Fully Hydraulic Core Drilling Rig Core Geological Exploration Gold Mine Drilling Rig Diesel for Sale

Product details

The HF400D fully hydraulic core drilling rig is mainly used for core sampling operations in geological exploration, mineral exploration, hydrogeology, and engineering surveys. Compared to mechanically driven drilling rigs, it offers more power, more stable operation, more complete core sampling, and greater adaptability, making it a mainstream type of exploration drilling rig.

1. Power and Transmission Advantages

Fully hydraulic drive ensures smooth power transmission, high torque, and a wide speed range.

Smooth, shock-free start-up reduces damage to drill pipes and core tubes.

2. High Core Quality (Core Advantage)

Precise control of feed pressure and rotation speed results in high core recovery rate and good core integrity.

Suitable for light pressure and slow rotation, ideal for coring in fractured and soft formations.

Combined with wireline coring, core recovery can be achieved without lifting the drill, significantly improving efficiency.

3. Simple, Labor-Saving, and Safe Operation

Centralized operation with hydraulic handles is convenient, labor-saving, and reduces labor intensity.

Features hydraulic overload protection, anti-jamming, and anti-stuck-up protection.

Lifting, chuck, feed, and mud pump are linked for seamless operation.

4. High drilling efficiency

Fast feed rate, smooth and stable drill rod advance and retreat

Stable deep hole drilling performance, easy control of borehole inclination, and good hole quality

Can be equipped with mud pumps, winches, and other auxiliary equipment for integrated operation

5. Strong adaptability

Adaptable to various geological conditions such as hard rock, fractured zones, and soft strata

Easy to climb slopes and relocate; suitable for use in mountainous areas, hilly terrain, and mining tunnels

6. Structural and maintenance features

Compact structure, moderate size, easy to relocate and install

Reliable hydraulic system sealing, low leakage, and low failure rate
