A crane gantryhe ʻano crane i kākoʻo ʻia e nā kū pololei a i ʻole nā wāwae, a he kaola a girder paha e uhi ana i ka hakahaka ma waena o nā wāwae. ʻAe kēia hoʻolālā i ka crane e neʻe ma ka lōʻihi o ka gantry, e hāʻawi ana i ka maʻalahi i ke kau ʻana a me ka hāpai ʻana i nā ukana kaumaha. Hoʻohana pinepine ʻia nā crane gantry i nā wahi ʻoihana, e like me nā pā hale hoʻouna, nā kahua kūkulu, a me nā hale hana, no ka hāpai ʻana a me ka hoʻoneʻe ʻana i nā mea kaumaha a me nā lako. Loaʻa lākou i nā nui like ʻole a me nā hoʻonohonoho e kūpono i nā koi hāpai like ʻole.
ʻO ke kumu nui o kahi gantry girder ka hāʻawi ʻana i ke kākoʻo a me ke kūpaʻa no kahi crane a i ʻole nā mīkini kaumaha ʻē aʻe. Hoʻohana pinepine ʻia ia i nā wahi ʻoihana e like me nā kahua kūkulu, nā hale hana moku, a me nā hale hana e hoʻomaʻamaʻa i ka neʻe ʻana o nā ukana kaumaha. Kōkua ka gantry girder i ka hoʻolaha ʻana i ke kaumaha o nā mīkini a me nā ukana āna e lawe ai, e hōʻoiaʻiʻo ana i ka hana palekana a me ka maikaʻi.
