He aha ka bumper kaʻa? He aha ia hana?
No nā mea nona nā kaʻa,ʻo ka bumper a me ka brash beam loa,ʻaʻole paha eʻike kekahi mau mea hoʻokele i kaʻokoʻa ma waena oʻelua. E like me ka palekana o ka hope loa o ke kaʻa,ʻo ka bumper a me ka chesh beam e pāʻani i kahi kūlana koʻikoʻi loa.
ʻO ka mea mua, anti-Collision Beam
Ua kapaʻia pahaʻo Roam anti-Collion Boal i keʻano o ka pahu kila anti-spell e hōʻemi i ka pahu o ke kaʻa rail, ma o kēia mea e pāʻani ana ia i kahi hana pale ma ke kaʻa. Ua hūnā pinepineʻiaʻo Anti-Collion Beams i loko o ka bumper a i loko o ka puka. Ma lalo o ka hopena o nā hopena nui,ʻaʻole hiki i nā mea elastic i ka ikaika,ʻaʻole hiki ke pāʻani i ka ikaika o ka ikaika, a ke pāʻani maoli i kahi hana i ka paleʻana i nā mea noho o ke kaʻa. ʻAʻole nā kaʻa āpau i loaʻa i ka beam anti-collious Boam,ʻo ia ka mea nui loa, e like me Aluminum Alumy, Steel Poka, a pēlā aku.
ʻElua, bumper
ʻO Bumper kahi mea palekana palekana e hoʻopili ai a hoʻopau i ka ikaika o waho a pale i ka mua a me ke kua o ke kino. ʻO ka maʻamau ma ke alo o ke kaʻa, i hoʻokaʻawaleʻia i mua a me ka hope o ka mea hana, e like me nā mea elate. ʻO ka laulā nui ka hoʻopiliʻana o ka palupuki, hoʻohana i ka papa hana paʻi ponoi,ʻaʻohe lihi o ke kaʻa aku i ka pike ma mua.
