The Hidden Threat: Engvangin Nge Internal Fiber Damage hi Surface Wear aiin a pawimawh zawk

Rigging supervisor chuan hman hmaa enfiahna (routine) a ti thin. Chumi lifting belt chu  a tha hle—a cut lo, abrasion a awm lo, hmuh theiha a wear lo. A hman theih nan a pawm a ni. Darkar hnih hnuah sling hi mid-lift-ah a hlawhchham a, ton 3 zeta rit steel beam a tla thla ta a ni. Investigation-ah hian a chhan a lang: internal fiber chhiatna, tumahin an hmuh theih loh.

He scenario hi hypothetical a ni lo. Kum tin workshop leh construction site-ah a khel thin a, rigging safety lama thudik bulpui tak a tarlang bawk: i hmuh theih loh chuan a ti na thei che a ni. For synthetic lifting belts , internal fiber chhiatna hi surface wear zawng zawng aiin a hlauhawm zawk fo thin a, a chhan chu a chhiatna hun thlenga hmuh theih lohvin a awm reng vang a ni.
