Soo bandhigidda ilkaha isku-dhafka ah ee dheemanka DB1421 ee kacaanka ah - xalka ugu dambeeya ee saameynta sare iyo iska caabbinta xirashada sare. Iyada oo leh awoodda lagu beddelayo alaabada carbide-ka, ilkahan isku-dhafka ah waxay sii jiraan ilaa 40 jeer ka dheer ilkaha jarista carbide-ka ee dhaqameed.
Ilkahan cusub waxaa si weyn loogu isticmaalaa meelo kala duwan, oo ay ku jiraan qodista injineernimada iyo goobaha dhismaha sida bits-ka roller koonka, bits-ka qodista godka hoose, qalabka qodista injineernimada, iyo mishiinnada burburinta. Qaybo badan oo gaar ah oo shaqeynaya oo ka mid ah bits-ka PDC ayaa la isticmaalaa, sida ilkaha nuugaya shoogga, ilkaha dhexe iyo cabbiraadda ilkaha, ilkaha isku dhafanna waxay gacan ka geysanayaan inay kacaan ku sameeyaan warshadaha qodista.
Iyadoo horumarinta gaaska shale ay sii kordheyso baahida loo qabo ilkaha carbide-ka ayaa hoos u dhacaysa, baahida loo qabo ilkaha isku-dhafan ee dheemanka ah ee DB1421 ayaa kor u kacaysa. Iyada oo leh xooggooda gaarka ah iyo waxqabadkooda waara, waxay si dhakhso ah u noqonayaan doorashada koowaad ee dhammaan warshadaha u baahan saameyn sare iyo iska caabin xoqid.
Ilkaha Isku-dhafka ah ee Dheemanka DB1421, waxaad filan kartaa cimri dherer iyo isku hallayn aad u fiican marka aad qodayso oo aad qodayso. Markaa, haddii aad rabto inaad ka horreyso qalooca marka loo eego hufnaanta iyo waxqabadka, ilkahan isku-dhafka ah ayaa adiga kuu ah. Ha ku qanacsanayn wax ka yar - maanta dooro Ilkaha Isku-dhafka ah ee Dheemanka DB1421 oo la kulan farqiga!
