Technical Features‌

Multi-Speed Transmission System‌

Offers 8–12 rotational speed grades (e.g., 100–1,200 RPM) to accommodate alloy, diamond, or PDC bit configurations, ensuring adaptability across hard-rock formations and soft sediments.

High low-speed torque (up to 8,500 N·m) enhances stability in deep-core sampling and reduces vibration-induced deviation.

Hydraulic Feed Mechanism‌

Dual-cylinder hydraulic feed with 600–1,200 mm stroke length enables precise control for large-diameter wireline coring (HQ/NQ systems), minimizing downtime during rod retrieval.

Integrated hydrostatic brake ensures smooth descent in boreholes exceeding 1,500 m depth.

Modular Mobility‌

Split-frame design allows disassembly into 10–12 components (total weight: 3.5–5.2 tons) for rapid deployment in mountainous or remote terrains.

Hydraulic clamping system with one-way oil supply and pressure lock maintains consistent grip force (≥25 kN) for drill rod stability.

Energy-Efficient Hydraulics‌

Single-gear oil pump reduces power consumption by 15–20% compared to dual-pump systems, maintaining hydraulic oil temperatures below 65°C during continuous operation.

Emergency hand pump ensures retrieval of drill strings during power outages.
