Techinical Characters

1. Pushing structure of chained wheel mode reduces bearing capacity of roller chain, increases pullback force storage and enhances safety factor, which saves 20kw engine power.

2.  Two-speed gear is used in rotary and thrust system which is in favor of hole clearance and pullback process, and to improve working efficiency and success rates.

3. Adpot heavy-duty rock drill head as hydraulic rotary head, more suitable for dry or wet drilling and improves lifetime in dry or wet drilling.

4. The carriage with rollers can reduce the friction and improves the lifetime of extension guide.

5. Double hydraulic clamps make drill rods added and removed more conveniently and effectively.
