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.
