Sinovo ine yakashandiswa Sany SR250 rotary drilling rig iri kutengeswa. Gore rekugadzira ndere 2014. Iyo yakakura dhayamita nekudzika ndeye 2300mm uye 70m. Parizvino, maawa ekushanda maawa 7000. Midziyo yacho iri muchimiro chakanaka uye ine 5 * 470 * 14.5m friction kelly bar. Mutengo i$187500.00. Kana iwe uchifarira, ndapota inzwa wakasununguka kutibata nesu.
Sany SR250 rotary drilling rig inogona kushandura pakati peinotenderera nzira yekuchera uye CFA (inoenderera mberi ndege auger) nzira mushure mekushandura midziyo yekushanda yakasiyana (mapombi ekuchera).
Sany SR250 rotary drilling rig ndeye yakawanda-inoshanda uye yakakwirira-inoshanda yekukanda-mu-nzvimbo mirwi yekuchera michina. Inoshandiswa zvakanyanya mukuvaka mapurojekiti ekutanga senge mapurojekiti ekuchengetedza mvura, zvivakwa zvepamusoro-soro, kuvakwa kwemigwagwa yemumaguta, njanji, migwagwa mikuru nemabhiriji.
Iyo SR250 rotary drilling rig inogadzirwa neSany Heavy Machinery Co., Ltd. inotora iyo hydraulic expandable crawler chassis inogadzirwa negonye, inogona kusimuka nekudonha yega, kupeta mast, kugadzirisa otomatiki perpendicularity, kuona otomatiki kudzika kwegomba, zvakananga. ratidza mamiriro ekushanda ehurumende pane yekubata chidzitiro uye chekutarisa, uye iyo yese muchina mashandiro anotora hydraulic pilot control uye PLC otomatiki ye load sensing, iri nyore, ine hunyanzvi uye inoshanda.
