XY-44A/XY-44AT CORE DRILLING RIG
1. Multiple speed grades inforward & reverse revolving, meeting different drilling requirements.
2. Long spindle stroke, higherdrilling efficiency.
3. AUTOMOBILE GRADE Clutch andTransmission Box, stable running, lower noise and higher transmissionefficiency.
4. Frame sliding retraction, easyto connect and replace drilling tools.
5. Water brake system to the hoistwinch, stable delivery to lower drilling tools.
