pakhale ngozi yogwiritsa ntchito gulaye yomwe yawonongeka kale. Zovala zopangira, ngakhale zitatambasula, zimatha kubwerera kutalika kwake ngati katunduyo atachotsedwa mkati mwa malire awo otanuka.

Ubwino Wachitetezo 3: Chizindikiro Chowonongeka

Ubwino umodzi wofunikira kwambiri wachitetezo cha ma silings onyamula opangira ndi kuthekera kwawo kupereka zizindikiro zowonekera zisanachitike.

Zizindikiro Zowonongeka Zowoneka

Ma slings opangidwa amawonetsa zizindikiro zoonekeratu za kuwonongeka ndi kuwonongeka asanalephereke. Malinga ndi mawu a Wikipedia a 'Sling (rigging)' , ma gulayeni opangidwa amawonetsa zizindikiro zowonekera bwino monga , , kuuma kwamphamvu ndi kuvala pamwamba kusanawonongeke koopsa. Chingwe cha waya, mosiyana, chikhoza kulephera mwadzidzidzi komanso popanda chenjezo looneka.

Pa ASME B30.9 , zoponyera zopangira zowonongeka zowonongeka-kudula, kuphulika, kutentha kwa mankhwala, kuwonongeka kwa kutentha-kuyenera kuchotsedwa kuntchito, kupatsa ogwira ntchito nthawi kuti azindikire ndikusintha ma slings owonongeka.

Kuyendera Kwambiri

Kuwonongeka kwamkati kwa waya kumakhala kovuta kuzindikira popanda zida zapadera. Komabe, ma gulayeni opangidwa amatha kupindika ndi kupanikizidwa kuti awonetse kuwonongeka kwa ulusi wamkati, njira yowunika yomwe imachenjeza msanga za kuwonongeka.

Ubwino wa Chitetezo 4: Kusinthasintha ndi Kusinthasintha

zonyamula Zopangira zonyamula zimapereka kusinthasintha komanso kusinthasintha kuposa chingwe cha waya.

Ma Hitch Configurations

Malinga ndi CERTEX Denmark , zoponyera zopangira zimatha kusinthidwa kuti zikhale pafupifupi ntchito iliyonse yokweza, yokhala ndi masinthidwe osiyanasiyana (diso & diso, zopanda malire, mwendo umodzi, miyendo yambiri). Zingwe zoponyera zingwe ndizochepa kusinthasintha kwake ndipo sizingagwirizane ndi mawonekedwe olemetsa osagwirizana bwino.

Katundu Conformity

Zovala zopangira zopangira zimagwirizana ndi mawonekedwe a katunduyo , zomwe zimapereka kulumikizana kwabwinoko ndikuchepetsa chiopsezo choterereka. Zingwe zoponyera zingwe ndizolimba ndipo sizingafanane ndi mawonekedwe osakhazikika, zomwe zimawonjezera chiopsezo chosuntha katundu.

Ubwino Wachitetezo 5: Kulemera ndi Kugwira

ndi Masing'ong'onya onyamula opepuka kwambiri kuposa mawaya omwe amatha kufananiza nawo.

Kuchepetsa Kuopsa kwa Musculoskeletal

Ma slings opepuka amachepetsa chiopsezo cha kuvulala kwa minofu ndi mafupa panthawi yogwira ndikuyika. Ogwira ntchito savutika kuti adzikakamize pokweza ndi kuika mawaya olemetsa. Malinga ndi Liftex , masing'i opangidwa ndi 30-70% opepuka kuposa ma slings a waya omwe amatha kufanana.

Kufananiza Chidule

Gwero: Zambiri zamakampani; CERTEX Denmark; Liftex; OSHA

Pamene Waya Chingwe Ndi Chosankha Chabwino

Ngakhale zabwino zopangira zonyamula zonyamula , chingwe chawaya chimakhala chisankho chabwinoko pazinthu zina:

• Kutentha kwambiri - pamwamba pa 90 ° C (194 ° F) popanga gulayeni

• Malo obisalamo —momwe mbali zakuthwa kapena zokhotakhota zimatha kudula ulusi wopangidwa

• Zonyamula zolemera kwambiri —kumene gulayeni zopangira sizipezeka mu mlingo wofunikira

Mwachidule ndi Malangizo Othandiza

'Nthano yotsika mtengo' ndi malingaliro olakwika owopsa. Masing'ong'ong'onyedwe onyamula siwongowononga ndalama - nthawi zambiri amakhala otetezeka, kusankha kothandiza kwambiri pamachitidwe amakono okweza.

Zofunikira zazikulu:

1. Ma gulayeti opangidwa amateteza katundu —malo ofewa amalepheretsa kukanda ndi mano

2. Zoponyera zopangira zimakoka kugwedezeka —kuchepetsa mphamvu zazikulu pazochitika zamphamvu

3. Mapulani opangidwa amawonetsa zizindikiro zochenjeza - kuwonongeka kowoneka kumasonyeza pamene kupuma pakufunika

4. Zovala zomangira zimasinthasintha komanso zopepuka - zimagwirizana ndi katundu komanso kuchepetsa kuwopsa kwa kuwongolera

5. Chingwe chawaya chimagwiritsidwa ntchito mwapadera - kutentha kwambiri, malo owopsa, ndi katundu wambiri

Lishenflex imapanga zitsulo zonyamulira za polyester ku EN 1492-1 ndi ASME B30.9 miyezo, yopereka chitetezo chapamwamba cha katundu, mayamwidwe ogwedezeka, ndi zizindikiro zowonongeka. Zogulitsa zathu zimapezeka mumasinthidwe osiyanasiyana ndi mphamvu kuchokera pa 1 toni mpaka 10 toni.

Ngati mukufuna thandizo lofananiza gulaye ndi zingwe zamawaya pakugwiritsa ntchito kwanu - kapena ngati mukufuna thandizo posankha legeni yoyenera kuti mugwire ntchito - chonde tumizani imelo kwa sales@lishenflex.com , ndipo gulu lathu laukadaulo lidzapereka chithandizo chamunthu payekha.
