Rotary drilling rig ke mofuta oa mochini oa kaho o loketseng ts'ebetso ea ho etsa masoba ho boenjiniere ba motheo oa moaho. E loketse haholo-holo bakeng sa kaho ea lehlabathe, letsopa, mobu o nang le seretse le likarolo tse ling tsa mobu, 'me e' nile ea sebelisoa haholo kahong ea metheo e fapaneng e kang liqubu tse lahliloeng, marako a diaphragm, le ho matlafatsa motheo. Matla a lekantsoeng a "rotary drilling rig" ka kakaretso ke 117 ~ 450KW, torque ea motlakase ke 45 ~ 600kN · m, bophara ba lesoba bo ka fihla ho 1 ~ 4m, 'me botebo ba lesoba ke 15 ~ 150m, e ka fihlelang litlhoko tsa tse fapa-fapaneng tse khōlō kaho ea motheo.
Rotary drilling rig hangata e sebelisa hydraulic crawler telescopic chassis, self-lifting and landing foldable mast, telescopic kelly bar, e nang le automatic perpendicularity access and to adjust, hole deep display displaying, joalo-joalo. Ts'ebetso ea mochini oohle ka kakaretso e sebelisa taolo ea hydraulic pilot le sensing ea mojaro. . Ho bonolo ebile ho bonolo ho sebetsa.
Winch e ka sehloohong le winch e thusang e ka sebelisoa litlhoko tsa maemo a sa tšoaneng sebakeng sa kaho. E kopantsoe le lisebelisoa tse fapaneng tsa ho phunya, mochini oa ho phunya oa rotary o loketse bakeng sa ts'ebetso e omileng (e khuts'oane ea auger) kapa e metsi (emere ea rotary) le sebopeho sa mafika (core barrel) ts'ebetso ea ho etsa mekoti. E ka boela ea hlomelloa ka nako e telele ea auger, diaphragm lebota grab, vibrating qubu hamore, joalo-joalo ho finyella mesebetsi e fapaneng. E sebelisoa haholo kahong ea masepala, borokho ba litsela tse kholo, meaho ea liindasteri le ea sechaba, lerako la diaphragm ka tlas'a lefatše, paballo ea metsi, thibelo ea metsi le ts'ireletso ea matsoapo le kaho e meng ea motheo.
Tšebeliso ea mochine o monyenyane oa ho cheka oa rotary:
(1) Liqubu tsa tšireletso ea moepa tsa meaho e fapaneng;
(2) Karolo ea liqubu tse jarang meroalo ea mohaho oa mohaho;
(3) Liqubu tse fapaneng tse bophara bo ka tlase ho 1m bakeng sa merero ea ntlafatso ea litoropo;
(4) Phula bakeng sa merero e meng.
