Key Features
- Five-speed manual integrated gearbox with hydraulic release bearing and full synchronizer for reliable operation and extended service life
- Mechanical winch with fast lifting speed for efficient handling of bottom hole accidents
- Excellent off-road performance, particularly effective in muddy terrain conditions
- Four high-strength hydraulic legs with maximum support height of 1.5m for easy loading, moving, and stabilization during operation
Drilling Process Guidelines
Measurement: Regularly measure drilling depth (every 10m or when changing drill bits) and check gearbox components for overheating or abnormal sounds.
Water Supply: When using clean water drilling, ensure proper water flow before commencing operation and maintain adequate volume to prolong pump service life.
The pneumatic drilling machine utilizes high-pressure air as its power source, making it particularly effective for water intake projects in mountainous rock strata and various industrial drilling applications.
