Flat Sling Retire dan tur 1/10 Rule chu eng nge ni?

Rigging supervisor pakhat chuan a enfiah a flat sling .  thla engemaw zat service-a awm tawh A sir lam chu a chhe deuh a, a chung lamah pawh abrasion engemaw zat a lang bawk. Sling chu ni ṭha zawk hmu tawh ang maiin a lang—mahse, hman a la him em?

 

A chhanna chu dan awlsam takah a awm a: 1/10 dan. EN 1492-1, European standard for flat woven webbing slings ang chuan, abrasive wear hian webbing zau zawng chu a zau zawng hmun sawma ṭhena hmun khat emaw a aia tam emaw a tihhniam chuan, sling chu service aṭangin lak chhuah nghal a ngai a ni ASME B30.9 pawhin chutiang bawkin abrasive wear tam lutuk—sling cross-section tihtlem emaw, core yarns pholang thei emaw—chu chu pension ngai condition atan a pawm a ni.

 

Lishenflex hian  kum sawmhnih chuang zet chu synthetic flat slings an siam tawh a, kan field data atanga a lan dan chuan abrasion hi sling retirement chhan ber pakhat a ni. Mahse, rigger tam tak chuan engtikah nge wear hi 'excessive.' tih hriat tumin an bei nasa hle. 1/10 rule hian threshold chiang tak, teh theih a pe a ni.

 

1/10 Rule chu eng nge ni?

1/10 rule chuan abrasive wear hian webbing zau zawng chu a zau zawng aiin 1/10 emaw a aia tam emaw a tihhniam chuan flat sling chu service atanga lakchhuah a ngai tih a sawi.

 

A taka hman chuan hei hi a awmzia chu:

 

Thu lakna: EN 1492-1; ASME B30.9 a ni

 

He dan hi abrasive wear -ah  chauh hman a ni—cut, tear, a nih loh leh chhiatna chi dang a ni lo. Mahse, 1/10 threshold chu wear leh damage dang inzawmkhawm hmanga thlen a nih chuan sling chu retired a la ngai tho.

 

Engvangin nge 1/10 Rule hi a awm?

1/10 threshold hi duhthusam a ni lo. Industry testing data atanga a lan dan chuan 10% edge cut hian sling capacity 35% in a tihhniam thei a ni . 1/10 rule hian abrasive wear (cut aiin) a buaipui ber laiin, principle chu a inang vek a ni: webbing zau zawng 10%-a tihhniam a nih chuan sling chakna chu nasa takin a tlahniam a ni.

 

EN 1492-1  standard chuan flat woven webbing slings te chu abrasive wear a awm leh awm loh enfiah a ngai tih a tarlang a, chu chuan webbing chu a original width tihtlem thlengin a tichhia a ni. ASME B30.9 pawhin chutiang bawkin slings abrasive wear tam lutuk chu service atanga paih chhuah a ngai a ni.

 

Lishenflex’s lab testing chuan abrasion avanga slings 10% width reduction nei te hian breaking strength teh theihin a tlahniam tih a nemnghet a—a tlangpuiin wear pattern a zirin 15–25% a ni. Hei vang hian 1/10 rule hi safety threshold pawimawh tak a ni.

 

Webbing Width teh dan

1/10 rule dik taka hman tur chuan tehna dik tak a pawimawh hle.

 

Thil hmanrua mamawh

 

• Millimeter graduation neia tehna tape emaw ruler emaw

• Calipers hmanga tehna dik zawk (borderline case tan a tha ber)

• Edge wear enfiahna tur magnifying glass (optional) a ni

 

Measurement tih dan tur

 

1. Sling-a a chhe ber lai chu thlang rawh—a tlangpuiin sling sei zawng lai takah emaw, load emaw, lifting hardware emaw nena inzawmna hmunah emaw

 

2. Original width chu teh rawh—sling-a identification tag emaw, siamtu specification emaw en rawh. Original width a awm loh chuan sling khata unworn section chu teh rawh

 

3. Worn width chu teh rawh—wear area hmun tawi ber ah

 

4. Wear = Original zau zawng − Worn zau zawng chhut rawh

 

