Indlela yokubala Umthamo weNtsontelo yeNtsontelo yokuLinga

1. Intshayelelo: Amandla angabonakaliyo eZilingi zeeNtsontelo zocingo

Izilingi zentambo zocingo zizixhobo ezibalulekileyo kumashishini anzima afana nemisebenzi yaselwandle, imigodi, i-oyile negesi, ulwakhiwo, ukuvelisa, kunye nolungiselelo, njl.njl. Zibalulekile ekuphakamiseni nasekukhuseleni imithwalo emikhulu, zisebenza ngokuthembekileyo ngenxa yamandla azo, ukuqina, kunye nokuxhathisa ubushushu kunye nokukrazuka.

Nangona kunjalo, ukusetyenziswa ngokukhuselekileyo kufuna ulwazi lobuchwephesha lokuphakama kwamandla. Ukhuseleko alwazi nto; ukusilela kwesilingi kukhokelela kwiingozi ezinzulu zokhuseleko—ukuqhekeka kwezixhobo, ukuwisa imithwalo, ukwenzakala okumanyumnyezi, kwanokubulala. Esi sikhokelo sinika indlela yobuchwephesha yokulawula ezi zibalo, ukuqinisekisa ukuba imisebenzi yakho yokuphakamisa ihlangabezana neyona migangatho iphezulu yokhuseleko kwaye ithobela imimiselo evela kwimizimba efana ne-OSHA, ASME, kunye nemigangatho ye-EN.

2. Kutheni ukubalwa koMmandla wokuLinga okuchanekileyo kubalulekile?

Ukubalwa komthamo wesilingi okuchanekileyo kusisiseko kwimfezeko yokusebenza, okuchaphazela ngokuthe ngqo ukhuseleko, ukuthotyelwa kwemithetho, kunye nomgca ophantsi wakho. Ukwazi umthamo wokwenyani wesilingi kubalulekile ukunqanda ukugcwala kakhulu kunye nokuphepha iingozi, ukunciphisa umonakalo wesixhobo kunye nexesha lokunciphisa iindleko, kunye nokufezekisa ukunyuswa okugudileyo, okuqikelelweyo.

Ukugcwala kakhulu kuzuza imingcipheko yokusilela ngequbuliso, ukwenzakala, kunye nokufa. Ngaphandle kweendleko zomntu, ukusilela kukhokelela kwilahleko enkulu yemali. Ubalo lwamandla oluchanekileyo lukhuseleko lwakho oluphambili. Ukuthobela imigangatho yoshishino (OSHA, ASME, EN 13414-1) yinto esemthethweni nesesikweni, eqinisekisa ukhuseleko olungaguqukiyo. Ubalo olufanelekileyo kunye nokubambelela kwi-WLL kukwathintela ukunxitywa kwangaphambi kwexesha, ukolula ubomi besilingi kunye nokuphucula imbuyekezo yakho kutyalo-mali .

3. Ukuqonda i-Wire Rope Slings: Ukwakhiwa kunye noMahluko ongundoqo

Ukubamba okuqinileyo kwe intambo yocingo isilingi ulwakhiwo kunye neentlobo ezingundoqo zibalulekile ekumiseleni umthamo ochanekileyo kunye nokusetyenziswa okukhuselekileyo.

3.1. Ulwakhiwo (umzekelo, 6×19, 6×36, 7×19)

Ukwakhiwa kweentambo zocingo kumisela ukuguquguquka kwayo, ukomelela, kunye nokuchasana nokukrazula okanye ukudinwa.

3.2. Indima yeNqaku: I-Fiber Core vs. I-Independent Wire Rope Core

Undoqo uxhasa imicu kwaye ugcina ubume bentambo, obuchaphazela amandla, ukuqina, kunye nokuxhathisa kokusingqongileyo.

I-FC ibonelela ngokuguquguquka okukhulu kunye nokufunxa ukothuka, ilungele imithwalo elula kunye nokugoba rhoqo. Amandla angaphantsi kokuqina, athanda ukutyunyuzwa, kwaye akufanelekanga kubushushu obuphezulu (ngaphezu kwe-180℉/82℃).

I-IWRC inika amandla aphezulu, ukuqina, kunye nokuchasana okugqwesileyo ukutyumza kunye nobushushu obuphezulu. I-IWRC yongeza malunga ne-7.5% kumandla entambo engundoqo.

Ukhetho luxhomekeke kumthamo womthwalo, iimfuno zokuguquguquka, kunye neemeko zokusingqongileyo.

3.3. Ulungelelwaniso oluQhelekileyo lwe-Sling: Ngokuthe nkqo, iChoker, iBhaskithi, kunye neMiqalo yeMilenzi emininzi

Indlela isilingi esisetyenziswa ngayo iyawatshintsha amandla aso okuphakamisa.

• Ukuphakamisa ngokuthe nkqo: Ukutsalwa ngokuthe ngqo, kusetyenziswa i-WLL epheleleyo.
• I-Choker Hitch: I-Sling ijikeleze umthwalo, ukunciphisa umthamo nge-20-25% (i-angle ingaphantsi kwe-120 °). Indawo yokukhahlela kufuneka ibe kumzimba wesilingi.
• I-Basket Hitch: I-Sling idlula phantsi komthwalo, amehlo omabini adibanisa. Inokuba nomthamo ophindwe kabini ukuba imilenze ithe nkqo kwaye umlinganiselo we-D/d ulungile. Umthwalo kufuneka ulinganiswe.
• I-Multi-Leg Bridle Slings: Isetyenziselwa iindawo ezininzi zokunamathisela. Umthwalo usasazwa, kodwa i-angle yemilenze ibaluleke kakhulu; njengoko imilenze iyancipha, ukunyanzeliswa komlenze ngamnye kwanda kakhulu, ukunciphisa umthamo jikelele. Soloko usebenzisa eyona engile incinci ethe tye ekubaleni.

