Metala Forensics: Hoʻokaʻawale i nā hōʻailona Silent o ka luhi ʻo Wire Rope

I loko o ke ao o ka haʻi kaumaha, ʻo ka noho mālie ka ʻōlelo aʻo weliweli loa. ʻOiai ke nānā aku nei nā kuʻina palekana maʻamau i nā "uwea haki" o waho, ʻike ʻia ke ola maoli o ke kaula uwea kila i loko o kona kumu-kahi aupuni i hūnā ʻia mai ka ʻike maka. Ma kaSOLITE, mālama mākou i ka palekana ʻaʻole ma ke ʻano he papa kuhikuhi, akā ma ke ʻano he ʻepekema forensic.

1. ʻO ka Pulse ʻIke ʻole: Ma waho aʻe o ka Maka olohelohe

ʻO ka nānā ʻana, ʻoiai he mea nui, hōʻike wale i ka 20% o ka pono o ke kaula. No ka hoʻokō aZero, hoʻohana ʻenehana houKa Leʻaleʻa Mākēneki (MFL). Ma ke kau ʻana i ke kaula ma waena o ka -saturation mākēneki kiʻekiʻe, hiki i nā mea ʻike ke ʻike i nā "leaks" ma muli o ka haki ʻana o ka uwea kūloko a i ʻole ka poho metala kūloko. 'O kēia ka pu'upu'u o ke kaula-he ikepili-biography o kona ola lawelawe i koe.

2. Hoʻololi i ka "Rouge": ʻO ka ʻōlelo aʻoaʻo ʻulaʻula

Ua ʻike paha ʻoe i ka pauda ʻulaʻula -ʻulaʻula e puka mai ana mai nā kaula? Ma nā ʻōlelo loea, ʻo ia ka "fretting corrosion," i ʻōlelo pinepine ʻia ʻo iaʻulaʻula. ʻO kēia pauka ka hopena o nā kaula o loko e ʻānai ana kekahi i kekahi ma muli o ka lawa ʻole o ka lubrication a i ʻole ka luhi loa. He hōʻailona forensic ia e ʻai ana ka hale o loko o ke kaula iā ia iho mai loko mai.

3. ʻO ka wānana wānana: i ka manawa hea e hoʻomaha ai?

ʻO ka hoʻoholo ʻana i ka manawa kūpono o ka hoʻolei ʻana he hana no ka hoʻokele pilikia. Ma ka hui ʻanaE hoʻolei i nā Koina (ISO 4309)me ka ʻikepili MFL, kōkua ʻo SOLITE i nā ʻenekinia i ka wānana i ka "Safety Cliff"-ka wahi e wikiwiki ai ka luhi. ʻAʻole pili ka palekana i ka hoʻohana ʻana i ke kaula a haki; e pili ana i ka hoʻomaha pono ʻana i ka wā i hoʻokō ai kona ʻuhane i kāna hana.
