Key Features 1. Power Source: Operates on compressed air, ensuring explosion-proof safety, especially suitable for gas-prone environments. 2. Lightweight & Flexible: Compact and lightweight, making it easy to maneuver in confined spaces. 3. High Efficiency: High rotational speed and torque enable fast drilling operations. 4. Strong Adaptability: Capable of working in various rock formations, including medium-hard strata. Main Components - Pneumatic motor - Gear reduction mechanism - Drill rod connection device - Operating handle - Support leg (available in some models) - Noise reduction device Applications 1. Rock bolting in coal mine roadways 2. Support operations in tunnel engineering 3. Subway construction and reinforcement 4. Other underground anchoring and support projects Usage Precautions 1. Ensure air pressure meets requirements before operation. 2. Regularly lubricate and maintain moving parts. 3. Maintain straight feed motion of the drill rod during operation. 4. Drain accumulated water in pipelines after use. 5. Periodically inspect seals to prevent air leaks. Due to its safety and efficiency, the pneumatic roof bolter has become an essential piece of equipment in underground support operations.
