ʻO ka ʻoihana huila i ka hana hou ʻenehana e like me ka mana hoʻokele, ma o ka huila oblique a me ka meridian ʻelua mau kipi ʻenehana, ua lawe mai i ka huila pneumatic i kahi wā hoʻomohala piha lōʻihi, ʻōmaʻomaʻo, palekana a akamai hoʻi, ua lilo nā huila mileage kiʻekiʻe, nā huila hana kiʻekiʻe i koho nui o nā huila ukana a me nā huila ohua, ua hoʻohana nui ʻia nā huila palekana a me nā huila akamai i nā kaʻa hoʻohiwahiwa kiʻekiʻe; Hoʻohana nui ʻia nā huila paʻa i nā kaʻa ʻoihana, nā kaʻa koa, nā mīkini kūkulu, nā kaʻa trailer awa a me ke kahua mokulele a me nā kahua ʻē aʻe ma lalo o nā kūlana paʻakikī e like me ka wikiwiki haʻahaʻa a me ke kaumaha kiʻekiʻe; Hoʻonui mālie ʻia nā ala rabber e hoʻohui i nā mea hōʻiliʻili, nā mahiʻai rotary, nā tractors, a me nā mea ʻē aʻe. ʻO nā mīkini mahiʻai ʻano crawler a me nā mīkini kūkulu ʻano crawler e pili ana i nā mea ʻeli, nā mea hoʻouka, nā bulldozers, a pēlā aku.

Nā ʻano ʻoihana

ʻO kaala laholioʻO ka mākeke i haku ʻia me ka mākeke kākoʻo hale hana mīkini holoʻokoʻa a me ka mākeke pani waihona. Ma waena o lākou, hilinaʻi nui ka mākeke kākoʻo i ka hana o nā mīkini kolo, a pili loa kona cyclicality i ke kaʻina hana hoʻomohala o nā kahua noi ma lalo, ʻo ia hoʻi nā mīkini mahiʻai he cyclical liʻiliʻi, a he cyclicality ikaika ko nā mīkini kūkulu hale no ka mea pili loa ia i ka hoʻopukapuka kālā ʻana i nā pono hana a me ka hoʻopukapuka waiwai paʻa. Hilinaʻi nui ka mākeke pani i ka nona omīkini kolo, a me ka hoʻonui ʻia ʻana o ka nui o ka loaʻa ʻana o nā mīkini a me ka hoʻolaha ʻana a me ka hoʻopili ʻana o nā kūlana hana hou aʻe, ua hoʻonui ʻia ke koi no nā huahana ala laholio. Ma keʻano holoʻokoʻa, ʻaʻohe ʻano cyclical maopopo o ka ʻoihana kaila laholio.

Nā ʻano kau o keala laholioʻO ka ʻoihana e pili nui ana i ke kau o ka ʻoihana mīkini ma hope. ʻAʻole ʻike ʻia ke kau o nā mīkini kūkulu hale, ʻoiai ʻo nā mīkini mahiʻai e hōʻike ana i kahi pōʻaiapuni kau me nā pae lūlū a me ka ʻohi ʻana o nā mea kanu. Ma ka mākeke kūloko, ʻo ka hapaha ʻelua a me ka hapaha ʻekolu o kēlā me kēia makahiki nā kau kūʻai kiʻekiʻe no nā ala mīkini mahiʻai. Ma ka mākeke Hikina Hema o ʻAsia, ʻo ka hapaha mua a me ka hapaha ʻehā o kēlā me kēia makahiki nā kau kūʻai kiʻekiʻe no nā ala mīkini mahiʻai. Ma keʻano holoʻokoʻa, ʻaʻole like ka mākeke honua no nā noi ma hope o ke kau, no laila ʻaʻole maopopo ke kau o ka ʻoihana ala rubber.
