Product Description
Key Features
Lightweight Modular Design for Remote Access
The EP550’s ultra-portable design weighs only 1200kg total, with 10 disassemblable modules (heaviest at 180kg) that require no heavy lifting equipment for transport. Its compact 4m×4m footprint fits in tight spaces, making it ideal for mountainous, forested, or logistically challenging sites where larger rigs cannot operate.
Versatile Performance for Multi-Formation Drilling
Equipped with a robust top drive system delivering 620N·m torque and 1167rpm, 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 100L/min mud pump ensures efficient flushing in soft to medium-hard formations.
Reliable Power & Hydraulic Efficiency
Powered by a dual Kubota diesel engine setup delivering 66kW, the EP550 provides consistent power output with a 21MPa maximum pressure and 160L/min flow rate. The double-cylinder pull/thrust system (60kN/30kN) offers precise control during coring and tripping, while the 150m/min winch speed minimizes downtime for faster project turnaround.

Application
-
Mineral Exploration
Designed for mid-depth mineral prospecting (up to 700 m with BTW rods), it delivers high-quality core samples for gold, copper, base metal, and rare earth resource evaluation. Its compatibility with HTW/NTW/BTW rods supports diverse exploration programs, from grassroots reconnaissance to advanced resource definition.
-
Geotechnical & Engineering Investigations
Widely used in large-scale infrastructure projects such as dams, tunnels, bridges, and high-rise foundations. The rig’s adjustable drilling angles (45°–90° standard, customizable to 0°–90°) enable both vertical and inclined boreholes to assess subsurface stability, rock quality, and foundation conditions.
-
Hydrogeological & Environmental Drilling
Ideal for groundwater resource assessment, aquifer testing, and environmental monitoring wells. Its compact, modular design allows deployment in remote or sensitive ecological sites where heavy equipment access is limited.
-
Remote & Rugged Terrain Operations
With a total weight of only 1200 kg and a modular setup (heaviest module just 180 kg), the EP550 can be disassembled and transported manually or by light vehicles. This makes it perfect for mountainous, forested, or logistically challenging exploration zones.
