It is suitable for mid-soft to mid-hard rock formations, meeting the needs of high production efficiency and precise blasting control. The maximum drilling depth reaches 28 meters, making it a strong choice for deep blasthole applications.

Specifications

Key Features

1. Precise Borehole Control for Optimal Blasting
The rig ensures straight and vertical boreholes with ±1° deviation accuracy, significantly enhancing blast pattern consistency and reducing over-excavation or under-excavation in quarry operations.
 

2. Presplitting and Combined Drilling for Enhanced Stripping Efficiency
By employing presplitting and combined hole drilling techniques, the RCZ453T accelerates stripping speed by over 20% while allowing steeper bench slopes (15°–20° steeper than traditional methods), minimizing waste and cutting excavation volume by 30%.
 

3. High Maneuverability and Terrain Adaptability
Featuring a track-mounted design with 10° oscillation capability, the rig navigates 25° slopes and 300mm ground clearance with ease, enabling 50% faster site relocation compared to conventional drills, even on rugged terrains.
 

4. Low-Center-of-Gravity Design for Stability and Flexibility
Its low-center-of-gravity structure and balanced weight distribution ensure good off-road stability, supporting vertical and inclined drilling (up to 60° angles) on uneven surfaces for versatile operation.
 

5. High-Torque Rotary Head for Challenging Rock Formations
Equipped with a 2,800 Nm high-torque rotary head (compatible with 3.5"/4" hammers) and a robust chain-driven feed beam, the rig overcomes rock jamming in medium-hard formations while maintaining drilling speeds 30% faster than competitors.
 

6. Dual-Stage Air Compressor for Energy Efficiency
The dual-stage air compressor delivers 20 bar working pressure for optimal energy efficiency, reducing fuel consumption by 15% compared to single-stage systems, with a 3.5m drill pipe option for deep-hole applications (maximum depth: 28m).
 

7. Fully Enclosed Cab for Safety and Comfort
The fully enclosed AC cab with FOPS/ROPS certification (falling object/rollover protection) features shock-absorbing mounts and noise reduction (<85 dB), providing a safe and comfortable environment for operators during long hours.
 

8. 360° Visibility for Precise Operation
The cab’s 360° visibility and intuitive controls enable precise drilling on inclined benches, minimizing operator fatigue and reducing error rates in challenging conditions.
 

9. Pneumatic-Assisted Maintenance for Efficiency
Pneumatic spring-assisted access doors and a spacious service bay allow quick, tool-free access to hydraulic and pneumatic components, while color-coded hoses and labeled wiring streamline maintenance and reduce downtime by 20%.
 

10. Dual-Stage Dust Collection for Environmental Compliance
The dual-stage dust collection system captures over 95% of PM2.5 particles, ensuring compliance with strict environmental

regulations and making the rig suitable for eco-sensitive sites.
 

11. Presplitting Technology for Improved ROI
By enabling steeper bench slopes through presplitting, the rig reduces ore dilution rates and improves recovery by 5–8%, delivering a return on investment (ROI) up to 25% faster than traditional drilling methods through lower waste and higher production efficiency.
