Kwihuta ni iki?Ni ibihe bisabwa?

Umuvuduko wihuta, uzwi kandi kwihuta, ni ibinyabiziga byashyizwe mumihanda kugirango ibinyabiziga bitambuka.Imiterere muri rusange irasa, ariko nanone ingingo-isa;ibikoresho ahanini ni reberi, ariko kandi nicyuma;muri rusange umuhondo n'umukara kugirango bikurure ibitekerezo, kuburyo umuhanda wubatswe gato kugirango ugere ku ntego yo kwihuta kw'imodoka.Umukandara wo kwihuta wa reberi bikozwe mubikoresho bya reberi, imiterere ni ahantu hahanamye, ibara akenshi ni umuhondo numukara, kandi ryashyizwe kumuhanda uhuza umuhanda hamwe n’imigozi yagutse, kikaba ari ikigo cyumutekano cyo kwihutisha ibinyabiziga.Izina ry'ubumenyi ryitwa rubber deceleration ridge, ryakozwe hakurikijwe ihame ry'imfuruka y'ipine na reberi idasanzwe hasi iyo imodoka ikora, kandi ikozwe muri reberi idasanzwe.Nubwoko bushya bwibikoresho by’umutekano byihariye byashyizwe ku bwinjiriro bw’imihanda nyabagendwa, inganda n’amabuye y'agaciro, amashuri, aho gutura, n'ibindi kugirango bigabanye umuvuduko w’ibinyabiziga n’ibinyabiziga bidafite moteri.

Ibisabwa muri rusange kugirango reberi yihuta (ridges):

1. Igikoresho cyo kwihuta cya reberi kigomba kuba cyuzuye, kandi hejuru yinyuma hagomba kugira imirongo kugirango yongere ifatanye.
2. Buri gice cyihuta kigomba kuba gifite retro-yerekana ibintu byoroshye kumenyekana nijoro, ireba icyerekezo cyikinyabiziga.
3. Ntabwo hagomba kubaho imyenge hejuru, ntihakagombye kubaho ibishushanyo bigaragara, kubura ibikoresho, ibara rigomba kuba rimwe, kandi ntirigomba kubaho flash.
4. Izina ryurwego rukora rugomba gukanda hejuru yumusozi wihuta.
5. Niba ihujwe nubutaka na bolts, umwobo wa bolt ugomba kuba umwobo.
6. Buri gice cyimisozi yihuta kigomba guhuzwa muburyo bwizewe.

Igice cyambukiranya igice cyihuta cyimyanya yubugari nuburebure bugomba kuba hafi ya trapezoidal cyangwa arc-shusho.Ubugari bugomba kuba mu ntera ya (300mm ± 5mm) ~ (400mm ± 5mm), naho uburebure bugomba kuba mu ntera ya (25mm ± 2mm) - (70mm ± 2mm).Umubare wubugari nubunini ntugomba kurenza 0.7.

Icyuma cyiza cya reberi-plastike kigomba kwemeza ko ikinyabiziga kitazabura igihe ikinyabiziga kirenganye, kandi ibyingenzi byingenzi byumutekano ntibizavunika nibindi bihe bibi, kandi bigomba kugira umutekano muke kandi bifite umutekano.
