Makoni engarava, anozivikanwawo semakoni epachiteshi, anoshandiswa kurodha nekudzikisa ngarava dzakakurisa kuti dzimire pamahombekombe.Makoni aya anosvika pachiteshi uye anosimudza midziyo akananga kubva mungarava achiisa mumarori kana zvitima zvakamirira kumucheto kwechiteshi.

Makoni akaiswa njanji anoshandiswa muzviteshi zvine chinongedzo chenjanji kutakura zvinhu kuenda mukati menyika.Izvo zvakagadzirirwa kutamisa midziyo kubva mungarava kuenda kuchitima uye inogona kusimudza midziyo inorema kusvika 40 tonne imwe neimwe.
