Hoʻokaʻawale ʻia nā cranes Gantry e like me ko lākou helehelena a me ke ʻano. ʻO ka hoʻohālikelike piha loa o nā cranes gantry kahi hoʻolauna i nā ʻano cranes gantry āpau. ʻOi aku ka maikaʻi o ka ʻike ʻana i ka hoʻokaʻawale ʻana o nā cranes gantry i ke kūʻai ʻana i nā cranes. Hoʻokaʻawale ʻia nā ʻano hoʻohālike like ʻole o nā cranes ʻoihana.
E like me ke ʻano o ke ʻano o ka puka puka crane, hiki ke hoʻokaʻawale ʻia i nā cranes gantry a me nā cranes gantry cantilever e like me ke ʻano a me ke ʻano o ka pā puka.
ʻO nā cranes gantryua mahele hou ia i:
1. Full gantry crane: ʻaʻohe overhang ka lāʻau nui, a neʻe ka trolley i loko o ke kiko nui.
2. Semi-gantry crane: Loaʻa i nā outriggers nā ʻokoʻa kiʻekiʻe, hiki ke hoʻoholo ʻia e like me nā koi ʻenekinia kīwila o ka pūnaewele.
Hoʻokaʻawale ʻia nā cranes gantry Cantilever i:
1. ʻO ka crane cantilever lua: ʻO ke ʻano hoʻolālā maʻamau, ʻo ke koʻikoʻi o ka hale a me ka hoʻohana pono ʻana o ka wahi o ka pūnaewele he kūpono ia.
2. Hoʻokahi cantilever gantry crane: Ua koho pinepine ʻia kēia ʻano hoʻolālā ma muli o nā kapu o ka pūnaewele.
Hoʻokaʻawale ʻia e like me ke ʻano hiʻohiʻona o ka beam nui o gantry crane:
1. Comprehensive classification of single main girder gantry cranes Single main girder gantry cranes He mea maʻalahi ka hana, he maʻalahi ke hana a hoʻouka, he liʻiliʻi nui, a ʻo ka apo nui ka hapa nui o ka hale kaʻa pahu pahu. Hoʻohālikelike ʻia me ka crane gantry girder nui, ʻoi aku ka nāwaliwali o ka ʻoʻoleʻa holoʻokoʻa. No laila, hiki ke hoʻohana ʻia kēia ʻano i ka wā e hāpai ʻia ai ka mana Q≤50t a me ka span S≤35m. Loaʻa nā wāwae puka puka gantry hoʻokahi girder ma ke ʻano L a me ke ʻano C. He mea maʻalahi ka L-type e hana a hoʻouka, maikaʻi ke kūpaʻa koʻikoʻi, a he liʻiliʻi liʻiliʻi. Eia naʻe, liʻiliʻi ka wahi no ka hāpai ʻana i nā waiwai e hele i nā wāwae. Hana ʻia nā wāwae C-like i ke ʻano inclined a curved paha e hana i kahi ākea ākea nui aʻe i hiki i nā waiwai ke hele mālie i nā wāwae.
2. Hoʻopili piha ʻana i nā cranes gantry girder nui pālua. Loaʻa i nā cranes gantry nunui ʻelua i ka hiki ke halihali, nui ka lōʻihi, ka paʻa holoʻokoʻa maikaʻi, a me nā ʻano like ʻole he nui, akā ʻoi aku ka nui o kā lākou nui ma mua o ka nui o nā cranes gantry nui me ka hiki ke hāpai like. , ʻoi aku ka nui o 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 hana pahu.
Hoʻokaʻawale ʻia e like me ke ʻano o ka beam nui o gantry crane:
1. ʻO ka lāʻau truss he ʻano hana i wili ʻia e ke kila kihi a i ʻole I-beam. Loaʻa iā ia nā mea maikaʻi o ke kumukūʻai haʻahaʻa, ke kaumaha māmā a me ka pale makani maikaʻi. Eia nō naʻe, ma muli o ka nui o nā helu kuʻi a me nā hemahema o ka truss ponoʻī, ua loaʻa nā hemahema i ka pahu kuʻi e like me ka deflection nui, haʻahaʻa stiffness, haʻahaʻa haʻahaʻa 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 ka hiki ke hāpai liʻiliʻi.
2. Hoʻopiliʻia ka pahu pahu i loko o ka pahu pahu me ka hoʻohanaʻana i nā papa kila, nona nāʻano o ka palekana kiʻekiʻe a me ka paʻakikī kiʻekiʻe. Hoʻohana maʻamau no nā cranes gantry nui-tonnage a me ultra-nui-nui. Loaʻa i nā pahu pahu nā hiʻohiʻona o ke kumukūʻai kiʻekiʻe, ke kaumaha kaumaha, a me ka pale ʻana i ka makani.
