Magaca Alaabta | Iskaashatooyinka Isku-Dhexinta Madaxa ee Bir-la'aanta ah |
Qalab | Waxa laga sameeyay birta aan la taaban karin, boolaladahani waxay leeyihiin iska caabin aad u wanaagsan oo u adkaysta kiimikooyinka iyo biyaha milixda ah. Waxay noqon karaan birlab khafiif ah. |
Nooca Madaxa | Madaxa Truss |
Dhererka | Waxaa laga cabbiraa madaxa hoostiisa |
Codsiga | Madaxa dhuuban ee dheeraadka ah ayaa qaybiya cadaadiska haynta si loo yareeyo khatarta burburinta birta dhuuban. Isticmaal furayaashan si aad u ilaaliso fiilada birta ah si aad u sameysid birta. Waxay kuu badbaadinayaan wakhti iyo dadaal iyagoo qodaya godadkooda oo ku dhejinaya hal hawlgal |
Heerka | Kaashashka la kulma ASME ama DIN 7504 oo leh jaangooyooyin cabbirro ah. |
1. Hufnaanta: Awoodda is-qodista ayaa meesha ka saaraysa baahida loo qabo godad-qodista ka hor, kaydinta wakhtiga iyo shaqada inta lagu jiro rakibidda.
2. Xoog iyo Joogteynta: Isku-darka birta aan fiicnayn iyo naqshadeynta madaxa truss waxay hubisaa xoogga sare iyo cimri dhererka, xitaa culeysyo culus ama jawi adag.
3. Kala duwanaansho: Kala duwanaansho: Ku habboon birta, aluminium iyo qalab kale, taas oo ka dhigaysa mid ku habboon codsiyada warshadaha iyo dhismaha ee kala duwan.
4. Racfaan Quruxda: Dhammaystirka birta ah ee birta ah waxay bixisaa muuqaal quruxsan, taas oo muhiim u ah codsiyada muuqda.
5. Waxtarka-kharashka: Iyadoo qiimaha bilowga ah laga yaabo inuu ka sarreeyo marka la barbardhigo birta caadiga ah, hoos u dhigista wakhtiga rakibidda iyo baabi'inta tillaabooyinka hore ee qodista waxay keeni kartaa kaydinta kharashka guud.
6. Talada Qodista Nafta: U sahlaysa in ay dhex gasho walxaha iyada oo aan loo baahnayn qodis ka hor. Habkani wuxuu dedejiyaa rakibaadda waxayna yaraynaysaa baahida qalab dheeraad ah.
7. Iska-caabbinta Daxalka: Birta aan-dhalatada lahayn waxay siisaa iska caabin heersare ah oo u leh miridhku iyo daxalka, taasoo ka dhigaysa boolal ku habboon xaaladaha dibadda iyo qallafsan ee deegaanka.
Madaxa dhuuban ee dheeraadka ah ayaa qaybiya cadaadiska haynta si loo yareeyo khatarta burburinta birta dhuuban. Isticmaal furayaashan si aad u ilaaliso fiilada birta ah si aad u sameysid birta. Waxay kuu badbaadinayaan wakhti iyo dadaal iyagoo qodaya godadkooda oo ku dhejinaya hal hawlgal.
Dhismaha:Ku habboon birta qaab dhismeedka, samaynta biraha, iyo codsiyada kale ee qaadista.
Baabuur:Waxa loo isticmaalaa maydadka baabuurta iyo chassis si loo xidho oo sugan oo waara.
Qalabka iyo Qalabka:Ku habboon ilaalinta qaybaha birta ee qalabka guriga iyo mashiinada warshadaha.
