Sebakeng se lulang se fetoha sa kaho le merafo, tšebelisano lipakeng tsa lejoe le lisebelisoa li bapala karolo ea bohlokoa ho tsamaiseng katleho le tlhahiso. Ka lilemo tse fetang mashome a mabeli, Sunward e eme ka pele ho indasteri ena, e fana ka litharollo tse ncha tse fihlelang litlhoko tse fapaneng tsa bareki ba eona lefatšeng ka bophara. E thehiloe ka 1999 ke setsebi sa pono Moprofesa He Qinghua, Sunward e fetohile ho tloha khoebong e ncha ho ba e 'ngoe ea baetsi ba lisebelisoa tsa boenjiniere ba ka sehloohong lefatšeng.
Boitlamo ba Sunward ba ho sebetsa hantle bo totobatsoa ke rekoto ea bona e tsotehang. E 'nile ea amoheloa e le e' ngoe ea "Baetsi ba Mechini ea Kaho e Phahameng ea 50 ea Lefatše" 'me e le har'a "Likhoebo tse 3 tse Phahameng ka ho Fetisisa tse hirisang Lifofane tsa Lefatše."

Boemo bona bo ka sehloohong bo tlatselletsoa ke karolo ea eona e inehetseng, Hangang Heavy Industry (Zhejiang) Technology Co., Ltd, e shebaneng le lisebelisoa tsa morao-rao tsa merafo, ka holimo le ka tlas'a lefatše.
Lejoe la motheo la katleho ea Sunward le ka har'a mefuta e mengata ea lihlahisoa tse sebeletsang mefuta e fapaneng ea lisebelisoa ka har'a rock le lisebelisoa. Mohlala, mohlala oa SWDA200C o etselitsoe ho fana ka bokhoni bo matla ba ho cheka mafika, ho netefatsa hore mesebetsi ea kaho le ea merafo e tsamaea hantle. Molekane oa eona, SWDE120B, e fana ka likarolo tse ikhethang tse reretsoeng ho ntlafatsa ts'ebetso ea ho cheka ha o ntse o boloka polokeho ea basebetsi. Lihlahisoa tsena, hammoho le SWDE165B le SWDE138B, li emela motsoako oa boenjiniere bo tsoetseng pele le moralo o shebaneng le basebelisi, e leng se etsang hore Sunward e be khetho ea mantlha bakeng sa litsebi tsa indasteri tse batlang tharollo ea majoe le lisebelisoa tse tšepahalang.
Ntle le mehlala ena, linyehelo tsa Sunward li kenyelletsa SWDA165 le SWDF200, tse bonts'ang ho feto-fetoha ha maemo ha k'hamphani le boitlamo ba ho ntlafatsa.
