ʻO nā mea hana uwea mīkini hana a Morteng, e like me nā pahu puna puna, nā pahu uila, nā ʻohi hale kiaʻi, nā apo uila, a me nā kaʻa uwea akamai, ua hoʻohālikelike ʻia no nā mea uila ʻoihana kaumaha ma nā mines, nā hale moku, a me nā pahu. ʻO ke koho ʻana o ka hoʻonohonoho hoʻonohonoho maikaʻi loa e pili ana i nā koi hana kikoʻī a me nā kikoʻī mea hana.
No nā mea ʻeli uila he ≤20t ke kaumaha, ʻoi aku ka poʻe i hana i nā hana maʻalahi i nā wahi paʻa, ʻo ka hoʻolālā o luna-waho e hōʻike ana i ka hui pū ʻana o ka hale kiaʻi hao a me ka reel puna. ʻO ka hale kiaʻi hao 2 - 3m - kiʻekiʻe, i hui pū ʻia me 15 - 20m - hale kiaʻi puana puna kiʻekiʻe, hāʻawi i kahi pahu puna puna 45 - mika. ʻO kēia hoʻonohonoho e hiki ai i ka excavator ke hana i loko o kahi anawaena kūpono o 20 - 30m a puni ka hale kiaʻi, e kūpono ia no nā hana ma nā keʻena koʻu haʻiki a i ʻole nā wahi paʻa paʻa kahi e koʻikoʻi ai ka pololei a me ka pono o ka lewa.
I ka wā e pili ana i nā mea ʻeli uila ma waena o 40 - 60t, ʻo ka hoʻolālā haʻahaʻa haʻahaʻa me kahi pahu uila i kau pololei ʻia ma ka excavator e hāʻawi i ka versatility. Me ʻelua uea - nā koho hoʻolālā — ka mana mamao lima no ka hana maʻalahi a me ka wili ʻakomi no ka holo kaʻa holo ʻole - hiki i nā mea hana ke uhi i kahi ākea o 100m. He kūpono kēia hoʻonā no nā hana ʻeli lua hāmama a me ka lawelawe ʻana i nā ukana nui ma nā uka paʻa, kahi e pono ai ka uhi ākea a me ka hoʻokele pono ʻana o ke kaula.
No nā mea ʻeli uila kaumaha ≥60t, ʻo ka hui haʻahaʻa-waho o ke kaʻa uwea a me kahi pahu puna e hōʻoia i ka hana pono. ʻO nā kaʻa uwea me nā mana o 200m, 300m, a i ʻole 500m, me kahi pahu puna puna 20 - 30m - hiki ke hana i nā hana ma kahi ākea 150 - 200m. ʻOi aku kēia hoʻonohonoho paʻa i nā papahana ʻeli nui ma nā mines a me ka lawelawe ʻana i nā ukana kaumaha ma nā awa nui, e hālāwai ana i nā koi o nā hana ʻoihana kiʻekiʻe. Ma ke koho ʻana i nā lako Moteng kūpono e pili ana i ke kaumaha o ka excavator a me nā hiʻohiʻona noiʻi, hiki i nā ʻoihana ke hoʻokō i ka pono a me ka palekana.
