I ka lawelawe ʻana i nā mea, he mea hana ikaika a maʻalahi hoʻi ka gantry crane, e hoʻololi nei i ka lawelawe ʻana i nā ukana ma nā pā hale waho, nā awa, a me nā kahua kūkulu.
I. He aha ka Gantry Crane?
Loaʻa i kahi crane gantry kahi ʻōnaehana metala i hoʻohālike ʻia me ke ʻano gantry (e like me ka puka) me kahi kaola hāpai (girder nui) i kākoʻo ʻia e nā wāwae ʻelua. Neʻe kēia mau wāwae ma nā alahao honua, e hiki ai ke hele ākea. Loaʻa i kekahi mau hoʻolālā nā wēlau girder nui cantilevered no kahi laulā hana ākea.
II. Nā ʻAno o nā Gantry Cranes
1. Ma ke ʻano Gantry
Crane gantry piha: Paʻa, me ka ʻole o nā girder overhangs nui, kūpono no nā hana maʻamau i nā wahi paʻa.
Crane Semi-gantry: He ʻokoʻa ke kiʻekiʻe o nā wāwae, e hoʻololi ana i ka ʻāina ʻaʻole i kūlike ʻole a i ʻole nā hale i kū nei i nā hoʻonohonoho ʻoihana kūikawā.

2. Na Cantilever Design
ʻElua - cantilever Gantry Crane: ʻOi aku ka girder nui ma mua o nā wāwae ʻelua, e hoʻonui ana i ka hoʻohana ʻana i ka pūnaewele, kūpono no nā awa a i ʻole nā pā ukana nui.
Hoʻokahi - cantilever Gantry Crane: Hoʻonui hoʻokahi - hopena, kūpono no nā wahi i kaupalena ʻia e like me nā mea kanu haiki.
3. Ma o ke ʻano hana Girder nui
ʻO ke Crane Gantry girder hoʻokahi: Maʻalahi, haʻahaʻa ke kumukūʻai, me kahi ʻano pahu. Kūpono no nā ukana liʻiliʻi a waena (q ≤ 50t, s ≤ 35m), e laʻa, ma nā hale hana liʻiliʻi.
ʻO ke Crane Gantry girder pālua: Ikaika, ākea nui, paʻa. ʻO nā ʻano like ʻole:
a. Pahu - girder Crane: Kiʻekiʻe - palekana, nui - ʻoʻoleʻa, no nā hana kaumaha (e laʻa me nā hale hana moku), akā pipiʻi a kaumaha hoʻi.
b. Truss - girder Crane: Haʻahaʻa ke kumukūʻai, māmā, maikaʻi ke kū'ē ʻana i ka makani, akā pono e hoʻopili pinepine ʻia - nā nānā kiko, no nā ukana liʻiliʻi.
c. Honeycomb - girder Crane: Hoʻohui i nā hiʻohiʻona truss a me ka pahu, hilinaʻi, no nā wahi ukana pinepine a kaumaha paha (e like me nā pā hale kaola alahaka).

4. Ma o ka noi
General Gantry Crane: Hoʻohana ākea, lawelawe i nā waiwai like ʻole, hiki ke hāpai i ka hiki ma lalo o 100 tons, ʻākea 4 - 39m.
Ke Kahua Hoʻoulu Mana Wai: Hāpai i nā puka pā, hoʻokomo, hiki ke halihali i 80 - 500 tons, ʻāpana liʻiliʻi (8 - 16m).
Crane Gantry Hana Moku: Hoʻākoakoa i nā kino o ka moku, hiki ke hana i 100 - 1500 tons, ʻākea nui (a hiki i 185m).
Crane Gantry Pahu: Nā pahu hoʻouka/hoʻouka, alahao a i ʻole ka laholio - luhi, papa hana kiʻekiʻe, hiki ke piʻi a hiki i ka 60m.
