A: These rigs are designed for drilling blast holes, ventilation shafts, and anchoring in coal mine tunnels. Their full hydraulic system ensures precise control, while the crawler undercarriage provides stability and mobility in confined underground spaces.
A: Hydraulic crawler drilling rigs offer high torque and variable speed control for diverse geological conditions. The crawler mobility reduces setup time between drilling positions, and their modular design enables quick maintenance in field operations.
A: Regular inspection of hydraulic fluid cleanliness and hose integrity is critical. Crawler track tension must be monitored to prevent slippage, and boom/joint lubrication should follow manufacturer intervals to ensure smooth articulation.
A: They incorporate methane detectors, emergency stop systems, and fire-resistant hydraulic fluids. ROPS/FOPS-certified cabins protect operators, while automatic leveling compensates for uneven tunnel floors during drilling operations.
A: Yes, advanced models feature high-pressure hydraulic systems delivering 25-30kN impact force. Optional rotary-percussion drilling modes and carbide-tipped bits enable penetration through hard rock strata while maintaining crawler stability during aggressive drilling.
