Habka wax soo saarka ee tuubada alxanka leh ee wareega ah waxay ku lug leedahay isticmaalka tignoolajiyada alxanka tuubooyinka horumarsan, soo saarista tubooyinka alxanka ee hal-ama laba-geesoodka ah. Nidaamyada alxanka waxay xaqiijinayaan adkeysiga ugu badan iyo isku halaynta dhuumaha, awood u leh inay u adkeystaan adkaantakhadka gaaska dabiiciga ah ee dhulka hoostiisagudbinta.

Xarunteena wax soo saarka, waxaan dammaanad qaadaynaa in tuubooyinkeena alxanka leh ay maraan tijaabinta hubinta tayada adag si loo hubiyo heerarkooda waxqabad ee sarreeya. Waa muhiim in tuubada alxanka ahi ay la kulanto xeerarka baadhista hydraulic, xoogga adkaysiga iyo sifooyinka qabowga laablaabashada.