III. ʻAno a me ke Kumumanaʻo Hana
1. Nā ʻĀpana Nui
ʻO ke kinikini Gantry: Hana ʻia ke kila, hoʻohui i nā girders nui no ke kūpaʻa.
Kaula Nui: Kaula kila, i hoʻonui ʻia e ka ukana a me ke alapine (pinepine).
ʻAno Hana Hāpai: Hoʻokomo pū ʻia ka motika, ka mea hoʻēmi, a me nā mea ʻē aʻe, e kaohi ana i ka hāpai ʻana.
ʻAno Hana Huakaʻi: Loaʻa nā huila, ka motika, hoʻoneʻe i ke crane.
ʻAno Hana Huakaʻi Trolley: Hoʻoneʻe i nā ukana ma o ka motika, nā kaula, a pēlā aku.
ʻŌnaehana Mana Uila: Nānā a kāohi i nā hana.
2. Kumu Hana
Hoʻoneʻe ka mea hoʻohana i ka crane i kona wahi.
Hiki i ka Trolley ke hopu a hāpai i nā waiwai.
Hoʻoneʻe ka ʻenekini huakaʻi i ke kaʻa i hoʻouka ʻia.
Hoʻokomo ʻo Trolley i nā waiwai i ka wahi i hele ʻia.
IV. Nā Pōmaikaʻi a me nā Pōʻino
1. Nā Pōmaikaʻi
Hoʻohana Kiʻekiʻe ʻana i ka Paena: Holo kaʻaahi, ʻaʻohe pilikia o ka huila/mea hana mīkini hana, hoʻohana pono i ka hakahaka.
Ka laulā hana nui: Uhi nā cantilevers a me ka neʻe ʻana o ke kaʻaahi i nā wahi ākea.
Hiki ke hoʻololi ikaika: Hiki ke hoʻopilikino ʻia i nā wahi/pono (e laʻa, semi-gantry no ka ʻāina ʻaʻole like).
Hana kūpono: Hoʻokele ʻia e ka uila, mālama haʻahaʻa, hiki ke mālama i ka ikehu.
ʻOihana Hana Kiʻekiʻe: Ka lawelawe pololei ʻana ma o nā ʻōnaehana kaohi a me ke kūlana.
2. Nā hemahema
Ke aniau - Hiki ke maʻalahi: ʻO ka hoʻohana ʻana ma waho e pilikia i ka popo (mai ka ua) a me ka paheʻe/kahuli (mai ka makani), e pono ai nā hana palekana.
Kahua - Hilinaʻi: Hilinaʻi i nā alahao; ʻo ke kau ʻana/hoʻoponopono ʻana i nā alahao he pono ke kumukūʻai a me ka manawa.
Hoʻopukapuka mua kiʻekiʻe: He pipiʻi ke hoʻolālā, hana ʻana, a me ke kau ʻana, ʻoiai no nā crane nui a kūikawā paha.
V. Nā Kahua Noi
Hana nā gantry cranes:
ʻEnekinia Hydraulic: Kūkulu/mālama i nā pā wai, nā laka moku, hāpai i nā ʻīpuka.
Kūkulu ʻana: Hana/hoʻokomo i nā mea kūkulu hale ma nā hale kiʻekiʻe a me nā alahaka.
Hana ʻana: E hōʻuluʻulu i nā ʻāpana hana nui i nā mīkini, nā ʻoihana kaʻa.
Petrochemical, Mining, Shipbuilding: Hoʻoneʻe i nā lako kaumaha, nā mea maka.
Nā awa: Hoʻouka/wehe i nā ipu, nā ukana nui.
TʻO ke gantry crane, me nā ʻano like ʻole, ke kūkulu paʻa, a me ka hoʻohana ākea, he kī ia i ka lawelawe ʻana i nā mea hou. ʻOiai nā palena, hoʻonui ka hana hou i kāna hana, e kōkua ana i ka pono o ka ʻoihana.
