Chii chinonzi 7: 1 Chengetedzo Chinhu uye Nei Zvine Basa?

Mutariri wekucheka anosarudza a kusimudza chipfuramabwe  chakayerwa matani maviri. Mutoro unorema matani 1.5-zvakanaka mukati memuganhu. Asi chii chinoitika kana chipfuramabwe chikatyamadzwa? Zvakadini kana mutoro wacho ukasafungwa zvakanaka? Zvakadini kana kushatiswa kwemhoteredzo kwanetesa faibha? Chipfuramabwe chine 7: 1 kuchengetedza chinhu chinopa yakakosha buffer kune aya asingafungidzike mamiriro.

 

Lishenflex  yanga ichigadzira zvidhori zvekusimudza kweanopfuura makumi maviri emakore, uye mubvunzo mumwe watinonzwa kazhinji kubva kuvashandisi vekupedzisira ndewekuti: Ko iyo 7:1 nhamba patiki inorevei chaizvo? Mhinduro yakakosha pakubiridzira kwakachengeteka-uye kazhinji hainzwisiswe.

 

Safety Factor vs. Working Load Limit: Kunzwisisa Musiyano

Kuti unzwisise 7: 1 kuchengetedza chinhu, iwe unotanga kusiyanisa pakati pemashoko maviri anokosha: Working Load Limit (WLL) uye Breaking Strength  (inonziwo Minimum Breaking Load kana MBL) .

 

Maererano neHercules Lifting guide , hukama huri pakati pezvinhu zviviri izvi zvinogadziriswa nekugadzira chinhu: WLL = Kuputsa Simba ÷ Dhizaini Factor. .

 

A 7:1 chengetedzo  inoreva kuti simba rechipfuramabwe rinotyora kanomwe WLL yacho. Kune 1-ton WLL chipfuramabwe, simba rekupwanya rinokwana matani manomwe. Sezvinotsanangurwa mumaindasitiri zviyero zvinosanganisira EN 1492-1 uye EN 1492-2 , reshiyo iyi ndiyo diki inodiwa pazvipfuramabwe zvekugadzira.

Sei 7:1 yeSynthetic Lifting Slings?

Mhando dzakasiyana dzemidziyo dzinoshandisa dzakasiyana chengetedzo zvinhu:

 

Synthetic fiber slings inoda yakakwirira kuchengetedza chinhu kupfuura tambo yewaya kana cheni nekuti ivo vari panjodzi yezvakatipoteredza izvo zvinogona kuderedza simba pasina yambiro inooneka.

 

Maererano neWorkSafe WA's Mines Safety Bulletin No. 155 , zvipfuramabwe zvakatenderedzwa zvinonyanya kukuvadzwa nekukuvara kwemuviri, chiedza chezuva (ultraviolet), makemikari, uye kupisa kwakanyanya kudarika mamwe marudzi ekusimudza gear. Iyo 7: 1 chinhu chinopa buffer kupokana neaya asingafungidzike mamiriro epasirese.

 

Sezvo Lifting Gear Direct  zvinyorwa muhutungamiri hwavo hwechigadzirwa, shanduko dzemazuva ano dzemaindasitiri dzakada mamwe marudzi ekusimudza slings kuti ave ne7: 1 kuchengetedza chinhu pane chekare 5: 1 ratio-zvinoreva kuti slings iye zvino ane zvishoma kuputsa mutoro kanomwe WLL yavo.

 

Iko Kukosha Kwepasirese kwe7: 1 Chengetedzo Factor

Iyo 7: 1 factor haisi yekungoita. Inomiririra:

 

Shock loading - kamwe-kamwe kurodha kushandiswa kana kusunungurwa

 

Dynamic movement - kuzunguzika kana kushandura panguva yekusimudza

 

Kushatisa kwezvakatipoteredza - UV, makemikari, kana kupisa kukuvadza nekufamba kwenguva

 

Pfeka uye kubvaruka -kupwanya, kuchekwa, uye kukuvara kumucheto

 

Angle factor - kuderedza kugona mukukachidzwa kana bhasikiti

 

Kushivirira kwekugadzira -kusiyana kwezvinhu uye kuvaka

 

Sekureva kweCERTEX Denmark , machira ekugadzira machira ari panjodzi yekupinza mipendero, kupfeka uye kukweshana, kucheka nemisodzi, kupisa kuri pamusoro petembiricha inobvumidzwa, makemikari asingaenderane, uye kuratidzwa kweUV nekufamba kwenguva. Iyo 7: 1 kuchengetedza chinhu chinopa muganho wekusagadzikana uku, kuve nechokwadi chekuti chipfuramabwe chakasvibiswa nediki kukuvara kwezvakatipoteredza chinogona kunge chiine simba rakakwana rekubata mutoro wayo wakayerwa zvakachengeteka.

