Sling Angle Inobata Sei Kukwanisa KweFlat Sling?

Chikwata chekubira chiri kusimudza ndiro yesimbi yematani matatu vachishandisa makumbo maviri chipfuramabwe chakafuratira . Gumbo rimwe nerimwe rechipfuramabwe rakatemerwa matani maviri. Mutoro unoratidzika kunge uri mukati mesimba-4 matani akazara, handiti? Asi makumbo echipfuramabwe akatambanudzwa pakona ye45°. Mutariri wekubira anoziva chokwadi: gumbo rega rega rave kutakura matani 2.1-kupfuura kugona kwaro kwakayerwa.

 

Mamiriro ezvinhu aya anoitika kazhinji kupfuura kubvuma kwevazhinji nyanzvi dzekubiridzira. Iyo kona yechipfuramabwe ndechimwe chezvakanyanya kukosha - uye kazhinji zvisinganzwisisike - zvinhu mumabasa ekusimudza akachengeteka.

 

Lishenflex  yanga ichigadzira machira akafuratira kweanopfuura makumi maviri emakore, uye ruzivo rwemumunda rwedu runoratidza kuti angle miscalculation ndiyo inotungamira chikonzero chekuremedza uye kutadza. Kunzwisisa hukama pakati pekona yekupfura uye kugona kwakakosha kune yega yega rigger, maneja, uye nyanzvi yekuchengetedza.

 

 

Sei Chipfuramabwe Chine Basa

Kana chipfuramabwe chakafuratirwa  chinoshandiswa mune yakatwasuka, yakatwasuka kusimudza, iyo yakazara yakayerwa kugona inowanikwa. Zvisinei, sezvo makumbo echipfuramabwe anoparadzirwa akaparadzana—kungava mubhasikiti kana kuti kusimudza makumbo akawanda—kumanikidzika kwegumbo rimwe nerimwe kunowedzera. Iyo idiki kona iri pakati pegumbo rechipfuramabwe uye rakachinjika (kana yakakura kona iri pakati pemakumbo), inokwirisa tension.

 

Kupinda kweWikipedia pazvipfuramabwe  kunotsanangura kuti Working Load Limit (WLL) yechipfuramabwe inomakwa pachipfuramabwe uye inosimudza yakatwasuka. Kana chipfuramabwe chikashandiswa pakona, WLL inofanira kuderedzwa, uye chiyero chakayerwa chinodzikira sezvo kona iri pakati pemakumbo echipfuramabwe inowedzera.

 

Iyo EN 1492-1  yakajairwa inotsanangura kudzikisa huwandu hwezvinhu zveflat slings dzinoshandiswa mune dzakasiyana hitch masisitimu:

 

Kunobva: EN 1492-1 flat webbing sling kugona zvinhu

 

ASME B30.9  inopa hutungamiri hwakafanana, hunoda kuti zviyero zvakatemerwa zvideredzwe kana zvipfuramabwe zvichishandiswa pamakona kana mumagadzirirwo emakumbo akawanda. Zvinoenderana neWikipedia's 'Ultraviolet' yekupinda, mafiber ekugadzira akaita sepolyester zvakare anotapukirwa nekushatiswa kweUV nekufamba kwenguva, izvo zvinogona kuwedzera kudzikisa kugona-kuita maengle maverengero akanyanya kukosha kune zvipfuramabwe zvinoshandiswa kunze.

 

Iyo Fizikisi yeSling angle

Hukama huripo pakati pemakona echipfuramabwe nekunetsana hunodzorwa neformula iri nyore:

 

Tension pagumbo = (Mutoro Weight ÷ Nhamba Yemakumbo) × Angle Factor

 

Chimiro chekona chinoverengerwa se: 1 ÷ sin(θ) -apo θ ndiyo kona iri pakati pegumbo rechipfuramabwe nendege yakachinjika.

 

Kwakabva: ASME B30.9 angle factor kuverenga

 

Sezvinoratidzwa netafura, sezvo kona inoderera, kushushikana kwegumbo rimwe nerimwe kunowedzera zvakanyanya. Pa 30 °, tension inopetwa kaviri vertical load pagumbo. Pa10 °, inoda kupeta katanhatu kuremerwa kwakatwasuka. Izvi zvinoreva kuti 2-ton flat sling pa30 ° inogona kutakura zvakachengeteka tani 1-hafu yehuwandu hwayo yakayerwa.

 

Lishenflex's lab yekuongorora inosimbisa kuti zvidhori zvinoshandiswa pamakona asina kudzika zvinonzwa zvakanyanya kushushikana pane iyo yakachinga nzvimbo uye maziso zvakabatanidzwa, kukurumidza kupfeka uye kuwedzera njodzi yekutadza.

 

Multi-Leg Slings uye Angle Factors

Paunenge uchishandisa ma-multi-leg slings (2-gumbo, 3-gumbo, kana 4-gumbo), iyo angle factor inofanirwa kuiswa kune rimwe nerimwe gumbo. Maererano neEncyclopedia Britannica's kupinda pamichina yakapfava , iyo mechanical advantage yesling inobatwa ne geometry yekusimudza-makona akafara anoderedza kukwanisa kusimudza kunobudirira.

