Product Description
Key Features

Lightweight Modular Design for Remote Access
The EP300’s ultra-portable design weighs just 630kg in total, with 6 disassemblable modules (heaviest at 180kg) that require no heavy lifting equipment for transport. Its compact 3m×3m footprint fits in tight spaces, making it ideal for mountainous, forested, or logistically challenging sites where large rigs cannot operate.

Versatile Performance for Multi-Formation Drilling
Equipped with a robust top drive system delivering 480N·m torque and 950rpm, the rig handles diverse drill rods (HTW/NTW/BTW) and hole sizes (96mm to 60mm). The 45°–90° adjustable drilling angle (customizable to 0°–90°) supports both vertical and inclined boreholes, while the 60L/min mud pump ensures efficient flushing in soft to medium-hard formations.

Reliable Power & Hydraulic Efficiency
Powered by a Kubota diesel engine, the EP300 delivers consistent power output with a 21MPa maximum pressure and 80L/min peak flow rate. The double-cylinder pull/thrust system (60kN/30kN) provides precise control during coring and tripping, while the 70m/min winch speed minimizes downtime for faster project turnaround.

Application
-
Mineral Exploration:
Ideal for small-to-medium-scale prospecting projects, including gold, copper, and base metal exploration. It delivers reliable core samples at depths up to 300 m with HTW/NTW/BTW rods, supporting resource evaluation and grade assessment.
-
Geotechnical & Engineering Site Investigations:
Widely used in infrastructure projects such as dams, bridges, roads, and building foundations. Its adjustable drilling angles (45°–90° standard, customizable to 0°–90°) allow both vertical and inclined boreholes to assess soil and rock stability.
-
Hydrogeological & Environmental Drilling:
Suitable for groundwater monitoring, aquifer testing, and environmental impact assessments. The compact design enables access to mountainous, forested, or ecologically sensitive sites where larger rigs cannot operate.
-
Remote & Rugged Terrain Projects:
Thanks to its lightweight, fully modular structure (630 kg total weight, heaviest module only 180 kg), the EP300 can be manually disassembled and transported by foot or small vehicles, making it perfect for hard-to-reach exploration zones.
