  1. In tunnel construction, DTH drill drive efficiency with unique working principles. Impact-rotation drilling crushes rock fast—1.5x faster than traditional rigs in hard rock.
  2. Multiple drills work together, cutting cycle time by over 30%. Compact design (≤2.5m height, <1.8m width) fits narrow tunnels. 360° folding arms save 20+ mins per cycle.
  3. Remote control keeps operators 50m safe from falling rocks. Dust collectors cut concentrations to 1/3 of national standards, protecting health.

 

A highway tunnel used 6 drills, achieving 8m daily progress and shortening the schedule by 40 days.
