The AD4 Crawler Drill is a high-performance drilling machine designed for down-the-hole (DTH) rock drilling in mining, quarrying, tunneling and construction applications. Built on a rugged tracked platform, this crawler drill offers excellent stability and mobility on uneven terrain, enabling operators to reach and drill challenging sites with ease.
• High-efficiency drilling for faster hole completion
• Crawler mount for enhanced mobility on rough terrain
• Robust construction for continuous heavy-duty use
• Suitable for DTH drilling in hard rock, coal and quarry environments
• Reduces labour costs and increases operational productivity
• Easy maintenance and long service life
• Surface mining operations
• Quarry drilling and production blasting
• Tunnel drilling and underground works
• Construction foundations and earth retention drilling
• Hard rock drilling in civil and infrastructure projects
A crawler drill combines a powerful drilling rig with a tracked undercarriage to traverse rough and inclined terrain. The AD4 model drives a DTH hammer using hydraulic power, delivering consistent impact and penetration rates while maintaining drill alignment. The combination of crawler mobility and down-the-hole power makes it suitable for long-range and deep hole drilling tasks.
