ore Technical Characteristics‌

Multi-Speed Transmission System‌

Features 8-12 adjustable speed levels with optimized torque distribution, enabling efficient performance in both small-diameter diamond drilling (≤50 mm) and large-diameter hard alloy operations (≥89 mm).

Hydraulic controls maintain stable rotational speeds (85–1,232 RPM) under variable geological conditions, minimizing bit wear and energy consumption.

Modular Structural Design‌

Decomposes into 9 pre-assembled components (e.g., power unit, rotary head, feed mechanism) for rapid deployment in mountainous or remote areas.

Open-frame architecture simplifies maintenance access, with exposed hydraulic lines and gearboxes for visual inspections.

Safety and Control Enhancements‌

Dual reverse rotation modes (65–225 RPM) facilitate smooth stuck rod retrieval while reducing operator fatigue.

Integrated instrumentation panel monitors real-time parameters like borehole pressure and torque anomalies.

Lockable baseplate and adjustable leveling jacks ensure rig stability during high-speed drilling operations.

Flexible Configuration Options‌

Compatible with auxiliary systems such as mud pumps and pneumatic impact tools via dedicated hydraulic ports.

Supports electric motor or diesel engine power sources to accommodate grid-restricted exploration sites.

Operational Advantages‌

Maintenance Efficiency‌: Oil-immersed clutch systems and pre-lubricated bearings extend service intervals by 30–40% compared to conventional designs.

Environmental Adaptability‌: Corrosion-resistant components and IP67-rated electronics ensure reliability in humid or saline environments.

Hengwang Group's exploration core drilling rigs are certified for mineral prospecting, hydrogeological surveys, and shallow oil/gas extraction, delivering precision across vertical (90°) and inclined (80°) boreholes.