 

Lishenflex 's lab yekuongorora inosimbisa kuti kunyangwe 10% kuchekwa-kunogona kupotsa nekukurumidza-pre-use cheki-kunogona kuderedza sling kugona ne35%. Iyo 7: 1 chinhu chinovimbisa kuti chipfuramabwe chine kukuvara kudiki chinogona kuramba chiine simba rakakwana kuti risimudze mutoro waro wakayerwa. Ichi ndicho chikonzero chepamusoro chekuchengetedza chisiri chinodikanwa chekuteedzera chete - chinhu chinodikanwa.

 

Iyo 7:1 Chengetedzo Factor Inoratidzika Mukuita

Pasi pe EN 1492-1 uye EN 1492-2, iyo 7: 1 kuchengetedza chinhu chinosanganiswa nemavara-coded kugona mamaki.

 

Kunobva: EN 1492-1/2 mavara-code zviyero

 

DIN EN 1492-2  inotaura kuti zvipfuramabwe zvakatenderedza zvinofanirwa kunge zvine kuchengetedzwa kwepamusoro kwe7: 1, zvichireva kuti WLL ye1000 kg inoenderana nekuremerwa kwe7000 kg. Mamiriro echigadzirwa cheSpanSet anosimbisa kuti slings yavo yakafuratira inogadzirwa ne7: 1 kuchengetedza chinhu, nechigadzirwa chega chega chinopihwa chitupa chekuenderana uye yakasarudzika serial nhamba yekuteedzera.

 

Mitemo Inorayira 7:1

Iyo 7: 1 yekuchengetedza chinhu inorairwa neakawanda epasi rose zviyero zvekugadzira zvipfuramabwe:

 

WorkSafe WA  inosimbisa kuti kune polyester round slings inoenderana neAS 4497: 2018, iyo shoma yekutyora mutoro inopetwa kanomwe WLL yavo , uye iwo ega ega anoremerwa kusvika kaviri WLL yavo.

 

Pfupiso uye Mazano Anoshanda

Iyo 7: 1 kuchengetedza chinhu  chakakosha dhizaini dhizaini inopa chengetedzo muganho pakati pekusimudza chipfuramabwe chekupwanya simba uye kushanda kwayo mutoro. Ichi chinhu chinokonzeresa mamiriro epasirese-kuremerwa kwekuvhundutsa, kukanganisa kwezvakatipoteredza, kupfeka, uye makona zvinhu-izvo zvinogona kukanganisa simba rekupfura.

 

Zvokudya zvakakosha:

 

1.7:1 inorairwa ne EN 1492-1/2 uye AS 4497:2018  yekugadzira zvipfuramabwe

 

2.WLL haisi kuputsa simba - usamboshandisa kuputsa simba semuganhu wekushanda

 

3. Iyo yepamusoro yekuchengetedza chinhu chekugadzira imhaka yekusagadzikana kwavo  kuUV, kupisa, makemikari, uye kukuvara kwemuviri.

 

4.Gara uchitarisa sling tag -inoratidza zvose WLL uye kuchengetedza chinhu

 

5.Ongorora nguva dzose —iyo 7:1 chinhu chivhariso, kwete chinotsiva kugadzirisa kwakakodzera

 

Lishenflex  inogadzira masingano ekusimudza ane 7: 1 kuchengetedza chinhu, inoenderana ne EN 1492-1 uye EN 1492-2 zviyero. Zvigadzirwa zvedu zvinoratidzira mavara akajeka-akadhindwa makiyi, akasarudzika manhamba ekuteedzera, uye ane humbowo-akatakura kuti ave nechokwadi chekuvimbika.
