ʻOi aku ka maikaʻi o ka hoʻomaopopo ʻana i ka hoʻokaʻawale ʻana o nā cranes gantry i ke koho a kūʻai ʻana i nā cranes. Loaʻa nā ʻano like ʻole o nā cranes. Ma lalo iho nei, e hōʻike ana kēia ʻatikala i nā hiʻohiʻona o nā ʻano cranes gantry i nā kikoʻī no nā mea kūʻai aku e hoʻohana ai i mea kuhikuhi i ke koho ʻana e kūʻai i kahi crane.
E like me ke ʻano o ke ʻano o ka crane frame
E like me ke ʻano o ka hoʻolālā ʻana o ka puka puka, hiki ke hoʻokaʻawale ʻia i ka crane gantry a me ka crane gantry cantilever.
ʻO nā cranes gantryua maheleia i:
1. Full gantry crane: ʻaʻohe overhang ka lāʻau nui, a neʻe ka trolley i loko o ke kiko nui.
2. Semi-gantry crane: E like me nā koi o ka hana kīwila ma ka pūnaewele, ʻokoʻa ke kiʻekiʻe o nā outriggers.
Hoʻokaʻawale ʻia nā cranes gantry cantilever i:
1. Palua cantilever gantry crane: kekahi o ka loa maʻamau structural palapala, kona structural koʻikoʻi a me ka pono hoʻohana 'ana i ka paena wahi ua kupono.
2. Single cantilever gantry crane: Ma muli o nā kapu kahua, koho pinepine ʻia kēia ʻano.
Hoʻokaʻawale ʻia e like me ke ʻano a me ke ʻano o ka beam nui o ka gantry crane:
1. Hoʻopili piha ʻia o nā cranes gantry girder nui
He ʻano maʻalahi ko ka crane gantry single-girder, maʻalahi e hana a hoʻokomo, a he liʻiliʻi liʻiliʻi. ʻO ka hapa nui o kāna mau kaola nui, he mau hale pahu pahu hao. Ke hoʻohālikelike ʻia me ka crane gantry double-girder, ʻoi aku ka nāwaliwali o ka ʻoʻoleʻa holoʻokoʻa. No laila, i ka wā e hāpai ana i ke kaumaha Q≤50 tons, ka span S≤35m.
Hoʻokahi pahu gantry craneLoaʻa nā wāwae puka i ka L-type a me C-type. He maʻalahi ka hoʻokomo ʻana o ke ʻano L-like, maikaʻi ke kūpaʻa ikaika, a he liʻiliʻi liʻiliʻi, akā liʻiliʻi ka wahi no ka hāpai ʻana i nā waiwai ma nā wāwae. Hoʻopili ʻia nā wāwae C-like a kūlou paha e hāʻawi i kahi ākea ākea nui no ka holo ʻana o ka ukana ma nā wāwae.
2. Hoʻopiha piha ʻana i nā cranes gantry girder nui pālua
ʻO nā cranes gantry pālualoaʻa i ka hiki ke lawe ikaika, nā ʻāpana nui, ke kūpaʻa holoʻokoʻa maikaʻi, a me nā ʻano like ʻole, akā ʻoi aku ka nui o kā lākou nui ma mua o nā cranes gantry single-girder me ka hiki ke hāpai like, a ʻoi aku ke kumukūʻai.
E like me nā ʻano hana ʻokoʻa nui, hiki ke hoʻokaʻawale ʻia i ʻelua ʻano: pahu pahu a me ka pahu. I kēia manawa, hoʻohana mau ʻia nā ʻano pahu pahu.
Hoʻokaʻawale ʻia e like me ke ʻano o ka beam nui o gantry crane:
1. ʻAi ʻaʻa ʻaʻa puʻu
ʻO ka hoʻolālā welded o ke kila kihi a i ʻole I-beam ka maikaʻi o ke kumukūʻai haʻahaʻa, ke kaumaha māmā a me ke kūpaʻa makani maikaʻi.
Eia nō naʻe, ma muli o ka nui o nā helu welding, loaʻa nā hemahema i ka truss ponoʻī. Loaʻa i ka truss beam nā hemahema e like me ka deflection nui, ʻoʻoleʻa haʻahaʻa, hilinaʻi haʻahaʻa, a me ka pono no ka ʻike pinepine ʻana i nā wahi wili. He kūpono ia no nā pūnaewele me nā koi palekana haʻahaʻa a me ke kaumaha hāpai liʻiliʻi.
2. pahu apo gantry crane
Hoʻopiliʻia nā papa kila i loko o ka pahu pahu, nona nāʻano o ka palekana kiʻekiʻe a me ka paʻakikī kiʻekiʻe. Hoʻohana maʻamau no nā tonnage nui a me nā tonnage gantry cranes nui. Hoʻohana ka lāʻau nui i ka hoʻolālā pahu pahu. Loaʻa i nā kaola pahu nā hemahema o ke kumukūʻai kiʻekiʻe, ke kaumaha make, a me ka maikaʻi ʻole o ka makani.
3. Honeycomb beam gantry crane
Ua kapa ʻia ʻo "isosceles triangle honeycomb beam", he triangular ka maka hope o ka lāʻau nui, a aia nā lua honeycomb ma nā ʻaoʻao ʻelua o ka ʻōpū oblique, luna a me lalo. Hoʻopili nā kaola kelepona i nā hiʻohiʻona o nā kaola a me nā pahu pahu, a ʻoi aku ka ʻoi aku o ka ʻoʻoleʻa, ka liʻiliʻi liʻiliʻi a me ka hilinaʻi ʻoi aʻe ma mua o nā kaola truss.
Eia nō naʻe, ma muli o ke kuʻi ʻana o nā papa kila, ʻoi aku ka kiʻekiʻe o ke kaumaha ponoʻī a me ke kumukūʻai ma mua o nā kaola truss. He kūpono no ka hoʻohana pinepine ʻana a i ʻole nā wahi hoʻokiʻekiʻe kaumaha a i ʻole nā wahi kukuna. Ma muli o kēia ʻano o ka beam he huahana proprietary, ʻoi aku ka liʻiliʻi o nā mea hana.
