Furaha sababta ay taayirrada beddelayaashu si fudud u dejin karaan noocyada kala duwan ee taayirada waxay ku jirtaa awoodda ay bixiyaan nidaamyada hawo-mareenka ama pneumatic. Soo bandhigida faraqa u dhexeeya awooda labadan nidaam waxay kaa caawinaysaa inaad doorato bedelka taayirrada saxda ah ee xaaladaada gaarka ah, taasoo hagaajinaysa hufnaanta hawleed.

Awoodda "Herculean" ee beddelayaasha taayirrada waxay si buuxda ugu tiirsan tahay laba hab oo awoodeed oo waaweyn: Haydarooliga iyo pneumatic, kuwaas oo si weyn u kala duwan oo ku habboon xaaladaha kala duwan. Nidaamyada Haydarooliga waxay xooga saarayaan "xasilooni iyo awood," ku gudbinta xoogga cadaadiska dareeraha ah si ay u keenaan wax soo saar sare oo joogto ah, si fududna u maareynaya taayirada adag ee la iska saaro sida taayirada dhumuc iyo ordaya. Waxay ku habboon yihiin dukaamada waaweyn ee dayactirka iyo dayactirka baabuurta ganacsiga, in kasta oo ay ka muuqdaan dhismayaal adag iyo waqtiyo bilowga ah oo xoogaa gaabis ah. Nidaamyada pneumatic, dhinaca kale, waxay mudnaanta siinayaan "xawaaraha iyo dardargelinta," oo ay kaxeyso hawo ciriiri ah si degdeg ah u bilawdo iyo hawlgal habboon. Waxay ku fiican yihiin dukaamada dayactirka yar yar iyo dayactirka mootada ee ku lug leh taayirada khafiifka ah, oo bixiya dhismayaal fudud iyo dayactir yar. Farqiga udub-dhexaadku wuxuu ku jiraa hababka wax-soo-saarka awoodda iyo xaaladaha codsiga: nidaamyada hydraulic waxay diiradda saaraan "xoogga," halka nidaamyada pneumatic ay diiradda saaraan "xawaaraha." Fahamka kala duwanaanshahan wuxuu kuu oggolaanayaa inaad doorato nidaamka awoodda baahiyahaaga dayactir, hubinta kaydinta shaqada iyo waxtarka labadaba.
