Key Features & Performance
The SD-1200 full hydraulic crawler core drilling rig is designed for solid bed diamond and carbide bit drilling. It is widely applied in engineering geology investigations, seismic exploration, water well drilling, anchor drilling, jet drilling, air-conditioner drilling, and pile hole drilling.
1

Advanced Rotation Head: Uses advanced rotation technology driven by dual hydraulic motors with mechanical speed changing. Delivers a wide speed range and high torque at low speeds to accommodate various geological conditions.

2

Deep Drilling Capability: Reaches a maximum spindle speed of 1175rpm with a torque of 432Nm, optimized specifically for deep exploration requirements.

3

High-Efficiency Feeding: The feeding and lifting systems utilize a single hydraulic cylinder driving the chain, allowing for long feeding distances suitable for extended core drilling processes.

4

Operator Convenience: The hydraulic driving head can move away from the borehole. Combined with clamp, unscrew, and rod assistant systems, it greatly simplifies operations.

5

Reduced Down-Time: High lifting speed reduces auxiliary operations, facilitating rapid hole washing and increasing overall productivity.

6

Mast Stability: The V-style orbit on the mast provides strong rigidity between the top hydraulic head and the mast, ensuring stable rotation even at high speeds.

7

Premium Winch Systems: Features a reliable American BRADEN main winch and a fast secondary wireline winch reaching empty-drum speeds up to 205m/min.

8

Lower Work Intensity: Standard clamp and unscrew mechanisms streamline rod connections and disconnections, protecting operators from excessive strain.

9

Precise Monitoring: Equipped with real-time spindle speedometers and drilling depth gauges for precise, data-driven drilling operations.

10

Balanced Down-Hole Pressure: Back-pressure balance system helps monitor and adjust drilling pressure accurately, extending the overall lifecycle of drilling bits.

11

Concentrated Control Panel: Features a reliable hydraulic control system with valves and operation handles centralized on a single panel for quick handling of drilling incidents.

12

Safe Crawler Mobility: Equipped with a crawler base and electronic handle controllers. It also supports external control connections to ensure safe relocation.

Frequently Asked Questions (FAQ)
What is the maximum drilling depth of the SD1200 core drilling rig?
