I ka ulu mau ʻana o ke kūkulu ʻana a me ka mining, ʻoi aku ka nui o ka koi no nā mīkini kūpono a hilinaʻi. ʻO kēia kahi o Sunward, he alakaʻi honua i nā mea hana ʻenekinia mai kona hoʻokumu ʻia ʻana i ka makahiki 1999, e komo pū me kāna mau ʻōnaehana quarrying rig hou. Ua hoʻokumu ʻia e Polofesa He Qinghua, he mea hoʻonaʻauao koʻikoʻi me ka paʻa paʻa i ka hana hou, ua kālai ʻo Sunward i kahi kūlana koʻikoʻi ma ka ʻoihana. ʻIke ʻia ka ʻoihana ʻaʻole wale no kāna mau huahana kiʻekiʻe akā no kona kūlana mākeke ikaika, e paʻa ana i ka mahele mākeke helu ʻekahi no nā rig wili pōhaku ma Kina.
Hoʻolālā ʻia nā rigs quarrying o Sunward e hoʻokō i nā koi koʻikoʻi o ka ʻoihana quarrying. Hāʻawi ka hui i kahi ʻano mea kupanaha o nā huahana, me ka SWDF200, SWDE165, SWDE120S, SWDA165C, SWDQ120, a me SWDE165A. ʻO kēlā me kēia o kēia mau hiʻohiʻona i hana ʻia e hāʻawi i ka hana ʻoi aku ka maikaʻi, ka lōʻihi, a me ka maikaʻi, e hōʻoiaʻiʻo ana e kū lākou i nā pilikia e kū nei i nā mea hana quarry. Kūkulu ʻia kēia mau rigs i mea e hoʻonui ai i ka huahana a hoʻomaʻamaʻa i nā hana, ʻo ia ka mea koʻikoʻi i ka honua hoʻokūkū nui o ka quarrying.
He rig quarrying ikaika ka SWDF200 e hōʻike ana i ka hoʻolaʻa ʻana o Sunward i ka maikaʻi a me ka hana. Me ka ʻenehana kiʻekiʻe a me ke kūkulu paʻa ʻana, kūpono kēia ʻano hoʻohālike no nā noi kaumaha, e hāʻawi ana i ka ikaika e pono ai no nā hana quarry paʻakikī. Hāʻawi pū nā hiʻohiʻona SWDE165 a me SWDE120S i ka versatility ʻokoʻa, e mālama ana i nā pono quarrying like ʻole me ka hōʻoia ʻana i ka pono o ka hana. Hoʻolālā ʻia kēia mau rigs e hōʻemi i ka manawa haʻahaʻa a hoʻonui i ka huahana, he mea nui ia no kēlā me kēia hana quarry.
Hāʻawi pū ʻo Sunward i ka SWDA165C, he kumu hoʻohālike e hoʻohui i ka ʻenehana hou me ka hoʻolālā ergonomic. ʻAʻole hoʻomaikaʻi wale kēia rig quarrying i ka huahana akā ʻoi aku ka mua o ka hōʻoluʻolu o ka mea hana, ʻo ia ka mea nui i ka hana o kēia mau lā. ʻO ke kumu hoʻohālike SWDQ120 he mea hoihoi loa ia, e hoʻokiʻekiʻe ana i nā hiʻohiʻona e hoʻomaikaʻi i ka hana me ka mālama ʻana i ka hilinaʻi i nā kūlana koi. ʻO ka mea hope loa, hoʻopau ka SWDE165A i ka waihona o Sunward, e hāʻawi ana i kahi hopena paʻa no nā mea hana e ʻimi nei i ka pono me ka ʻole o ka hoʻohālikelike ʻana i ka maikaʻi.
Ke hana nei ka hui me ka manaʻo nui i ka noiʻi a me ka hoʻomohala ʻana, i alakaʻi ʻia e ka ʻike ʻo Professor He. ʻIke ʻia ke kūpaʻa o Sunward i ka hoʻoulu ʻana i nā mea hou i kāna mau huahana, e koi mau ana i nā palena o nā mea hiki i ka ʻāpana ʻeli. Hoʻokumu kēia hoʻolaʻa iā Sunward ma ke ʻano he hoa hilinaʻi no nā ʻoihana e ʻimi nei e hoʻolako iā lākou iho me nā mea hana maikaʻi loa no kā lākou hana ʻana.
I ka hopena, hōʻike nā rigs quarrying a Sunward i ka hui kūpono o ka ʻenehana, hilinaʻi, a me ka pono. ʻO kā lākou nui o nā huahana, me ka SWDF200, SWDE165, SWDE120S, SWDA165C, SWDQ120, a me SWDE165A, e hōʻoia ana inā ʻoe e hana i ka ʻeli ʻana i ka ʻāina a i ʻole ka ʻeli ʻana i lalo o ka honua, aia kahi mīkini i hoʻonohonoho pono ʻia i kāu mau pono. Ke piʻi mau nei ka noi no ka hoʻoponopono ʻana i ka ʻeli ʻana, ua mākaukau ʻo Sunward e alakaʻi i ke ala, e hāʻawi ana i nā lako hana kiʻekiʻe e kū ana i nā pilikia o ka quarrying head-on. No ka poʻe i loko o ka ʻoihana, ʻo ke koho ʻana iā Sunward, ʻo ia ka hoʻopukapuka ʻana i ka maikaʻi a me ka hana hou no ka wā e hiki mai ana i ka hana ʻana i ka ʻili.
