ʻO ka ʻōlelo maʻamau, ʻaʻole hoʻohana ʻia nā cranes bridge ma waho i hoʻohālikelike ʻia me nā cranes gantry. No ka mea, ʻaʻohe hoʻolālā outrigger i kāna hoʻolālā hoʻolālā, hilinaʻi nui kāna kākoʻo i nā brackets ma ka paia o ka hale hana a me nā kaʻa i kau ʻia ma nā kaola lawe ukana. ʻO ke ʻano hana o ka crane alahaka hiki ke lilo i ka hana ʻole a me ka hana ʻāina. ʻO ka hana kaʻa kaʻa. ʻO ka maʻamau, koho ʻia ka hana ʻāina a hoʻohana ʻia ka mana mamao. He maʻalahi a palekana ka hana. ʻAʻole hiki ke hoʻokomo wale ʻia ka gantry crane i loko o nā hale hana o loko akā hiki ke hoʻohana maʻalahi i nā wahi o waho.
2. Ka ʻokoʻa ma waena o ke alahaka crane a me gantry crane
I kēia manawa, nui nā ʻano cranes bridge a me gantry cranes ma ka mākeke. Koho nā mea kūʻai aku i nā cranes bridge a i ʻole gantry cranes e like me ko lākou pono ponoʻī, ʻo ka mea nui ma ke ʻano o ka hoʻolālā lako, ke ʻano hana, ke kumu kūʻai, etc.
1. Hoʻolālā a me ke ʻano hana
Hoʻokumu ʻia ka puʻu uwapo me ke kaola nui, ka moto, ka winch, ka holo kaʻa, ka huakaʻi trolley, etc. Hiki i kekahi o lākou ke hoʻohana i nā hoists uila, a hiki i kekahi ke hoʻohana i nā winch. ʻO ka nui e pili ana i ka tonage maoli. Loaʻa i nā cranes bridge nā ʻauʻau pālua a me ka ʻauʻau hoʻokahi. Hoʻohana maʻa mau ʻia nā pahu kuʻi pālua.
Hoʻokumu ʻia ka puʻu gantry me nā kukui nui, nā outriggers, winch, kaʻa kaʻa hele, trolley travelling, cable drum, etc. ʻAʻole like me nā bridge cranes, gantry cranes he outriggers a hiki ke hoʻohana ʻia i loko a me waho.
2. Ke ano hana
ʻO ke ʻano hana o ka crane bridge i kaupalena ʻia i nā hana i loko. Hiki i ka makau ke hoʻohana i nā hoists uila pālua, i kūpono no ka hāpai ʻana i nā mea kanu hoʻoponopono, nā hale kaʻa kaʻa, ka metallurgy a me nā mea kanu ʻoihana maʻamau.
Hana ʻia nā ʻano hana like ʻole, ka mea maʻamau me nā tonnage liʻiliʻi i loko o ka hale, nā cranes kapili moku a me nā pahu gantry pahu ma waho, ʻo ia nā mea hāpai nui-tonnage, a hoʻohana ʻia nā pahu gantry no ka hāpai ʻana i ke awa. Hoʻohana kēia gantry crane i kahi hoʻolālā cantilever pālua.
3. Nā pono hana
Hoʻohana maʻamau nā cranes bridge me nā pae hana kiʻekiʻe i nā cranes metallurgical, ʻoi aku ka kiʻekiʻe o ka hana, hana maikaʻi, haʻahaʻa haʻahaʻa ka hoʻohana ʻana i ka ikehu, a hoʻokō i nā kūlana kaiapuni.
ʻO ka pae hana o nā cranes gantry maʻamau ʻo A3, ʻo ia no nā cranes gantry maʻamau. No nā cranes gantry nui, hiki ke hoʻokiʻekiʻe ʻia ka pae hana i A5 a i ʻole A6 inā loaʻa nā koi kūikawā. ʻOi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka ikehu a kū i nā kūlana palekana kaiapuni.
4. Kumu kuai lako
He maʻalahi a kūpono ka crane, me nā koina hana haʻahaʻa. Ke hoʻohālikelike ʻia me ka gantry crane, ʻoi aku ka haʻahaʻa o ke kumukūʻai. Eia nō naʻe, pono e kūʻai ʻia nā mea ʻelua e like me ke koi, a ʻaʻole like nā ʻano ʻelua. Eia naʻe, ʻoi aku ka nui o ka ʻokoʻa ma waena o nā mea ʻelua ma ka mākeke a ʻoi aku ka hopena. , koho mea hana, etc., no laila, he okoa na kumukuai.
