DXB130H & DXB190H Hydraulic Hammers

Doosan's DXB130H and DXB190H hydraulic breakers come standard with a blank-fire protection feature that uses cushion of oil at base of piston to reduce metal-to-metal contact in case of blank firing. An energy recovery system increases strike power and impact frequency by harnessing the piston's rebound energy and using it on the power stroke.

  • Upper/lower suspension system isolates the power unit from the housing
  • Main control valve system optimizes strike power
  • Main valve design reduces hydraulic pressure peaks
  • Cradle-mounted grease station delivers continuous grease flow
