ʻO kahi puʻu alahaka ma lalo, ʻike ʻia hoʻi ʻo ka crane under-running bridge crane a i ʻole underslung bridge crane, kahi ʻano o ka crane overhead e hana ana ma kahi ʻōnaehana holo kiʻekiʻe. ʻAʻole e like me nā cranes ma luna o ke poʻo maʻamau e holo ana ke kāʻei alahaka ma luna o nā kaola alahaka, ʻo ka crane ma lalo o ke kau ʻana i ke alahaka e holo ana ma lalo o nā kaola alahaka. Eia kekahi mau kikoʻī a me nā hiʻohiʻona o nā cranes underhung bridge:
Hoʻonohonoho ʻia: ʻO nā puʻu alahaka ma lalo o ka mea maʻamau i loko o ke kaʻa alahaka, nā kaʻa hope, ka hui hoist/trolley, a me kahi ʻōnaehana holo. ʻO ke kāʻei uwapo, ka mea e lawe ana i ka hoist a me ka trolley, ua kau ʻia ma nā ʻaoʻao lalo o nā kaola holo.
Pūnaehana Runway: Ua kau ʻia ka ʻōnaehana holo ma luna o ka hale kūkulu hale a hāʻawi i kahi ala no ka crane e hele ai i ka pae. Loaʻa iā ia he ʻelua mau kaola holo ala like e kākoʻo ana i ke kāʻei alahaka. Hoʻokuʻu pinepine ʻia nā kaola holo kaʻa mai ka hale kūkulu hale me ka hoʻohana ʻana i nā hangers a i ʻole brackets.
Kākoʻo Alahaka: ʻO ke kāʻei alahaka ka lāʻau ākea e hoʻopaʻa ana i ke āpau ma waena o nā kaola holo. Ke neʻe nei ia ma ka ʻōnaehana holo me ka hoʻohana ʻana i nā huila a i ʻole nā wili i kau ʻia ma nā kaʻa hope. Kākoʻo ke kāʻei uwapo i ka hui hoist a me ka trolley, e neʻe ana ma ka lōʻihi o ke kāʻei alahaka.
Hoist and Trolley Assembly: ʻO ka hui hoist a me ka trolley ke kuleana no ka hāpai ʻana a me ka neʻe ʻana i nā ukana. Loaʻa iā ia kahi hoist uila a lima paha i kau ʻia ma kahi trolley. Holo ka kaʻa ma ke kaʻe o ke alahaka, e ʻae ai i ka hoist e hoʻonoho a lawe i nā ukana ma waena o ka wahi hana.
Hiki ke hoʻololi: Hāʻawi nā cranes bridge underhung i ka maʻalahi e pili ana i ka hoʻonohonoho ʻana a me ka hoʻohana ʻana. Hoʻohana pinepine ʻia lākou i nā keʻena kahi i kaupalena ʻia ai ke keʻena poʻo a i ʻole hiki i nā hale e kū nei ke kākoʻo i ke kaumaha o kahi crane ma luna. Hiki ke hoʻokomo ʻia nā cranes underhung i nā hale hou a i ʻole i hoʻopaʻa hou ʻia i loko o nā hale e kū nei.
Mea Hana Hana: Hoʻohana pinepine ʻia nā cranes underhung i nā hale hana e hoʻoneʻe i nā mea maka, nā ʻāpana, a me nā huahana i hoʻopau ʻia ma nā laina hui. Hāʻawi lākou i ka hoʻonohonoho pono a me ka pololei o nā mīkini kaumaha, nā mea hana, a me nā mea hana i ka wā hana.
Nā hale kūʻai a me nā kikowaena hoʻolaha: Hoʻohana ʻia nā cranes underhung i nā hale kūʻai a me nā kikowaena hoʻolaha e mālama a lawe i nā waiwai, pallets, a me nā ipu. Hoʻomaʻamaʻa lākou i ka neʻe ʻana o nā huahana i loko o nā wahi mālama, hoʻouka a hoʻoiho i nā kaʻa, a me ka hoʻonohonoho ʻana i nā waihona.
ʻOihana Kaʻa: He hana koʻikoʻi ka underhung cranes i ka ʻoihana kaʻa. Hoʻohana ʻia lākou no nā hana e like me ka hāpai ʻana a me ka hoʻonohonoho ʻana i nā kino kaʻa i ka wā o ka hui ʻana, ka neʻe ʻana i nā ʻāpana kaʻa kaumaha ma nā laina hana, a me ka hoʻouka ʻana a me ka hoʻoiho ʻana i nā mea mai nā kaʻa.
ʻOihana Aerospace: Ma ka ʻoihana aerospace, hoʻohana ʻia nā cranes underhung no ka mālama ʻana a me ka hui ʻana o nā ʻāpana mokulele nui, e like me nā ʻēheu a me nā fuselages. Kōkua lākou i ka hoʻonohonoho pololei a me ka neʻe ʻana o kēia mau ʻāpana kaumaha a palupalu, e hōʻoiaʻiʻo ana i nā kaʻina hana pono.
Hana Metala: Loaʻa pinepine ʻia nā cranes underhung i nā hale hana metala. Hoʻohana ʻia lākou no ka mālama ʻana a me ka lawe ʻana i nā ʻāpana metala kaumaha, nā kaola, a me nā mea hana ʻē aʻe. Hāʻawi ʻo Underhung cranes i ka hiki ke hāpai a me ka maneuverability no nā hana hana like ʻole, me ka wili, ʻokiʻoki, a me nā hana hana.
Loaʻa nā cranes ma lalo o ke poʻo i ka noi ma kahi ākea o nā ʻoihana a me nā kaiapuni kahi e pono ai ka lawelawe ʻana i nā mea waiwai a me nā hana hāpai ʻana.
