Hfga-44 Automatic DTH Surface Drill Rig, Hydraulic Portable Drilling Machine Made in China

Production Details:

The HFGA-44 is a compact yet powerful drilling rig designed for surface quarry mining and various bench blast hole drilling applications on medium to hard rock formations. It ensures high production efficiency with its reliable performance and advanced engineering.



Enhanced drilling capabilities and improved hole quality are achieved through the integration of mature technology and continuous innovation. The HFGA-44 offers near-perfect flexibility and reliability, making it ideal for increasing productivity and achieving higher-quality drilling results.
One machine can perform multiple tasks, significantly improving stripping speed while reducing dilution rates. Its lightweight and compact design allow easy movement between job sites and benches. Due to its excellent flexibility and strong drilling power, the HFGA-44 is widely used in various drilling applications such as surface quarry and mining blast hole drilling, pre-splitting hole drilling, buffer hole and slope pressure relief hole drilling, and super deep hole drilling.

HFGA-44 Features
1. Precise straight hole drilling for better control of blasting results.
2. Increased stripping speed by combining and pre-splitting holes.
3. Reduced waste by increasing the slope angle.
4. Superior flexibility compared to traditional drill rigs.

Parameter Data:


Product Features
1. Heavy duty motor and chain feed beam, stable and reliable.
2. Box design feed beam, strong and flexible.
3. Rock falling protected FOPS and rollover proof ROPS, all view AC cab with noise and shock proof.
4. All enclosed structural rig, pneumatic spring protection doors for easier maintenance and service.
5. Round table rod ( pipe) change system, excellent for deep hole drilling.
6. 3.5" / 4" hammer rotary head, torque up to 2,800 Nm.

Excellent return on investment
HFGA-44 working pressure up to 20 bars with 3.5 m drill pipe and choices of 2 dia. sizes to choose from, good for foot hole drilling and drilling speed much faster than the competitive products.

High efficiency, energy saving, environment friendly, safety
Dual stage air compressor for excellent energy performance ratio and high air pressure drilling. Excellent Fuel economy better for energy saving and environment.
High torque rotary head to conquer jamming in most rock formations.
Two stage dust collection system to meet environment requirement.
All closed AC Cab for better view, comfortable and safe operation.
New style feed beam, excellent for direction control and stability to achieve high precision drilling.





Flexibility and maneuverability
HFGA-44 with excellent tramming ability for fast and safe moving between job sites. With adequate ground clearance and 10° oscillation on heavy duty track frame, great off road capabilities due to low gravity and balanced weight distribution. Excellent vertical and various inclined drilling even on slopes.

Convenient maintenance and service access
As with other Hanfa drills, HFGA-44 design in mind with maintenance and service convenience at the beginning. With spacious service room, all maintenance access points easy to reach. Marked and labeled at both ends of hoses & pipes and electrical wires & cables with ring labels for easier service access.

The more vertical of the bench slope the better production economy
Pre-splitting by Hanfa HFGA-44 for higher and narrower benches and sharper slope to reduce waste and less excavation, in turn to reduce dilution rate for higher production rate and better profits for the mines.
