Hāʻawi ʻo YT28 i ka hana kaulike ma ka pōhaku paʻakikī waena

He pilikia mau ka pōhaku paʻakikī waenahana ʻeli ʻanaa me nā hana tunneling, a me kekahiwiliE haʻi aku ka poʻe hana ma ke kahua iā ʻoe i ka paʻakikī o ka loaʻa ʻana o kahi mea hana e kaulike ai i ka mana a me ka hoʻohana lōʻihi. ʻO ia ke kumu i kūkulu ai mākou i ka YT28 pneumaticwili pōhaku wāwae ea— ua hoʻonohonoho ʻia me ka ikehu hopena kūpono no kēia mau kūlana pōhaku waena, e ʻeli ana i ka maʻemaʻe a me ka wikiwiki me ka ʻole o ka puhi ʻana i nā ʻāpana i ka wā mua. He loea mākouʻeli pōhakuhale hana mīkini, me nā makahiki o ke kūkulu lima ʻana a me ka hoʻāʻo ʻana ma ke kahua ma hope o mākou, a ua hana mākou i ka YT28 no ka pōhaku paʻakikī waena (paʻakikī F8-18) e lawelawe i nā lua wili maʻamau 32mm a 42mm, e hōʻea ana i ka hohonu kiʻekiʻe o 5 mika no nā hopena kūpaʻa a hilinaʻi hoʻi ma hope o ka neʻe ʻana. Hana kēia wili ma nā ʻano ʻelua: paʻa lima no nā wahi paʻa, a i ʻole i kau ʻia i kahi wāwae ea, e hui pū ana me nā wāwae pōkole FT160BC a me nā wāwae lōʻihi FT160BD e kūpono i nā tunnels mine haiki, nā alo tunnel a me nā wahi wili sloped me ka ʻole o ka pilikia. Hele mai ia me kahi mana maʻalahi, hoʻokahi lima-wai ea, ka lubrication aunoa mai ka FY200B oiler, a me nā hoʻoponopono wāwae ea wikiwiki e mālama i ka hana o kēlā me kēia lā i maʻalahi a pololei. E kamaʻilio kākou e pili ana i nā mea kahiko i hoʻohana ʻia e ka hapa nui o nā mines: maʻamau maʻamauwili pōhakuʻO nā hiʻohiʻona wāwae ea palupalu a palupalu i huki i ko lākou mau wāwae, hoʻonele i nā tona o ka ea i hoʻopaʻa ʻia, haki i ka maʻamau, a waiho i nā mea hoʻohana i luhi i ka hopena o ka hoʻololi. Hoʻoponopono ka YT28 i kēlā mau hemahema a pau: hōʻemi ia i ka hoʻohana ʻana i ka ea ma kahi o 15%, wikiwiki i ka holomua o ka ʻeli ʻana ma 20%, hoʻolōʻihi i ke ola o ka ʻāpana ʻaʻahu, a hoʻopau i ke kākoʻo wobbly a me ka hama ʻole i hoʻolilo i nā ʻeli kahiko i mea hoʻoluhi. He lawa ka maʻalahi e lawelawe i ka hana ʻeli honua, ka ʻeli ʻana i ke tunnel, ka hana mālama wai a me ke kuʻi ʻana i ke alaloa.

I kūkulu ʻia e lawe i ka lepo, ka haʻalulu a me nā kūlana ʻino o nā lua eli ma lalo o ka honua a me nā lua hāmama, ʻo kaYT28he 26kg wale nō ke kaumaha — he māmā ia e pale aku ai i nā mea hana mai ka luhi ʻana i nā manawa lōʻihi, akā ua lawa nō ka ikaika e hāʻawi i ka mana e pono ai no ka hana. Ua hoʻohui mākou i kahi muffler i kūkulu ʻia e hōʻemi i ka walaʻau o ka wahi hana, e hoʻolilo ana i ka wahi hana i palekana a ʻoi aku ka maʻalahi no nā limahana, a ua kūlike ia me nā kūlana palekana honua no ka hana mining a me ke kūkulu ʻana. Hele kēlā me kēia ʻāpana YT28 i nā nānā hale hana koʻikoʻi no ka paʻa o ke kaomi ea, ka hana hopena paʻa a me ka ikaika kūkulu paʻa, me ka hoʻohana ʻana i nā ʻāpana kūloko i hoʻoheheʻe ʻia e paʻa ana i ka hoʻohana nui ʻana i kēlā me kēia lā a hōʻemi i ka manawa downtime i hoʻolālā ʻole ʻia — he lanakila nui no nā mines e hana ana ma nā papa hana paʻa a me nā kālā paʻa.