5. Percentage chhut rawh = Wear ÷ Original zau zawng × 100%

 

6. 1/10 rule hmang rawh—original width ≥ 10% i ha chuan sling chu retire rawh

Point pawimawh tak tak te

 

• A zau zawng zawng chu teh rawh—a thuk ber lai chauh ni lovin

• Point hrang hrangah teh rawh—wear chu a inthlau thei

• I tehnate chu ziak chhuak rawh—ASME B30.9 thil mamawh angin inspection record vawng reng rawh

 

Hriatthiam lohna tlanglawn tak tak

Ngaihdan dik lo awm fo engemaw zat chuan 1/10 dan hman dik lohna a thlen thei a ni:

 

ASME B30.9-in a tarlan dan chuan abrasive wear tam lutuk chu core yarn-te pholang emaw, sling cross-section tihtlem emaw, wear tihna a ni. ASME B30.9-ah erawh chuan '1/10' chu chiang takin chutiang bawk chuan a sawi lo thung EN 1492-1  chuan a ti a, standard chuan wear chu core exposed emaw cross-section tihtlem emaw a thlen chuan sling chu retired a ngai tih a pawm a ni.

 

EN 1492-1 erawh chu a chiang hle: abrasive wear-in webbing zau zawng 1/10 emaw a aia tam emaw a tihtlem chu service atanga lakchhuah nghal theihna tur condition a ni.

Flat Slings atana Retirement Criteria dangte

1/10 rule hi retirement criteria hrang hrang zinga pakhat a ni. ASME B30.9 ang chuan flat slings pawh hi retire a ngai a, chu chu:

 

• Identification tag awm lo emaw chhiar theih loh emaw

• Acid emaw caustic emaw hmanga kang

• Khua lumnain a tichhia tih finfiahna—melt, charring, a nih loh leh blistering

• Core yarns pholang thei tur holes emaw tears emaw

• Load-bearing splice-a stitching chhe emaw, chhe tawh emaw

• Sling taksaah knots a awm

• Coloration leh brittle emaw stiff area te chuan chemical emaw UV/sunlight emaw a tichhia tih a tilang

• Fittings pitted, corroded, cracked, bent, twisted, emaw chhe tawh te

 

EN 1492-1 angin, webbing chhunga lut cutting damage emaw, load-bearing capacity tichhe thei seam damage emaw a awm chuan flat slings pawh hi retire tur a ni.

 

Practical taka hman theih a ni

1/10 rule hi hman reng a nih theih nan:

 

1. I team te chu zirtir rawh—rigger leh supervisor zawng zawngte chuan webbing zau zawng teh dan dik tak an hriat theih nan

 

2. Measure dik tak atan caliper hmang rawh—tape measures hi variation tenau te tan chuan a dik lo thei

 

3. Document enfiahna—original width leh measurement date tarlanna record vawn

 

4. Zawhna awm thei sling-te chu chhinchhiah rawh—nluk zawka enfiah theih nâna ramri nei sling-te chu chiang takin chhinchhiah rawh

 

5. Retire nghal rawh—wear 10% a thlen chuan sling chu service atangin la chhuak la, tichhia rawh

 

Thupui tawi leh Thurawn tangkai tak tak

1/10 rule hian abrasive wear avanga flat slings retire theihna tur threshold chiang tak, teh theih a pe a ni. Webbing zau zawng chu a zau zawng atanga 10% aia tam tihhniam a nih chuan sling chakna a tlahniam a, service atanga lak chhuah a ngai a ni.

 

Takeaway pawimawh tak tak:

 

1. Webbing zau zawng dik takin teh rawh—a dik taka tehna atan caliper hmang rawh

 

2. 1/10 rule hmang rawh—original width ≥ 10% hak = pension nghal

 

3. Inspection criteria dangte nen inzawm khawm la—1/10 rule hian abrasion a sawi a, mahse damage chi dangte pawhin pension a ngai bawk

 

4. Document enfiahna result—ASME B30.9 mamawh angin record vawn

 

5. I team chu zirtir rawh—mi zawng zawngin dan chu dik taka an hman theih nan enfiah rawh
