Hoʻohana mau ʻia nā cranes overhead i nā ʻoihana like ʻole no ka lawelawe ʻana a me ka neʻe ʻana i nā mea. Pono kēia mau cranes i kahi lako mana hilinaʻi e hana pono a palekana. Aia nā ʻano laina lako mana i loaʻa no nā cranes overhead, kēlā me kēia me kā lākou pono ponoʻī. Ma kēia ʻatikala, e kūkākūkā mākou i nā ʻano maʻamau o nā laina lako mana no nā cranes overhead.
1. Conductor Rail Systems: Hoʻokomoʻia kēiaʻano o ka mana ma luna o ke ala holo crane a hāʻawi i ka mana hoʻomau a hoʻopauʻole i ka crane. He mea maʻalahi ka hoʻokomo a mālama ʻana i nā ʻōnaehana kaʻa kaʻa a kūpono i nā noi kaumaha.
2. Nā Pūnaehana Festoon: Aia kēia ʻano lako mana me ke kaula a i ʻole ke kaulahao maʻalahi i hoʻokuʻu ʻia ma waena o ke ala holo crane a me ke alahaka a i ʻole kaʻa. He mea waiwai nā ʻōnaehana Festoon a hāʻawi i kahi hāʻina lako mana maʻalahi a hiki ke hoʻololi ʻia nonā cranes ma luna.
3. Cable Reel Systems: Ke hoʻohana nei kēia ʻano o ka mana i ka pahu puna puna i kau ʻia ma ke alahaka a i ʻole ka trolley e hāʻawi ai i ka mana o ka crane i kona neʻe ʻana ma ke ala holo. He lōʻihi loa nā ʻōnaehana uwea a koi aku i ka mālama liʻiliʻi, e lilo lākou i koho kaulana no nā noi kaumaha.
4. Insulated Conductor Bar Systems: ʻO kēia ʻano o ka mana lako i loko o kahi pahu conductor insulated i kau ʻia ma luna o ke ala holo crane, e hāʻawi ana i kahi lako mana palekana a hilinaʻi i ka crane. He mea maʻalahi ka hoʻouka a mālama ʻana i nā ʻōnaehana bar conductor insulated a hiki ke hoʻohana ʻia i nā wela wela a me nā wahi ʻino.
ʻO ka holoʻokoʻa, ke ʻano o ka laina lako mana i hoʻohana ʻia no kahiluna cranee hilinaʻi ʻia ma ka noi kikoʻī a me ka waihona kālā. Eia nō naʻe, he mea nui e koho i kahi lako mana hilinaʻi a palekana e hōʻoia i ka holo ʻana o ka crane me ka maikaʻi a me ka palekana. ʻO ka hope loa, hiki i ka lako mana kūpono ke hōʻoia i ka hana maikaʻi loa o ka crane, e kōkua ana i ka hoʻonui ʻana i ka huahana a hoʻemi i ka manawa hoʻomaha.
