Performance Characteristics
Electrical & Control System
- Equipped with an advanced PLC control system with servo control for fast response and smooth operation.
- Rotary torque, thrust, and pull-back force are displayed on a large color touchscreen for intuitive monitoring.
- Powerful human-machine interface enables automatic fault diagnosis and intelligent control.
- Rotation and thrust/pull-back are controlled by multifunction pilot joysticks with ergonomic design, reducing operator fatigue.
- The control panel displays rotary torque and thrust/pull-back force in real time, with adjustable proportional control of maximum output.
- The rotation system features an automatic rod-changing function; the drill can reverse within a set range when encountering hard formations.
- Automatic rotation reverse function reduces pressure and improves drilling efficiency.
- The open operator station provides wide visibility for improved safety.
Clamp & Mechanical Features
- The clamp uses a closed three-jaw structure with high clamping force, capable of traveling the full length of the mast; front and rear clamps can separate up to 254 mm.
- Floating spindle design protects drill rod threads from damage.
- Standard automatic rod handler improves construction efficiency and ensures operator safety.
Power & Mast Structure
- Dual-power hydraulic system allows selecting single or dual system operation per project requirements, greatly reducing fuel and operating costs.
- The removable rod handler reduces single-component transport weight and shortens transport length.
- Powered by a Cummins Stage III turbocharged engine for strong power and stable performance.
- The rotary head and clamp use detachable structures for easy transport, with quick-connect couplings.
- Both rotation and pull-back circuits use closed hydraulic systems for higher system pressure, no impact shock, and improved efficiency.
- Rotation uses imported Sauer-Danfoss closed-loop pumps paired with French Poclain low-speed high-torque motors for a perfect match.
- Pull-back uses Sauer-Danfoss closed-loop pumps with Brevini reducers for reliable performance in complex formations.
- The auxiliary hydraulic system uses advanced load-sensing proportional control for high efficiency and energy savings.
