DC Drive Drawworks o Rigs Drilling Kaha Uta Nui
Ka mau katoa nga uwha ki nga roera me nga rakau he mea hanga ki te maitai koranu utu nui.
Ko nga mekameka taraiwa me te tino tika me te kaha nui ka whakahinuhinuhia.
Ko te parai matua ka tango i te rei kōpae waipēhi, ko te kōpae parai he wai, he hau makariri ranei.
Ko te parai awhina e mau ana i te parai hiko eddy o naianei (te wai, te hau ranei i whakamatao) me te parai kōpae pana pneumatic ranei.
