Hi Yihi Mhaka Ya Vuhlayiseki 7:1 Naswona Ha Yini Swi Ri Swa Nkoka?

Mulanguteri wa rigging u hlawula a lifting sling  leyi ringanyetiweke eka 2 wa tithani. Ndzhwalo lowu wu tika tithani ta 1,5—eka mpimo lowu vekiweke swinene. Kambe ku humelela yini loko xibalesa xi tele hi switshuketa? Ku vuriwa yini loko ndzhwalo wu nga avanyisiwi hi ndlela leyi hoxeke? Ku vuriwa yini loko ku onhiwa ka mbango ku tsanise tifibre? Sling leyingana 7:1 safety factor yinyika buffer ya nkoka eka swiyimo leswi swinga languteriwangiki.

 

Lishenflex  yi endle swirhendzevutani swo tlakusa swilo leswi endliweke ku tlula makume mambirhi ya malembe, naswona xivutiso xin’we lexi hi xi twaka ngopfu eka vatirhisi va makumu hi lexi: Xana nomboro yoleyo ya 7:1 eka thegi yi vula yini hakunene? Nhlamulo i ya nkoka eka rigging leyi hlayisekeke—naswona hakanyingi a yi twisiseki.

 

Nchumu wa Vuhlayiseki vs. Mpimo wa Ndzhwalo wo Tirha: Ku twisisa ku hambana

Ku twisisa mhaka ya vuhlayiseki ya 7:1, u fanele ku rhanga u hambanisa exikarhi ka marito mambirhi ya nkoka: Working Load Limit (WLL) na Breaking Strength  (leswi tlhelaka swi vuriwa Minimum Breaking Load kumbe MBL) .

 

Hi ku ya hi Hercules Lifting guide , vuxaka exikarhi ka mimpimo leyi yimbirhi byi kumiwa hi xivangelo xa dizayini: WLL = Breaking Strength ÷ Design Factor .

 

bya 7:1 Vuhlayiseki  swivula leswaku matimba yo tshoveka ya sling ya phindhiwe ka nkombo eka WLL ya yona. Eka 1-ton WLL sling, matimba yo tshoveka ya kwalomu ka 7 tons. Hilaha swi hlamuseriweke hakona eka swiyimo swa indasitiri ku katsa na EN 1492-1 na EN 1492-2 , mpimo lowu i xilaveko xa le hansi xa swirhendzevutana swo endliwa .

Ha yini ku ri 7:1 eka Swilo swo Tlakusa leswi Endliweke?

Tinxaka to hambana ta switirhisiwa ti tirhisa swilo swo hambana swa vuhlayiseki :

 

Swirhendzevutana swa fibre yo endliwa swi lava xisirhelelo xa le henhla ku tlula ntambhu ya waya kumbe nketani hikuva swi le khombyeni swinene eka swilo swa mbango leswi nga onhaka matimba handle ka xilemukiso lexi vonakaka .

 

Hi ku ya hi WorkSafe WA’s Mines Safety Bulletin No. 155 , swirhendzevutana swa xirhendzevutana leswi endliweke swi le khombyeni ro onhaka emirini, ku vonakala ka dyambu (ultraviolet), tikhemikhali ni ku hisa ngopfu ku tlula mixaka yin’wana ya switirhisiwa swo tlakusa . Mhaka ya 7:1 yi nyika xisirhelelo eka swiyimo leswi swa xiviri leswi nga languteriwangiki.

 

Hilaha Lifting Gear Direct  yi vulaka hakona eka nkongomiso wa vona wa swilo leswi endliweke, ku cinca ka sweswinyana ka tiindasitiri ku lave leswaku tinxaka to karhi ta swirhendzevutana swo tlakusa leswaku ti va ni xisirhelelo xa 7:1 ematshan’weni ya mpimo wa khale wa 5:1—leswi vulaka leswaku swirhendzevutana sweswi swi ni ndzhwalo lowutsongo wo tshoveka lowu phindhiweke ka nkombo wa WLL ya swona .

 

Nkoka Wa Xiviri Wa Mhaka Ya Vuhlayiseki Ya 7:1

Mhaka ya 7:1 a hi ya ku tihlawulela. Yi hlamusela : .

 

Shock loading —ku layicha ka xitshuketa kumbe ku humesiwa

 

Ku famba-famba loku cinca-cincaka —ku rhendzeleka kumbe ku cinca-cinca hi nkarhi wa ku tlakusa

 

Ku onhiwa ka mbango —Ku onhiwa ka UV, tikhemikhali kumbe ku hisa hi ku famba ka nkarhi

 

Ku onhaka ni ku handzuka —ku rhurhumela, ku tsemiwa ni ku onhaka ka makumu

 

Swilo swa angle —ku hunguteka ka vuswikoti eka ti choke kumbe ti basket hitches

 

Ku tiyisela ka vumaki —ku hambana ka swilo ni ku aka

 

Hi ku ya hi CERTEX Denmark , swirhendzevutana swa malapi lama endliweke swi le khombyeni ngopfu-ngopfu eka matlhelo lama karihaka, ku onhaka ni ku hlangana, ku tsemiwa ni ku handzuka, ku hisa loku tlulaka mpimo lowu pfumeleriweke wa mahiselo, tikhemikhali leti nga fambisaniki ni ku hlangana ni UV hi ku famba ka nkarhi . Nchumu wa vuhlayiseki wa 7:1 wu nyika margin eka vuhlayiseki lebyi, ku tiyisisa leswaku sling leyi onhiweke hi ku onhaka lokuntsongo ka mbango yi nga ha va ya ha ri na matimba lama saleke lama eneleke ku khoma ndzhwalo wa yona lowu ringanyetiweke hi ku hlayiseka.

