Breaking chakna tehkhin dan (Diameter & Material Grade inang) .
Rope diameter inang, steel material, tensile grade leh manufacturing standard inang hnuaiah: 7×7 wire rope hian 7×19 aiin breaking load a nei sang zawk (a chak zawk).
Chhan:
1. Wire pakhat thickness danglamna
7×7 hian individual steel wire thick zawk a hmang a. Wire thick zawk hian wire khatah tensile force lian zawk a phur a, inner wire inkara contact surface friction loss a tlem zawk.
7×19 hian ultra-fine wire a hmang a; wire contact point tam zawk chuan tension hnuaiah internal friction nasa zawk a siam a, chu chuan overall ultimate breaking force a tihtlem phah a ni.
2. Cross-section hmanga metal area tangkai tak
Pawn lam diameter inangah chuan 7×7 hian wire thuk tak takte inkarah gap te zawk a hnutchhiah a, chu chuan effective steel cross-section lian zawk a siam a ni. Metal area lian zawk hian direct-in tensile breaking strength a ti tha zawk.
Data Reference Entirna (304 stainless steel hmanga siam wire rope hmanga siam a ni, Ø3mm) a ni.
7×7 Ø3mm: Min breaking load ≈ 880 kgf a ni
7×19 Ø3mm: Min chhe thei load ≈ 720 kgf

Hriat nawn tirna pawimawh tak tak Supplementary
- Rope pahnih hi diameter a inang lo a nih chuan: Diameter lian zawk hian breaking strength a nei sang zawk fo thin a, hei hian 7×7 strength advantage a override a ni.
- Material grade hi a pawimawh hle: 316 stainless steel, galvanized carbon steel, high-tensile alloy steel te hian a sak danah pawh a chakna nasa takin a thlak danglam thin.
- Working load safety factor: 7×7 hi chak zawk mahse, actual working load hian working weight aiin a let 5~10 vel safety factor a reserve tur a ni a, breaking load hi allowable load atan hmang ngai suh.
Diameter inang leh steel material inang nei:
Static tensile chakna chu:7×7 > 7×19 a ni
Flexibility & bending hahna dam chhung:7×19 > 7×7 a ni
Selection logic: Fixed heavy tension atan 7×7 hi dah pawimawh ber; pick 7×19 chu dynamic bending & winding hnathawhna hmun atan.
