Ukwazisa i-DHG excavator yokutshixa ukhuseleko oluphindwe kabini kwi-coupler ekhawulezayo, eyinkqubela phambili kwi-hydraulic couplers ekhawulezayo. Le nkqubo yokutshixa kabini ngokuzenzekela ngokugqibeleleyo ibeka ukhuseleko kuqala, isusa imfuneko yokufakwa ngesandla kwezikhonkwane zokhuseleko. Uyilo oluhlaziyiweyo, oluxhotyiswe ngemithombo yokhuseleko kunye neekhonkco ezikhuselekileyo, ezibonelela ngokhuseleko oluphindwe kabini ukukhusela ukungasebenzi kakuhle. Ukwahluke kwi-couplers eqhelekileyo ye-hydraulic ekhawulezayo, i-hook yangaphambili ye-DHG i-couplers ekhawulezayo ixhotyiswe ngesixhobo sokutshixa ngokuzenzekelayo ukuqinisekisa ukhuseleko oluphindwe kabini kunye noxolo lwengqondo kubaqhubi.
