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 kūkulu ʻana, 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 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 huakaʻi, trolley travelling, cable drum, a me nā mea ʻē aʻe.
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 mea 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 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 ke kumukūʻai ma waena o nā mea ʻelua ma ka mākeke a ʻoi aku ka hopena. , koho mea hana, etc., no laila, he okoa na kumukuai.
