Ezweni elihlala lishintsha lezokwakha nezimayini, isidingo semishini ethembekile nesebenzayo sibaluleke kakhulu. Phakathi kwabaholi bemboni, u-Sunward ugqama njengengqalabutho ekukhiqizeni izimbambo zamatshe ezisezingeni eliphezulu. Isungulwe ngo-1999 nguSolwazi He Qinghua, iSunward ikhule isuka ezimpandeni zayo zezemfundo yaba enye yezinkampani ezihamba phambili emhlabeni zemishini yobunjiniyela. Namuhla, inkampani izishaya isifuba ngokuba khona okuqinile kuyo yomibili imikhakha yemishini yokwakha kanye nezimayini, ihlinzeka ngezixazululo ezintsha ezihlangabezana nezidingo ezahlukahlukene zamakhasimende ayo.
Ukuzibophezela kuka-Sunward ekwenzeni okuhle kubonakala ohlwini olubanzi lwemishini yokubhoboza imigodi yamadwala, eklanyelwe ukuthuthukisa ukukhiqiza nokusebenza kahle. I-SWDE138B ingenye imodeli enjalo, eyaziwa ngokusebenza kwayo okuyingqayizivele nokuqina. Lesi sibhobho se-rock ilungele izinhlelo zokusebenza ezihlukahlukene, sinikeza opharetha amandla nokunemba okudingekayo ukuze babhekane nemisebenzi enzima yokumba. Ngobuchwepheshe obuthuthukisiwe nezici ezisebenziseka kalula, i-SWDE138B iyintandokazi phakathi kochwepheshe abafuna ukwethembeka emisebenzini yabo yokumba.
Omunye umkhiqizo ovelele ovela ku-Sunward imodeli ye-SWDE152B. Njenge-SWDE138B, i-SWDE152B yakhelwe ukusebenza kahle kukho kokubili izicelo zezimayini ezingaphezulu nezingaphansi komhlaba. Idizayini ecatshangelwayo yalo mbhobho we-rock ivumela ukuthutha nokusethwa kalula, konga kokubili isikhathi nezinsiza kumasayithi omsebenzi. Ukwakhiwa kwayo okuqinile kuqinisekisa ukuphila isikhathi eside, okuyenza ibe yimpahla ebalulekile ezinkampanini ezigxile ekusebenzeni okuzinzile.
Izinhlobo ze-SWDQ120 kanye ne-SWDB165 ziqhubeka nokunweba iminikelo ye-Sunward esigabeni sokubhoboza imigodi yamadwala. I-SWDQ120 iphawuleka kakhulu ngokuvumelana nezimo ezihlukahlukene zokumba, okuyenza ikwazi ukusebenza kahle ezindaweni eziningi. Ngokufanayo, i-SWDB165 yaziwa ngokuthuthuka kwayo kwezobuchwepheshe okuthuthukisa isivinini sokumba nokunemba. Womabili amamodeli ahlanganisa ifilosofi ka-Sunward yokuqamba izinto ezintsha, eqinisekisa ukuthi opharetha bayakwazi ukufinyelela kumishini esezingeni eliphezulu kakhulu etholakala emakethe.
Kulabo abafuna ikhambi lezinga elikhulu, i-SWDRT270E rock hole driller iyindlela enhle kakhulu. Idizayinelwe imisebenzi enzima, le modeli ibonisa ukuzibophezela kuka-Sunward ukuhlangabezana nezidingo zamaphrojekthi anzima kakhulu. I-SWDRT270E yakhelwe ukuphatha imiqulu emikhulu yomsebenzi ngenkathi igcina ukunemba nokwethembeka. Lokhu kwenza kube yithuluzi elibalulekile kosonkontileka abenza imisebenzi ebalulekile yezimayini.
Ngokungeziwe kuxhaxha labo elimangalisayo lokumba ama-rock hole, i-Sunward iphinde yaziwe ngokubamba ingxenye yemakethe yokuqala yezinsimbi zokumba amatshe e-China. Le mpumelelo igcizelela ukuzinikela kwenkampani kwikhwalithi, ukusungula izinto ezintsha, kanye nokwaneliseka kwamakhasimende. Ngokukholelwa okuqinile ekuthuthukisweni okuqhubekayo, uSunward akayena nje umholi ekuthuthukisweni komkhiqizo kodwa futhi nakusevisi yangemva kokuthengisa, eqinisekisa ukuthi amakhasimende abo athola ukwesekwa akudingayo isikhathi eside ngemva kokuthenga kwawo.
Sengiphetha, uma usemakethe yokumba izimbobo ze-rock ezisezingeni eliphezulu, iSunward yigama ongalethemba. Ngesisekelo esiqinile kwezobunjiniyela nokuzibophezela ekusungulweni okusha, i-Sunward inikeza uhla lwemikhiqizo eklanyelwe ukuhlangabezana nezidingo eziyinselele zezimboni zanamuhla zokwakha nezezimayini. Zitholele ukusebenza kahle nokuthembeka kwababhola be-Sunward's rock hole, futhi uhlangabezane nezinga elisha lobuchwepheshe bokubhola.
