Nā loina hoʻolālā o ka ʻupena kiaʻi alanui

ʻO ka ʻoihana kiaʻi alanui, ʻoi aku hoʻi i ka wā e kū ai nā kaʻa i nā kūlana ulia pōpilikia a ʻalo a nalo paha i ka mana a holo wikiwiki mai ke alanui, e hiki ʻole ai i nā ulia pōpilikia, lilo ka palekana o ka ʻoihana kiaʻi alanui. ʻOiai ʻaʻole hiki i nā kiaʻi alanui ke hōʻemi i ka hiki ʻana mai o nā ulia pōpilikia, hiki iā lākou ke hoʻemi nui i ka nui o nā mea i make i nā ulia.
ʻO ke kumumanaʻo o ka hana palekana o ke ala kiaʻi: ʻoi aku ka ikaika o nā kaʻa kiʻekiʻe. Ke hiki mai kahi ulia pōpilikia, e holo wikiwiki nā kaʻa i ke ala kiaʻi no nā kumu e like me ka haʻalele ʻana a i ʻole ka nalowale o ka mana. I kēia manawa, ʻo ka hana o ka ʻupena kiaʻi alanui ka mea e pale aku ai i ka hoʻokuʻi ʻana o nā kaʻa a me nā mea i make.
ʻO ka hoʻolālā palekana o ka pūnaewele kiaʻi alanui: ʻO ka ikehu kinetic o kahi kaʻa e pili ana i kona nui a me ka wikiwiki. ʻO ke kumu hoʻohālike, ka nui a me ka wikiwiki o nā kaʻa liʻiliʻi maʻamau i kēia manawa he ikehu kinetic ma 80km a me 120km. Ua like like ka nui o kēia mau kaʻa, a ʻo ka wikiwiki kiʻekiʻe e hiki ai i ke kaʻa ke kumu nui e hoʻoholo ai i ka ikehu kinetic o ke kaʻa.

Ka hopena hoʻohana a me ka mālama ʻana i ka ʻupena kiaʻi alanui
1. ʻAʻole kūpono wale ke kūkulu ʻana akā he mau hana maikaʻi nō hoʻi.
2. ʻO ke kani ʻana i ke kaiapuni a puni, nani ka manaʻo holoʻokoʻa. Hoʻohana nui ʻia nā ʻupena kiaʻi alanui no nā pā ma nā alaloa, nā kaʻaahi, nā kahua mokulele, nā kikowaena, nā wahi lawelawe, nā wahi i hoʻopaʻa ʻia, nā pā hale mālama ākea, nā awa a me nā māla ʻē aʻe. Hiki i ia mau ʻupena kiaʻi ke hoʻonani i ke kaiapuni, lōʻihi a ikaika, a ʻaʻole maʻalahi ke mae. ʻAʻole maʻalahi ka piko. ʻO ke koho ʻana i nā kolamu kūpono he mau paipu poepoe maʻamau me ka uhi ma luna.
Nā mea hoʻokomo: Hoʻopili ʻia ka mesh a me nā kolamu me nā wili a me nā ʻāpana metala kūikawā like ʻole a i ʻole me ka nakinaki uwea. Hoʻolālā ʻia nā wili i hoʻohana ʻia e anti-theft. Ma hope o ka wehe ʻana i ka ʻōpala, wili, passivation, vulcanization a me nā ʻenehana ʻē aʻe, hoʻohana ʻia ka palaka palaka, a ʻōmaʻomaʻo ke kala. Hana ʻia ka pauka plating me ka pauka resin kū i ka wā i lawe ʻia mai me nā waiwai anti-kahiko ʻoi aku ka maikaʻi. Pono ke kala like o ka uhi, pahee ka ili, a he omaomao ke kala. ʻAe ʻia ka ʻāʻī, ka kulu ʻana, a i ʻole nā ​​puʻupuʻu keu. Pono ka ʻili o nā ʻāpana i hoʻopaʻa ʻia me nā kīnā ʻole e like me ka nalo ʻana o ka plating a me ka hao i ʻike ʻia.
