Ukwazisa ukudilizwa kwe-DHG, ukudilizwa kwe-hydraulic okutshintsha umdlalo kunye nokuhlelwa kwegrapple eyenzelwe ukuguqula indlela yokuphatha izinto ezinzima kunye nokuhlelwa kwemisebenzi eyenziwayo. Olu gqatso lusebenza ngokuphezulu ludibanisa amandla angenakulinganiswa kunye nobuchule obukhethekileyo, busenza isixhobo esisebenza ngeendlela ezininzi sokudiliza izakhiwo, ukuhambisa izinto ezininzi, kunye nokuhlenga izinto ezithambileyo ezinokuphinda zisetyenziswe ngokulula. Eyakhiwe ngamacwecwe angagugiyo kunye nentsimbi ephezulu, le extractor yakhelwe ukumelana neyona misebenzi inzima ngelixa ikhulisa umjikelo wokusebenza kwamafutha emva komjikelo.
