Ibhakede lokubamba lifana nohlobo oluthile lwesandla se-excavator.Kukhona isithupha esiqinile esifakwe emzimbeni webhakede, futhi isilinda se-hydraulic yesithupha sibekwe ngemuva kwebhakede, esikusiza ukuxazulula inkinga yokulungisa ukushisela kwesilinda.Khonamanjalo, isilinda esisebenza nge-hydraulic sivikelwe kahle yi-bracket yokuxhuma ibhakede, inkinga yokushayisana kwe-hydraulic cylinder esetshenziswayo ngeke ize izokuthola.
