I ke ao o ke kālai ʻana, ke kūkulu ʻana, a me ka ʻeli ʻana i nā lua pōhaku, kahi e ʻoi aku ai ka hilinaʻi ma mua o ka paʻakikī o kēia manawa, ke hoʻomau nei kahi papa kikoʻī o nā mea hana pneumatic i ke kumu o nā hana o kēlā me kēia lā. ʻO kaYT28, YT27, a meYT29Amoʻo o nā wili pōhaku wāwae pneumatic, meTPB40, TPB60, a meTPB90ʻO nā mea haki alanui, e hōʻike ana i nā makahiki he ʻumi o ka hana i hōʻoia ʻia ma nā wahi koi loa. ʻAʻole pili kēia mau mea hana i ka ʻenehana ʻālohilohi; e pili ana lākou i ka hoʻopau ʻana i ka hana, ka neʻe ʻana ma hope o ka neʻe ʻana, ma nā kūlana e hōʻino ai i nā lako paʻa ʻole.

 

Ua hana ʻia nā wili pōhaku YT-series no hoʻokahi kumu nui: ka wāwahi pono ʻana i ka pōhaku waena a paʻakikī. ʻO kā lākou ʻano hoʻolālā e pili ana i ka hopena piston ikaika, ka hana wāwae ea pololei, a me nā koi mālama liʻiliʻi. Hāʻawi ka wāwae ea hiki ke hoʻololi ʻia i ka ikaika hānai mau a me ke kākoʻo mea hoʻohana koʻikoʻi, e ʻae ana i ka wili pololei ʻana i nā ʻano like ʻole. ʻO ka YT28 ka mea e hele pinepine ai no ka hana kaulike a me ka pono, ʻoiai ʻo ka YT29A e hoʻopaʻa i kahi punch kiʻekiʻe no nā ʻano paʻakikī loa, abrasive. ʻO ko lākou interoperability ʻo ia hoʻi he hiki ke hoʻoili ʻia nā ʻāpana ʻokoʻa a me ka ʻike hana, e hōʻemi nui ana i ka downtime a me nā kumukūʻai hoʻomaʻamaʻa. Ma nā wahi lua pōhaku mamao a i ʻole nā ​​​​papahana tunneling kahi e palupalu ai nā ʻōnaehana hydraulic paʻakikī, e hoʻomau ka hana ʻana o kēia mau wili pneumatic, ʻo kā lākou leo ​​​​rhythmic kūikawā e hōʻike ana i ka holomua mau.

 

ʻO ka mea e hoʻokō ana i kēia mau mea hana ʻeli mua ʻo ia ka moʻo TPB o nā mea haki paving hana kaumaha. Hoʻokumu nā hiʻohiʻona TPB40, TPB60, a me TPB90 i kahi laina piha no ka wāwahi lua, ka wāwahi, a me ka hana ʻeli ʻana. ʻO ka TPB40, ma ke ʻano he mea hana waena, hāʻawi i kahi kaulike maikaʻi loa o ka mana a me ka maneuverability no ka wāwahi ʻana i nā papa sima a i ʻole ka wehe ʻana i ka overburden. Hoʻonui ka TPB60 no nā hana koʻikoʻi e like me ka wāwahi ʻana i nā pōhaku nui a i ʻole ka lepo hau, ʻoiai ʻo ka TPB90 e lawelawe ana ma ke ʻano he hale mana maoli, hiki ke ʻoki i nā poloka pōhaku nui i nui loa no nā mea wili mua. ʻO kēia kaʻina hana wāwahi lua, i kapa pinepine ʻia ʻo "popcorning," he mea koʻikoʻi no ka mālama ʻana i ke kahe mālie o nā mea mai ka maka o ka lua pōhaku a i ka hale hana hana.

 

ʻO ka hui pū ʻana ma waena o nā wili YT a me nā mea haki TPB e hana i kahi kahe hana ponoʻī a kūpono hoʻi. ʻO ka mea mua, hana nā wili YT i nā lua pahū i kau pono ʻia a i ʻole nā ​​​​​​ʻano wili no ka māhele ʻana. Ma hope o ka pahū ʻana a i ʻole ka unuhi mua ʻana, ua ʻoki pono ʻia nā pōhaku nui a me nā pōhaku nui ma kahi me ka hoʻohana ʻana i nā mea haki TPB. Hoʻopau kēia i nā bottlenecks, hoʻemi i ka pono no ka pahū mua hou ʻana, a mālama i nā kalaka halihali e neʻe ana. Aia ka nani o kēia ʻōnaehana i kona maʻalahi a me ke kahua i kaʻana like ʻia. Hana nā ʻano mea hana ʻelua ma ke kaomi ea ʻoihana maʻamau, ʻo ia hoʻi, hiki i kahi compressor ikaika hoʻokahi ke kākoʻo i kahi ʻauwaʻa holoʻokoʻa o nā wili a me nā mea haki.

 

No nā luna hoʻokele papahana a me nā luna kahua, hāʻawi kēia ʻōnaehana i ka maʻalahi o ka hana a me ka kaohi ʻana i ke kumukūʻai. ʻO ka maʻalahi o ka mīkini o kēia mau mea hana e ʻae ai i ka mālama ʻana a me ka hoʻoponopono ʻana ma kahi, e pale ana i nā kali lōʻihi no nā loea kūikawā. Eia kekahi, he mea kaulana ko lākou kūpaʻa; ʻaʻole ia he mea maʻamau ka loaʻa ʻana o nā wili YT a me nā mea haki TPB i ka lawelawe ma hope o nā makahiki he ʻumi o ka hoʻohana nui ʻana. I loko o kahi ʻoihana e kālele nui ana i ka huina kumukūʻai o ka nona, ʻo ka moʻolelo i hōʻoia ʻia, a me ka hilinaʻi paʻa o kēia mau mea hana pneumatic e hōʻoiaʻiʻo ana he ʻāpana koʻikoʻi lākou o ka ʻāina mining a me ke kūkulu ʻana o ka honua, e hoʻoikaika ana i nā hana e wehewehe ana i ke kuamoʻo o ka hoʻomohala ʻana i nā ʻoihana.
