Applications
Tunneling & Underground
Controlled excavation in confined spaces.
Controlled excavation and removal in confined spaces
Tunnel, metro and underground infrastructure projects combine face advance, rock reinforcement and secondary breaking. In a narrow, enclosed environment, low vibration, a controlled profile and minimum downtime are critical.
HKM attachments combine drill-and-crack with mechanical excavation for safe, efficient progress underground; they work with low vibration to protect the surrounding structures.

Breaks oversized blocks at the tunnel face and in secondary breaking, and trims the floor and profile; offers an alternative to blasting in enclosed spaces.
Anchor and grouting holes
Opens auxiliary holes ahead of rock reinforcement with bolting, anchor and grouting holes.
Profiling and scaling
Precisely shapes the tunnel profile, cleans excess after excavation (scaling) and advances in medium-hard rock with low vibration.
Surface with axial milling
The vertical drum provides vibration-free, controlled excavation in tunnel-wall and surface correction.
Drill-and-crack array (soon)
Opens a hole array for drill-and-crack at the tunnel face; targets precise directional control in hard rock. This product line is under development.
Hydraulic Drifters
Powerful solutions for drilling and boring.
Frequently Asked Questions
Which attachments suit tunneling and underground work?
Drum cutters for controlled excavation in confined space, hydraulic breakers for profiling and demolition, and augers/drills for boring.
Why is low-vibration excavation important?
Underground, controlled low-vibration excavation protects the surrounding rock and support; drum cutters excel here.
Which class for narrow sections?
Compact classes matched to carrier size and section dimensions are recommended. Share your site and we will determine the best attachment.
