Ifektri yethu ingakhiqiza isixhumanisi esibanzi sethrekhi lapho iphimbo elisukela ku-90mm ukuya ku-226mm, alungele zonke izinhlobo zemishini yokukhasa ye-excavator, i-bulldozer, imishini yezolimo kanye nemishini ekhethekile.
Amaketango ethrekhi omile, amaketango ethrekhi e-excavator avalwe futhi agcotshwe ngamafutha, amaketango agcotshiwe ezinhlelo zokusebenza zokusebenza okuphezulu.
Isixhumanisi sethrekhi senziwe ukwelashwa kokuqina kwe-medium-frequency, okuqinisekisa amandla ayo aphezulu kanye nokumelana nokuhuzuka.
Iphinikhodi yenziwa ukuthambisa kanye nokwelashwa kokucisha imvamisa okuphakathi nendawo, okuqinisekisa ubulukhuni obanele bokuqina nokumelana nemihuzuko kwama-sunaces angaphandle.
Ihlathi lenziwa i-carbonization kanye nokwelashwa kokucisha okuphakathi nendawo, okuqinisekisa ubulukhuni obuzwakalayo be-core kanye ne-abrasion ukumelana kwezindawo zangaphakathi nangaphandle.