4. Imiba ephambili enefuthe kwisakhono sokuLinga ngeNtsontelo yeNtambo

Ngaphaya kweleyibhile, izinto ezininzi ezitshintsha ngamandla amandla okuphakamisa isilingi: Idayamitha yeNtsontelo, iEngile yokuLinga, uBumbeko lwesiLingi, iMathiriyeli yesiLingi kunye noKwakha, kunye neFactor yoKhuseleko.

4.1. MBL kunye neWLL

I-MBL ngawona mandla aphantsi okumelana nentambo yocingo entsha phambi kokuba yaphulwe, ebonelelwe ngumenzi. I-WLL ngowona mthwalo ukhuselekileyo. I-WLL ithathwe kwi-MBL ngokusebenzisa iFactor yoKhuseleko.

Ukuphakanyiswa ngokubanzi, umgangatho we-SF uqhelekile ngu-5: 1 kwimigangatho yase-US kunye ne-EN (i-WLL yi-20% ye-MBL). Ii-SF eziphezulu (umz., 10:1) ziyafuneka xa kunyuswa abasebenzi.

I-WLL= Into yoKhuseleko/MBL

4.2. Impembelelo ebalulekileyo ye-Sling angle

I-engile yesilingi ichaphazela kakhulu umthamo wokuphakamisa osebenzayo. Njengoko i-angle phakathi kwemilenze ye-sling kunye ne-horizontal iyancipha, ukuxinezeleka emlenzeni ngamnye kwanda kakhulu, ukunciphisa umthamo jikelele. I-engile ethe tyaba engama-30° iwenza abe sisiqingatha umthamo. 

Ukuba i-engile ilinganiswa ukusuka kwi-horizontal, i-Angle Factor sisono.

I-WLL ehlengahlengisiweyo =WLL (Nkqo)×Iengile Factor

Ii-engile ezithe tyaba ngaphantsi kwe-30° azikhuselekanga. Zombini imigangatho ye-US kunye ne-EN ibonelela ngezikhokelo zohlengahlengiso lwe-angle.

4.3. Idayamitha yeCurvature (D/d Ratio):

Umlinganiselo we-D/d uthelekisa ububanzi bento isilingi esijikela kuyo (D) nesangqa sentambo (d). Ukugoba intambo ngedayamitha encinci kakhulu kwandisa uxinzelelo kunye nokudinwa, kunciphisa kakhulu umthamo (umzekelo, i-D/d = 1:1 inokunciphisa amandla ngama-50%).

Ubuncinci obucetyiswayo bomlinganiselo weD/d: Ukwahlulwe ngoomatshini: 25:1; Isandla Sahlulwahlulwa: 15:1; Iinxalenye ezininzi ezilukiweyo: 25:1. Ngalo lonke ixesha sebenzisa iithimbles kumehlo esilingi kwaye ukhusele izilingi ngezinto ezithambisayo okanye uzithintele kwiikona ezibukhali.

4.4. Uhlobo lwesilingi kunye noKusebenza ngokuFanelekileyo

Umthamo ukwaphenjelelwa luhlobo lwayo (umzekelo, inxalenye enye, ibraided, grommet) kunye nendlela yokwenza. Izilingi eziphothiweyo zinika amandla aphezulu kunye nokuguquguquka. Iigrommets zibonelela ngomthamo owongezelelweyo. Ngalo lonke ixesha bhekisa kumenzi obekiweyo womthwalo obekiweyo, njengoko uphendula le miba.

5. Inyathelo ngeNyathelo Sling Umthamo wokubala

umzekelo: Kwi-1-intshi ye-IWRC sling (MBL 25,000 lbs), SF 5, kwi-angle ye-60 ° ethe tye, i-Adjusted WLL imalunga ne-4,330 lbs.

6. Imisebenzi yoKhuseleko ebalulekileyo kunye noLawulo lwe-Sling

6.1. Ukuhlolwa kokusetyenziswa kwangaphambili kunye nokuhlolwa kwamaxesha athile

Umntu onobuchule kufuneka azijonge ngeliso lengqondo izilingi yonke imihla phambi kokuba zisetyenziswe. Ukuhlolwa kwamaxesha athile nako kuyafuneka: ngonyaka kwinkonzo eqhelekileyo, ngenyanga ukuya kwikota yenkonzo eqatha. Khangela: Ithegi ye-ID elahlekileyo / engafundekiyo, iingcingo ezaphukileyo (imida ethile iyasebenza), i-abrasion enzima, i-kinking, ukutyumza, i-bird-caging, umonakalo wobushushu, i-cracked / i-deformed / i-attachments ekupheleni egugileyo, i-corrosion enzima, ukunciphisa ububanzi (> 5%), okanye i-waviness egqithisileyo (> 110%). Njalo susa izilingi ezonakeleyo ngokukhawuleza.

6.2. Iikhrayitheriya zokuSuswa kwiNkonzo

Nasiphi na isilingi esonakeleyo okanye esineziphene masisuswe ngoko nangoko enkonzweni. Ayinakubuyiselwa de ivunywe ngumntu oqeqeshiweyo emva kokulungiswa. Intambo yocingo ngokwayo ayinakulungiswa; kuphela iziqhoboshelo/izifakelo ezinokuthi zilungiswe, kwaye izilingi ezilungisiweyo mazimakishwe. Ukusebenzisa izilingi ezonakalisiweyo, nokuba "zibonakala" zanele, kukuphulwa kokhuseleko olungenakuxoxwa.
