Ubushobozi bwo gukoresha ROP buri hejuru ugereranyije n'uduce two gucukura uduce tw'imashini zikoresha ibyuma bya roller cone
Ugereranyije n'uduce twa roller cone, uduce twa hybrid drill dushobora kongera ROP, bigasaba uburemere buke kuri bit no kugabanya bit bounce.
Imiterere myiza yo gucukura ugereranije na PDC
Ibiranga Amahitamo
Ugereranyije na PDC, ibice bivanze biraramba cyane iyo bicukura mu buryo buvanze. Bigabanya gucika kw'imitsi kandi byoroshya gucunga torque mu gihe birushaho kuba byiza, bigatuma habaho ihindagurika ryihuse mu buryo butandukanye. Gutuza no kugenzura icyerekezo bifasha kugenzura neza imiterere ihagaze ndetse no kwiyongera kw'ibyiciro mu migozi.
