GD-800L: Advanced Fully Hydraulic Core Exploration Rig – Technical Specifications & Advantages

The GD-800L crawler-mounted, fully hydraulic drilling rig is engineered for high-efficiency core sampling, mineral exploration, and deep-hole drilling in complex geological formations.

Below is a detailed breakdown of its mechanical design, operational capabilities, and industry-leading features.

1. Drilling Performance & Capacity

Max Depth: 800m (supports HTW, NTW, BTW core barrels)

Torque Range: 1000-3500 N·m (adjustable via 3-speed gearbox )

Drill Speed: Up to 1300 RPM (stepless speed regulation for optimized penetration)

Feed Force: 12T push / 18T lift capacity (ensures stability in hard rock)

2. Hydraulic & Power System

Hydraulic Pump: 300 L/min @ 25MPa (high-pressure fluid power for smooth operation)

Cooling System: Dual air + water cooling prevents thermal overload in prolonged use.

Engine: Yuchai 6-cylinder turbo diesel (92KW @ 2200 RPM) – low fuel consumption, high endurance.

3. Structural & Mobility Features

Mast Design: Ground-mounted integrated tower with 40°–90° drilling angle adjustment.

Crawler System

Remote-controlled + manual walking (3.5 km/h speed)

45° gradeability for sloped and uneven terrain.

Winch System: 1000KG lifting force, 800m wire rope capacity (Ø6mm).

4. Automation & Patented Innovations

Auto-Lifting Mast & Power Head Shifting (exclusive utility model patents ) reduce manual labor by 30%.

Wireless remote control enables safe, precise positioning without direct operator intervention.

5. Auxiliary Systems

Mud Pump: 160 L/min @ 4-7MPa (efficient cuttings removal for clean boreholes).

Transport Dimensions: 4500×1800×2250mm (compact for logistics flexibility).

Weight: 6000KG (robust yet manageable for mobilization).

Industry Applications

Metal Mining (Au, Cu, Fe, etc.) – Deep core sampling & blast hole drilling.

Geotechnical Engineering – Soil/rock investigation, foundation testing.

Oil & Gas Exploration – Deep-well logging & sampling.
