WITH BUILT-IN AIR COMPRESSOR+ROD MANIPULATOR/CAROUSEL SYSTEM+CABIN
Dragon GP830-2 is an all-in-one hydraulic DTH drilling rig, which brings you more automation, higher working efficiency,
better reliability and simpler operation. The FOPS-approved cabin and automatic pipe handling system are equipped.
Heavy-duty undercarriage with wide tracks ensures its travelling safety while move quickly.
Hydraulic dust collecting system meet the latest environmental protection regulations and it is reliable solution to meet the modern green mining.
Features of Dragon GP830-2 drill rig
♦ Fully automatic drilling, single operator is needed. ♦ Imported REXROTH and EATON hydraulic control components ensure the powerful torque output, meet large hole drilling needs. ♦ The Diesel engine offers strong power, impacting, feeding and rotation speed can be adjusted according to different rock conditions, suitable for various terrains. ♦ Imported Atlas two-stage air compressor can switch between two compression stages. Increase penetration rate and hole quality. ♦ Telescopic heavy-duty drill arm provide bigger fan shape drilling coverage, improve the effective drilling time.
Power train
The water-cooled EFl turbo engine offers more power, consumes less fueland complies with the National Ill emission standard.
The III stage air filtersystem ensures intake of clean air and greatly reduces the engine failure rate.
Air compressor
The high-output Atlas Copco air compressor features two stages of compression,delivering pressure. Powerful and reliable,
it suits rock formations of various hardness and offers high penetrate rate with ease.
Control system
The sealed air-conditioned cabin is made with FOPS which meets EU and US safety protection standards.
The rig's operating parameters, instructions and warnings all can be clearly displayed on the dashboard, easy forthe operator to monitor.
Rotation unit system
The rotation unit is equipped with a floating connector which can reduce vibration as well as protect pipe threads when loading/unloading drill pipes.
It is easy to be adjusted and has a long service life.
Automatic pipe handling system All the functions, such as pipe storage, pipe loading and unloading, movement of the mechanical clamps, can be controlled very easily with one single joystick.
Loading and unloading of the drill pipes are easily achieved by upper and lower clamping, greatly raising the working efficiency. Installing one-button automatic rod exchange system, faster and safer.
Undercarriage
The heavy-duty undercarriage features robust structural strength, wide tracks and excellent gradeability, which all ensure better stability while drilling.
Maintenance Maintenance and repair are very convenient as maintenance and check points are easily accessible, engine compartment is well organized,
and allservice doors can be easily opened and closed.

Efficiency The boom structure has three degrees of freedom for multi-directional positioning to ensure a wider range of drilling angles.
Rigidity The heavy-duty undercarriage features robust structural strength, wide tracks and excellent grade ability, which all ensure betterstability while drilling The feed system is driven by planetary gearbox and chain. The durable high strength chain can be easily adjusted. The bearing roller type sliding plates
have a long service life and are easy for maintenance.
Convenience Service doors can be fully opened to provide large space and easyaccess to maintenance. The rig's operating parameters, instructions and warnings all canbe clearly displayed on the dashboard, easy for the operator tomonitor.
Safety The sealed air-conditioned cabin is made with FOPS which meetsEU and US safety protection standards. Large windows provide theoperator with great visibility to
precisely control the rig. The groundclearance is over 400mm giving the rig extreme maneuverability onvarious tough terrain.
