Product Features
The RCZ440 hydraulic DTH drilling rig increases the stripping speed and reduces resource waste through pre - split hole technology, while optimizing drilling accuracy and blasting control. The rig offers greater flexibility than traditional equipment, thanks to its heavy - duty motor, chain feed beam and square box feed beam design. The drilling rig is also equipped with an anti - rockfall guard, an anti - rollover roof, a panoramic air - conditioned cab and a fully enclosed structure, which reduces noise and vibration and makes maintenance services more convenient. The round table rod ( tube ) replacement system is suitable for deep hole drilling, and the 3.5 - inch / 4 - inch hammer rotary head can provide up to 2800 Newton meters of torque. The RCZ440 drilling rig has a high return on investment and is available in two diameter sizes. It is suitable for deep hole drilling and ensures fast and efficient drilling speed. Its energy - saving, environmentally friendly and safe design, as well as its combination of flexibility and mobility, make maintenance and service access more convenient, and the steeper the vertical slope design, the better the production economics.
