DC Drive Drawworks ta 'Tħaffir Rigs Kapaċità Għolja ta' Tagħbija
Il-bearings kollha jadottaw dawk tar-rombli u x-xaftijiet huma magħmula minn azzar liga premium.
Ktajjen tas-sewqan bi preċiżjoni għolja u qawwa għolja huma sfurzati lubrikati.
Il-brejk prinċipali jadotta brejk tad-diska idrawliku, u d-diska tal-brejk hija mkessħa bl-ilma jew bl-arja.
Il-brejk awżiljarju jadotta brejk tal-kurrent eddy elettromanjetiku (mkessaħ bl-ilma jew bl-arja) jew brejk tad-diska push pnewmatiku.
