Structural Components
Pneumatic Motor
The core power component featuring high speed and torque characteristics for stable power output across various drilling hardness requirements.
Deceleration Mechanism
Converts high motor speed to optimal drilling torque, improving stability, efficiency, and reducing bit wear.
Drill Rod Clamping Device
Securely fixes drill rods during operation with excellent clamping force and stability, enabling quick changeovers between rod specifications.
Propulsion System
Hydraulic or mechanical system providing precise control of drilling depth and speed through adjustable propulsion force.
Operating Handle
Ergonomically designed control interface for all drilling functions including start/stop, speed regulation, and directional movement.
Operation Notes
- Requires compatible air compressor for stable air source pressure and flow
- Pre-operation inspection of all connections essential to prevent air leaks
- Operators must wear proper protective equipment against flying debris
