1.Precise straight hole for better blast result control.
2.Increasing stripping speed by combining and pre-splitting holes.
3.Reducing waste by increasing slope angle.
4, Flexibility and maneuverability
RCZ440 hydraulic rock drilling rig 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.
5, Convenient maintenance and service access
As with other Rancheng drills, RCZ440 hydraulic DTH drilling machine design in mind with maintenance and service convenience at the beginning. With a spacious service room, all maintenance access points are easy to reach.

6, The more vertical the bench slope the better the production economy
Pre-splitting by RCZ440 hydraulic DTH drilling rig 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.
7.Rock falling protected FOPS and rollover proof ROPS, all view AC cab with noise and shockproof.
8.All enclosed structural rig, pneumatic spring protection doors for easier maintenance and service.
9.Round table rod ( pipe) change system, excellent for deep hole drilling.
10.3.5" / 4"hammer rotary head, torque up to 2,800 Nm.
11, Excellent return on investment
RCZ440 hydraulic DTH drilling rig 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.
12, High efficiency, energy saving, environment friendly, safety
Dual-stage air compressor for excellent energy performance ratio and high air pressure drilling. Excellent Fuel economy is better for energy saving and the environment.
High torque rotary head to conquer jamming in most rock formations.
Two-stage dust collection system to meet environmental requirements.
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.
