Khamphani ea rona e thehiloe ka 2005, Ke k'hamphani e sebetsanang le tlhahiso, tlhahiso le thekiso ea likarolo tsa mechini ea kaho. Lihlahisoa tse ka sehloohong tsa k'hamphani ke likarolo tsa ka tlas'a koloi ea ho cheka (track roller, carrier roller, sprockets, idler backet tooth, track GP, jj.). Sekala sa hajoale sa khoebo: sebaka se felletseng sa li-mu tse fetang 60, basebetsi ba fetang 200, le lisebelisoa tsa mochini tsa CNC tse fetang 200, lisebelisoa tsa ho lahla, ho betla le ho futhumatsa.
Re 'nile ra ikemisetsa ho etsa lipatlisiso le nts'etsopele le tlhahiso ea mechini ea kaho ea likarolo tse sa keneng ka koloing ka nako e telele. Hona joale, lihlahisoa tsa rona li koahela boholo ba likarolo tse ka tlas'a koloi tse boima ba lithane tse 1.5-300. Setsing sa Tlhahiso ea Likarolo tsa Boenjiniere tsa Quanzhou, ke e 'ngoe ea likhoebo tse nang le mekhahlelo e felletseng ea lihlahisoa.
Hona jwale, khamphani e hlahisa haholo-holo dikarolo tsa ka tlasa koloi tse fetang ditone tse 50. E na le theknoloji ya tlhahiso e hodileng le boleng bo tsitsitseng ba sehlahiswa, mme e fetile teko ya mmaraka ka dilemo tse ngata. "Dikarolo tse kgolo tsa ka tlasa koloi, tse entsweng ke CQC" e se e le khothatso ya basebetsi ba Heli ba ikitlaelletsang ho re fihlela. Ehlile, ha re ntse re ntshetsa pele dikarolo tsa ka tlasa koloi tse kgolo tsa ditone, dikarolo tsa rona tse nyane le tse nyane tsa ka tlasa koloi tse epollang le tsona di ntse di tswela pele ka ho tswela pele. Tlhahiso e akaretsa dikarolo tsohle, mekhahlelo yohle, le dihlahiswa tsa boleng bo hodimo ho fihlela ditlhoko tsa bareki ba fapaneng ka diepolli tse fapaneng.
