- Hydraulic automatic feed mechanism structure improves drilling efficiency and reduces labor intensity
- Ball chunk mechanism replaces card holder, enabling non-stop rod lowering for easy, safe, and reliable operation
- Winch with cage forms duplex structure supporting star wheel, capable of withstanding strong impact
- Four groups of vertical box bearing retainer ensure sufficient rotation rigidity to handle complex geological conditions including gravel layers
- After drilling structure of crawler drill bit, replace center drilling tool promptly. Clean the hole bottom first, then blow residue clean. After bit stops rotating, slowly lift drilling tool - lifting force should be sufficient to lift the tool appropriately
- During drilling process, carefully observe casing follow-up situation, monitor hole conditions, maintain hole cleanliness when necessary, and avoid forceful drill bit extraction
