Mea hoololi a me ke kokua

ʻO ka hana a ka mea hoʻololi kaʻa kaʻa e wehe a kau i ka huila.ʻO ka mea nui i haku ʻia me kahi kiʻi, kahi pā kaomi, kahi pahu kaomi, kahi pahu kākoʻo, kahi trolley hele a me kahi ʻōnaehana hydraulic.Ua hoʻonohonoho like ʻia kahi pahu aila kōkua ma nā ʻaoʻao ʻelua o ka pahu aila waena.Hoʻopili pololei ʻia ka pā kaomi me ka cylinder ʻaila waena.Ma o ka launa pū ʻana ma waena o ka pā kaomi a me ke kaʻa kaʻa hook ring, ua hoʻopau ʻia ka hana hoʻohemo ʻana i nā huila ma lalo o ka mana o ka ʻōnaehana hydraulic.

He kiʻekiʻe ka maikaʻi o ka hana a me ka hiki ke hoʻololi ʻia ka mīkini hoʻohemo ʻana i nā kaila, a ʻaʻole ia e hōʻino i ke kaʻa i ka wā o ka wehe ʻana.Hiki ke hoʻohana nui ʻia i ka wehe ʻana o nā kaʻa kaʻa nui i ka metallurgy, ka ʻoihana kemika, ka lanahu, ka mālama wai a me nā hana ʻē aʻe.
