ʻO nā cranes ʻoihana nā mea hana pono i ke kūkulu ʻana a me ka hana ʻoihana, a hiki iā mākou ke ʻike iā lākou ma nā wahi āpau ma nā kahua kūkulu. Loaʻa nā ʻano o nā cranes e like me nā hale nui, nā mīkini paʻakikī, nā ukana hāpai like ʻole, a me nā kaiapuni paʻakikī. ʻO kēia ke kumu i loaʻa ai i nā ulia crane ko lākou mau ʻano ponoʻī. Pono mākou e hoʻoikaika i nā mea palekana crane, hoʻomaopopo i nā ʻano o nā ulia crane a me ke kuleana o nā mea palekana, a hana i ka hoʻohana palekana.
ʻO ka mīkini hoisting kahi ʻano o nā lako kaʻa kaʻa, ʻo kāna hana nui ka hoʻopau ʻana i ka neʻe ʻana o nā mea kaumaha.

Hiki i kekahi mau mīkini hoʻokiʻekiʻe ke hana i kekahi mau hana kaʻina hana kūikawā i ka wā o ke kaʻina hana e hoʻokō ai i ka mechanization a me ka automation o ke kaʻina hana.
Hiki i nā mīkini hoʻokiʻekiʻe ke kōkua i nā kānaka i kā lākou hana o ka lanakila ʻana a me ka hoʻololi ʻana i ke ʻano, e hiki ai i ka huki ʻana a me ka neʻe ʻana o nā mea nui i hiki ʻole i ka wā ma mua, e like me ka hui ʻana o nā moku kaumaha, ka hoʻokiʻekiʻe holoʻokoʻa o nā hale kiaʻi kūlohelohe, a me ka hāpai ʻana o ka holoʻokoʻa. hale kila o nā wahi haʻuki, etc.
Ka hoohana ana ocrane gantryloaʻa i ka makemake makeke nui a me ka waiwai waiwai maikaʻi. Ua ulu wikiwiki ka ʻoihana hana mīkini hoʻokiʻekiʻe i nā makahiki i hala iho nei, me ka awelika o ka ulu ʻana o ka makahiki ma kahi o 20%. I ke kaʻina hana mai nā mea maka a hiki i nā huahana, ʻo ka nui o nā mea i lawe ʻia e ka hāpai ʻana a me nā mīkini lawe kaʻa pinepine pinepine a i ʻole haneli mau haneli o ke kaumaha o ka huahana.

Ke hoʻohana ʻia ka crane, e pau nā ʻāpana neʻe, e wehe nā pilina, e hōʻino ka ʻaila, a e ʻino ke ʻano metala, e hopena ana i nā pae like ʻole o ka degradation i ka hana ʻenehana o ka crane, ka hana waiwai a me ka hana palekana.