 

Nzira inokurudzirwa yekusimudza makumbo akawanda:

 

1. Pima kona  pakati pegumbo rechipfuramabwe nerakatwasuka.

 

2. Sarudza kona yekona  kubva patafura (1/chivi θ).

 

3. Verenga tension pagumbo = (Mutoro ÷ Nhamba yemakumbo) × Angle factor.

 

4. Wona kuti tension yegumbo  rega rega haipfuure chipfuramabwe chakayerwa WLL.

 

Common Angle Mistakes

Iwo matatu anonyanya kuenderana zvikanganiso zvine chekuita nemakona mune flat sling rigging ndeaya:

 

1. Kutarisisa Angle Pakuverengera Total Capacity

 

Chikanganiso chakajairika kuwedzera maWLL egumbo rega rega rekupfura pasina kushandisa angle factor. Semuenzaniso, maviri 2-ton slings haapi matani mana ekukwanisa pa45 ° - anopa 2.8 matani chete (2 × 2t × 0.7 angle factor).

 

2. Kushandisa Wrong Reference Engle

 

Mamwe mareji anoyera kona iri pakati pemakumbo echipfuramabwe pane kuyera kona iri pakati pechipfuramabwe nechakatwasuka. The angle factor table inobva pakona kuenda kuhorizontal. Kona inosanganisirwa pakati pemakumbo inopeta kaviri kona kusvika kuhorizontal.

 

Quick reference:

 

90 ° yaisanganisira kona = 45 ° kune yakachinjika

 

120 ° yaisanganisira kona = 60 ° kusvika kune yakachinjika

 

30 ° yaisanganisira kona = 15 ° kusvika kune yakachinjika

 

3. Kuregeredza Kuderedzwa Kwesimba muBasket Hitches

 

Mubasket hitches, makumbo maviri anogovera mutoro, asi kona ichiri kushanda. Chimiro chekugona kwebhasikiti kurova ne 45 ° gumbo angle ndeye 1.4-kwete 2.0. Tafura mu EN 1492-1 inopa zvinhu chaizvo.

 

Inspection uye Verification

Iyo OSHA Nhungamiro paKuchengetedza Sling Kushandisa  inoda kuti kona yekukachidzwa uye kona yemakumbo ekutsvedza zvitariswe kana uchinge watemerwa huwandu. Kunyanya, iyo yakatemerwa mutoro wechipfuramabwe mune yakachinga hitch inoshanda chero iyo kona yekudzipwa i120 madhigirii kana kupfuura. Kune makona ekudzipwa asingasviki 120 madhigirii, iyo yakatarwa mutoro unofanirwa kuderedzwa.

 

Per ASME B30.9 , kuverenga kwehuwandu kunofanirwa kusimbiswa nemunhu ane hunyanzvi pamberi pekusimudza kwega kwega. Kugara uchiongorora kunofanirwa kuona kuti ma tag ekupfura anobatika, sezvo WLL ichidikanwa kuverenga mitoro yakachengeteka pamakona.

 

Kiyi yekubvisa maitiro pasi peASME B30.9 iyo inogona kukanganisa angle kugona:

 

Chisipo kana chisingaverengeki chiziviso tag-pasina WLL, kuverenga kwemakona hakugone kuitwa

 

Humbowo hwekukuvadzwa kweUV (kupera, kuomarara) - kunoderedza kugona kupfuura angle zvinhu

 

Kukuvadza kunoonekwa kunoderedza hupamhi hunobudirira-kukanganisa yakasara simba

 

Pfupiso uye Mazano Anoshanda

Iyo sling angle ndeimwe yezvinhu zvakanyanya kukosha zvinokanganisa flat sling kugona. Chipfuramabwe chakayerwa WLL chakavakirwa pakusimudzwa kwakamira, uye huwandu hunofanirwa kudzikiswa kana huchishandiswa pamakona.

 

Zvokudya zvakakosha:

 

1. Usambofa washandisa huwandu hweWLL usina kushandisa makona zvinhu - tension inowedzera sezvo kona inodzikira

 

2. Yera kona kune yakachinjika, kwete kona iri pakati pemakumbo

 

3. Tarisa kune matafura ekugona kwebhasiketi, kukachidzwa, uye akawanda-makumbo magadzirirwo

 

4. Ongorora ma tag ekupfura  kuti uone kuti WLL inonyoreka-isina iyo, kuverenga kwemakona hakugone kusimbiswa.

 

5. Funga nezvezvakatipoteredza zvinhu - UV uye kupisa zvinogona kuderedza huwandu kupfuura angle zvinhu

 

Lishenflex  inogadzira polyester flat slings ane mavara akajeka-coded capacity markings, inoenderana EN 1492-1 uye ASME B30.9 zviyero. Isu tinopa angle factor reference zvinhu uye pane-saiti kudzidziswa kuve nechokwadi chekuti timu yako inogona kuverenga mitoro yakachengeteka nemazvo.

 

Kana iwe uchida rubatsiro kuverenga yakachengeteka mitoro yekushanda kune yako chaiyo yekusimudza geometry-kana uchida rubatsiro kuona kana slings ako aripo akakodzera kukwirisa angled- ndokumbira utumire email kune sales@lishenflex.com , uye timu yedu yehunyanzvi ichapa rutsigiro rwemunhu-pamwe.
