Application&Features
GQ-20 Building Construction Tools And Equipment is developed based on GQ-15 rig,in order to meet the needing of construction of large dia .The structure of the rig is stable and reliable.
- Large torque,light weight and small size compare to the same kind drilling machine.It is easy to move.
- The mast is like a dragon door,the top-head can move down or up on it .Large strength,drill high accurate hole.
- Inner hole of top-head is large(182 × 182mm),can drill with forward circulation or reverse circulation drilliin method.
- The rig uses DF6S900 gear box of DONG-FENG truck,it has 6 forward gears,1 reverse speed,it is suitable for drlling various earth formation.It is good to handle accidents in hole,and easy to maintain due to using general spare parts.
- Top-head is equipped with man power chuck ,drilling with Square Kelly,large depth per drilling high efficiency .
- The Oil feed cylinders make the top-hand move up and down ,pressure and depression drilling easily,and have large pull ad push force.
- The retraction distance is 1550mm,have larger distance away from hole,to make the drilling tools up and down easily.
- Have waking device ,move and find hole position easily.
- Reasonable arrangement,operation easy, nimble and reliable.
- Can be equipped with special tower, drilling more conveniently.
