DXB190H
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
