Jaakada rack:

Jidhka bini'aadamku ku wado kabaalka iyo qalabka si kor loogu qaado miisaanka qaadista. Laga soo bilaabo miisaanka guud ee aan ka badnayn 20 tan, taageerada muddada-dheer walxaha culus, Inta badan loo isticmaalo xaaladaha hawlgalka meel aan habboonayn ama loo baahan yahay in la isticmaalo cidiyaha hoose si loo qaado munaasabadaha walxaha culus, sida biraha ka soo baxa hawlaha wadada.

Jaakada istaroogga:

By bini'aadamka iyada oo loo marayo isboortiska, maroojiska ama gacanta lowska sida qaybaha sare.
Jaakadaha furayaasha caadiga ah waxay ku tiirsan yihiin dunta is-qufulka si ay u taageeraan walxaha culus, qaab dhismeedka fudud, laakiin waxtarka gudbintu waa hooseeyaa, soo laabashada tartiib tartiib ah.
Xirmooyinka is-hoosaysiinta ee is-hoosaysiinta ma laha dun is-quful ah, laakiin waxay ku qalabaysan yihiin biriiga.
Deji biriiga, walxaha culus ayaa si dhakhso ah hoos ugu dhici kara, soo gaabin wakhtiga soo noqoshada, laakiin qaab dhismeedka jaakadku wuu ka sii adag yahay.
Isku-dubbaridka qalabka taageerada muddada-dheer, miisaanka ugu sarreeya wuxuu gaadhay 100 tan, codsi ballaadhan.
Qaybta hoose ee furka toosan, laakiin sidoo kale samee walxo culus si ay u maro masaafo yar.

Jaakadaha Haydarooliga:

Waxaa wado bamka biyo-dharka ee bini'aadamka ama korantada, iyada oo loo marayo wadista nidaamka haydarooliga, oo leh dhululubada ama piston sida qaybaha ugu sarreeya. Jaakadaha Hydraulic waxaa loo qaybin karaa mid isku dhafan iyo mid gooni ah. Bamka isku-dhafan iyo dhululubada hadhidarooliga oo mid ah; kala soocidda bamka iyo hydraulic cylinder, dhexda oo leh tuubo cadaadis sare leh oo la xidhiidha. Qaab dhismeedka jaakadaha Hydraulic waa mid is haysta, wuxuu noqon karaa mid si siman u qaadaya walxaha culus, laga bilaabo miisaanka ugu badan ee 1,000 tan, safarka mitirka 1, waxtarka gudbinta ayaa sarreeya, markaa codsigu waa ka sii ballaaran yahay; laakiin ay fududahay in la daadiyo, ma taageerto walax culus oo waqti dheer ah.
Sida taageerada muddada-dheer waxay u baahan tahay in la isticmaalo jaakad is-quful ah, jaakad iskudhaf ah iyo jaakad hawo leh si loo sii yareeyo dhererka ama loo kordhiyo masaafada jacking, waxaa la samayn karaa telescopic heerar badan. Marka lagu daro nooca aasaasiga ah ee kor ku xusan ee jaakad-biyoodka, sida waafaqsan mabda'a la mid ah waxaa loo rogi karaa jaakad jaakad ah, wiish hydraulic, mashiinka kicinta, iwm, oo loogu talagalay munaasabado dhismo oo kala duwan.
