Hoʻokaʻawale ʻia nā kaola longitudinal o Bailey Bridge i ʻelua mau ʻano: nā kaola longitudinal me ka buckle a me ka longitudinal beam me ka ʻole o ke kī.
(1) Hoʻopili ʻia nā pihi ma nā kaola longitudinal buckle, i hoʻonoho ʻia ma nā ʻaoʻao ʻelua o ka papa alahaka. Hoʻokomo ʻia ka ʻūhā o ke alahaka ma waena o nā pihi. Hāʻawi ʻia nā pihi ʻehā me nā puka no nā mea lihi a me nā kī e hele ai i loko o nā lua. Hoʻopili ʻia ka ʻūhā uwapo me ke kaola longitudinal buckle.
(2) Hoʻonohonoho ʻia nā kaola lōʻihi me ka ʻole o ka pahu ma waena o ka ʻaoʻao o ke alahaka me ka nānā ʻole i nā ʻaoʻao mua a i hope. I kēia mau lā, ma muli o ka nui o ke kaʻa, ʻaʻole hoʻohana mau ʻia nā kaola longitudinal a me nā papa lāʻau. Hoʻohana ʻia nā deck alahaka kila Orthotropic i nā hihia he nui.
ʻO ke alahaka kila Bailey, ka pahu pahu kila a me ke kāʻei pā i hana ʻia e Zhenjiang Great Wall Heavy Industry e lawe ʻia aku i nā ʻāina he nui a hoʻokipa maikaʻi ʻia e nā mea hoʻohana. I kēia manawa ma nā ʻāina ʻekolu o ka honua, ke koi nui nei nā stringers.
