Sinovo e na le mochini oa ho cheka oa rotary oa Sany SR250 o rekisoang. Selemo sa tlhahiso ke 2014. Boholo ba bophara le botebo ke 2300mm le 70m. Hona joale, lihora tsa ho sebetsa ke lihora tse 7000. Thepa e maemong a matle ebile e na le 5 * 470 * 14.5m friction kelly bar. Theko ke $187500.00. Haeba u thahasella, ka kōpo ikutloe u lokolohile ho ikopanya le rona.
Sany SR250 rotary drilling rig e ka fetola pakeng tsa mokhoa oa ho cheka oa rotary le mokhoa oa CFA (continuous flight auger) ka mor'a ho fetola lisebelisoa tse fapaneng tsa ho sebetsa (liphaephe tsa ho phunya).
Sany SR250 rotary drilling rig ke sesebelisoa sa ho cheka sa qubu se nang le mesebetsi e mengata ebile se sebetsa hantle haholo. E sebelisoa haholo kahong ea merero ea motheo ea qubu e kang merero ea ho baballa metsi, meaho e mekato e phahameng, kaho ea sephethephethe sa litoropo, literene, litsela tse kholo le marokho.
The SR250 rotary drilling rig e hlahisoang ke Sany Heavy Machinery Co., Ltd. e nka mochini oa "hydraulic expandable crawler chassis" o hlahisoang ke popane, e ka tlohang le ho oa ka boeona, ea mena palo, ea fetola perpendicularity ka bo eona, ka ho iponela botebo ba lesoba, ka ho toba. bonts'a liparamente tsa boemo bo sebetsang skrineng sa ho ama le ho beha leihlo, 'me ts'ebetso eohle ea mochini e amohela taolo ea sefofane sa hydraulic le automation ea PLC. load sensing, e leng bonolo, e qhekella ebile e sebetsa.
