DC Drive Drawworks of Drilling Rigs Maualuluga Uta
O pa'u uma e fa'aaogaina le ta'avale ma 'au e fai i u'amea fa'ameamea.
O filifili aveta'avale ma le sa'o maualuga ma le malosi maualuga e fa'aulu fa'amalosi.
O le taofi autu e faʻaaogaina le taofi faʻapipiʻi hydraulic, ma o le taofi faʻamau o le vai poʻo le ea malulu.
O le taofi fesoasoani e faʻaaogaina le taofi eletise eletise (vai poʻo le ea malulu) poʻo le pneumatic push disc brake.
