ʻO nā kaʻa crane nā mea pono o ka ʻōnaehana crane overhead. Hana ʻia kēia mau kaʻaahi i ke kila kiʻekiʻe a lilo i kumu hoʻokumu e kākoʻo i ka ʻōnaehana crane holoʻokoʻa. Nui nā ʻokoʻa like ʻole o ka crane rails, kēlā me kēia me kāna mau waiwai a me nā pono.
ʻO ka hoʻohālikelike mua ʻana o nā kaila crane ka maʻamau DIN. ʻO kēia maʻamau ka papa inoa o ka crane rail i hoʻohana nui ʻia ma ʻEulopa, a ua ʻike ʻia no kona lōʻihi a me ka ikaika. Hoʻolālā ʻia nā kaila crane maʻamau o DIN e kū i nā ukana kaumaha a me nā mahana wela, e hoʻolilo iā lākou i mea kūpono no ka hoʻohana ʻana i nā noi ʻoihana.
ʻO ka lua o ka hoʻokaʻawale ʻana o nā kaʻa crane ka maʻamau MRS. Hoʻohana maʻamau ʻia kēia maʻamau ma ʻAmelika ʻĀkau a ʻike ʻia no kona kūpaʻa maikaʻi loa a me ke ola lōʻihi. He mea maikaʻi nā kaʻa kaʻa MRS no nā noi kiʻekiʻe kahi e neʻe mau ai nā ukana kaumaha.
ʻO ke kolu o ka hoʻokaʻawale ʻana o nā kaʻa crane ka maʻamau ASCE. Hoʻohana mau ʻia kēia hoʻokaʻawale ʻana i nā ʻōnaehana crane overhead e koi ana i nā haʻahaʻa haʻahaʻa haʻahaʻa. ʻIke ʻia nā kaʻa crane ASCE no kā lākou versatility a hiki ke hoʻohana ʻia i kahi ākea o nā noi, mai nā noi ʻoihana māmā a hiki i nā papahana hana maʻamau.
ʻO kahi hoʻohālikelike ʻē aʻe o nā kaila crane ʻo ka maʻamau JIS. Aia kēia maʻamau ma Iapana a me nā wahi ʻē aʻe o Asia, a ua ʻike ʻia no kona ikaika a paʻa. Hoʻohana maʻamau ʻia nā kaʻa kaʻa ʻo JIS i nā ʻoihana ʻoihana koʻikoʻi kahi i kau ʻia ai nā ukana koʻikoʻi ma ka ʻōnaehana kaʻa.
Ma muli o kāu koi noi noi, hiki iā ʻoe ke koho i ka crane rail i kūpono i kāu mau pono. Me nā ala crane kiʻekiʻe ma kahi, hiki iā ʻoe ke hauʻoli i kahi palekana a maikaʻiluna craneʻōnaehana hiki ke mālama i nā ukana kaumaha a holo mālie no nā makahiki he nui e hiki mai ana.