 

Lishenflex ’s lab testing yi tiyisisa leswaku hambi kuri ku tsemiwa ka 10% edge—leswi swinga hundza eka ku hatlisa ka pre-use check—swinga hunguta vuswikoti bya sling hi 35%. Nchumu wa 7:1 wu tiyisisa leswaku xirhendzevutani lexi onhakeke kutsongo xi nga ha hlayisa matimba lama eneleke ku tlakusa ndzhwalo wa xona lowu ringanyetiweke. Leswi hi swona swi endlaka leswaku mhaka ya vuhlayiseki leyi tlakukeke yi nga ri xilaveko xa ku landzelela ntsena—i xilaveko lexi tirhaka.

 

Ndlela Leyi Mhaka Ya Vuhlayiseki 7:1 Yi Vonakaka Ha Yona Hi Ku Tirhisa

Ehansi ka EN 1492-1 na EN 1492-2, xivangelo xa vuhlayiseki xa 7:1 xi hlanganisiwile na swikoweto swa vuswikoti leswi khodiweke hi mihlovo :

 

Xihlovo: EN 1492-1/2 swipimelo swa khodi ya mihlovo

 

DIN EN 1492-2  yivula leswaku swirhendzevutani swifanele kuva na vuhlayiseki byale henhla bya 7:1, leswivulaka leswaku WLL ya 1000 kg yi fambelana na ndzhwalo wo tshoveka wa 7000 kg . Nhlamuselo ya xiendliwa xa SpanSet yi tiyisisa leswaku swirhendzevutani swa vona swa webbing ya xiphepherhele swi endliwe hi xivangelo xa vuhlayiseki xa 7:1, laha xiendliwa xin’wana na xin’wana xi nyikiwaka xitifikheti xa ku fambisana na nomboro yo hlawuleka ya xirhendzevutani ku landzelerisa .

 

Mimpimanyeto Leyi Lerisaka 7:1

Nchumu wa vuhlayiseki wa 7:1 wu lerisiwe hi swipimelo swo tala swa matiko ya misava swa swirhendzevutana swo endliwa:

 

WorkSafe WA  yi tiyisisa leswaku eka swirhendzevutani swa polyester leswi landzelaka AS 4497:2018, ndzhwalo wa le hansi wo tshoveka wu phindhiwe ka nkombo wa WLL ya vona , naswona hi voxe va proof-loaded ku ya eka WLL ya vona leyi phindhiweke kambirhi .

 

Nkatsakanyo na Switsundzuxo leswi Tirhaka

Nchumu wa vuhlayiseki wa 7:1  i parameter ya nkoka ya dizayini leyi nyikaka margin ya vuhlayiseki exikarhi ka matimba yo tshoveka ya sling yo tlakusa na mpimo wa ndzhwalo wa yona wo tirha. Mhaka leyi yi hlamusela swiyimo swa xiviri—ku layicha hi ku chava, ku onhiwa ka mbango, ku onhaka ni swilo swa angle—leswi nga kavanyetaka matimba ya xirhendzevutani.

 

Swilo swa nkoka leswi tekiwaka:

 

1.7:1 yi lerisiwe hi EN 1492-1/2 na AS 4497:2018  eka swirhendzevutani swo endliwa

 

2.WLL a hi matimba yo tshoveka —u nga tshuki u tirhisa matimba yo tshoveka tanihi mpimo wo tirha

 

3.The higher safety factor for synthetics yi vangiwa hi ku va ekhombyeni ra tona  eka UV, ku hisa, tikhemikhali, na ku onhaka ka miri

 

4.Minkarhi hinkwayo kambela sling tag —yi kombisa WLL na safety factor

 

5.Kambela nkarhi na nkarhi —xiyenge xa ​​7:1 i xisirhelelo, ku nga ri xisirhelelo xa ku hlayisiwa loku faneleke

 

Lishenflex  yi endla swirhendzevutani swo tlakusa swa synthetic leswingana 7:1 safety factor, leswi fambisanaka na EN 1492-1 na EN 1492-2 standards. Switirhisiwa swa hina swi na swikoweto swa vuswikoti leswi nga erivaleni leswi nga na khodi ya mihlovo, tinomboro to hlawuleka ta xirhendzevutani ku landzelerisa, naswona swi layichiwile hi vumbhoni ku tiyisisa ku tshembheka.

 

Loko u lava mpfuneto wo twisisa swilaveko swa xivangelo xa vuhlayiseki eka matirhelo ya wena yo karhi yo tlakusa—kumbe u lava mpfuneto wo tiyisisa leswaku swirhendzevutani swa wena swi fikelela swipimelo leswi lavekaka—hi kombela u rhumela imeyili eka sales@lishenflex.com , naswona ntlawa wa hina wa xithekiniki wu ta nyika nseketelo wa munhu hi xiyexe.
