3. Core Advantages
Full Hydraulic Control: Stable performance, high efficiency & labor saving
360° Rotatable Spindle: Suitable for vertical, inclined & horizontal drilling
Trailer Portable Structure: Fast relocation, suitable for mountain & field operation
Wide Stratum Adaptability: Matches multiple bits for rock, soil & complex layers
Compact & Durable: Small size, light weight, low maintenance cost
Complete Series Technology: Covers all mainstream foundation & drilling processes
4. Application Scope
- Rocky mining core sampling & mineral exploration
- Geotechnical investigation & geological core drilling
- Water well & geothermal well drilling
- Blasting holes & grouting holes for railway, bridge, water conservancy & dam foundation
- High-rise building, highway & tunnel foundation construction drilling
- Shallow oil & gas, mine ventilation & drainage tunnel drilling
5. Common Fault Solution: Drill Pipe Sticking Handling
- Cause: Drill pipe/tools cannot lift, lower or rotate, leading to shutdown
- Simple Treatment: Blow out rock powder first; use seamless pipe with butter/asphalt to fish broken drill wings
- Severe Sticking: Apply external torque & auxiliary tools to rotate, feed air while pulling up until recovery
- Restart: Apply low pressure first, gradually increase to standard working pressure
