Lefatšeng la tlholisano la merafo, ho ba le lisebelisoa tse tšepahalang le tse sebetsang hantle ho bohlokoa ho netefatsa tlhahiso le phaello. Sunward, k'hamphani e etelletseng pele ea lisebelisoa tsa boenjiniere e thehiloeng ka 1999 ke Moprofesa He Qinghua ea nang le pono, e ipehile e le sebapali sa bohlokoa indastering ena. Ka boitlamo ba boqapi le boleng, Sunward e fana ka mefuta e mengata ea meepo e tsoetseng pele ea meepo e hlokomelang litlhoko tse fapaneng tsa merafo.
Joaloka k'hamphani, Sunward e hatetse pele haholo lekaleng la boenjiniere, ea boloka sebaka sa eona har'a "Baetsi ba Mechini ba Kaho ba 50 ba ka Holimo lefatšeng ka bophara" le "Likhoebo tse 3 tse holimo tsa lefats'e tsa ho hira lifofane." Sunward ha e sebetse hantle feela ka thepa ea ho etsa thepa ea ka holim'a lefatše le ea ka tlas'a lefatše empa e boetse e na le karolo ea pele ea 'maraka litsing tsa ho cheka mafika Chaena. Katleho ena e ka hlahisoa ke boitelo ba eona bo sa thekeseleng ba lipatlisiso le nts'etsopele, hammoho le motheo o matla oa thuto oo Moprofesa He a o kenyelletsang.
Har'a lihlahisoa tse pharalletseng tsa Sunward ke Wholesale CYTM41, mochini oa merafo o etselitsoeng ho nepahala le ho sebetsa hantle. Ka theknoloji ea morao-rao le kaho e matla, CYTM41 e etselitsoe ho sebetsana le maemo a thata ka ho fetisisa a merafo. Mochine ona o ntlafatsa tlhahiso ka bokhoni ba oona bo phahameng ba ho cheka 'me ke sesebelisoa sa bohlokoa bakeng sa lik'hamphani tsa merafo tse batlang ho ntlafatsa ts'ebetso ea tsona.
Sehlahisoa se seng se hlokomelehang lethathamong la Sunward ke Wholesale SWDM160H2. SWDM160H2 e tsebahala ka ho feto-fetoha ha maemo le ts'ebetso ea eona, e etselitsoe ho fihlela litlhoko tse phahameng tsa lekala la morao-rao la merafo. Mochine ona oa merafo o etselitsoe ho cheka ka holim'a lefatše le ka tlas'a lefatše, e leng se etsang hore e be letlotlo la bohlokoa bakeng sa merero e fapaneng ea merafo. Likarolo tsa eona tse tsoetseng pele le ts'ebetso e tšepahalang ke bopaki ba boitlamo ba Sunward ba boleng le boqapi.
Khamphani e boetse e fana ka Wholesale SWDE152S, e etselitsoeng lits'ebetso tse hlokang ho cheka ka nepo. Mochine ona oa merafo o hatisa lebelo le katleho, ho netefatsa hore mesebetsi ea merafo e ka tsoela pele ntle le tieho e sa hlokahaleng. SWDE152S e na le theknoloji ea morao-rao e ntlafatsang ts'ebetso ha e ntse e boloka polokeho le ts'epo.
Ntle le mefuta ena, Sunward e fana ka li-Cutting Drilling Rigs SWDR138 le Wholesale SWDE200B, tse eketsang linyehelo tsa tsona tsa lihlahisoa. E 'ngoe le e 'ngoe ea mechini ena e entsoe ka likhatelopele tsa morao-rao tsa boenjiniere ho netefatsa ts'ebetso e nepahetseng maemong a fapaneng a merafo. Lihlahisoa tsa Sunward ha se mechini feela; li emetse motsoako oa moralo o mocha, bokhabane ba boenjiniere, le boinehelo ba ho fihlela litlhoko tse tsoelang pele tsa indasteri ea merafo.
Boitlamo ba Sunward lekaleng la merafo bo bonahatsoa ka tšebetso ea eona e matla ea mechini ea merafo. Ka ho tsepamisitse maikutlo holim'a boleng, katleho, le tsoelo-pele ea theknoloji, Sunward e mothating oa ho etella pele tlhahisong ea lisebelisoa tsa merafo. Likhamphani tse batlang ho ntlafatsa ts'ebetso le tlhahiso ea tsona li ka itšetleha ka litharollo tse tšepahalang tsa Sunward.
Qetellong, mechini ea merafo e tsoang Sunward e kenyelletsa boleng ba boqapi le boleng boo k'hamphani e e emelang. Jwaloka moetapele wa indasteri, Sunward e tswelapele ho bea maemo lekaleng la disebediswa tsa merafo, ho netefatsa hore e dula e le sehlohlolong sa kgatelopele ya thekenoloji. Ka histori e ruileng le pono e hlakileng ea bokamoso, Sunward hase feela moetsi; ke molekane ea ntseng a tsoela pele bakeng sa likhoebo tsohle tsa merafo.
