CORTECH® CE Certified Full Hydraulic Top-Drive Surface Core Drilling Rigs (500m - 3000m)

Manufactured under ISO 9001/14001/45001 Systems by Jinneng Holding Equipment Manufacturing Group | A Member of Jinneng Holding Group (Fortune Global 500 Enterprise)

Product Overview

Core Advantages & Engineering Highlights

• Precision Top-Drive Hydraulic Infrastructure: Driven by high-pressure 22 MPa to 28 MPa hydraulic circuit loops paired with industry-proven Cummins and Kubota turbocharged diesel engines (24.5 kW to 242 kW). Heavy-duty air-cooled radiator arrays guarantee continuous operation without thermal degradation or torque drops in extreme ambient site temperatures.

• Elite Diamond Wireline Optimization: Universally compatible with standard B/BQ, N/NQ, H/HQ, and P/PQ size wireline drill strings. High-capacity independent wireline winches supply rapid bare-drum lifting speeds up to 120 m/min with steel rope capacities up to 2,500 meters to slash auxiliary tripping non-drilling cycle times.

• Innovative Downhole Load Management: Our deep-hole flagships reject volatile push-pull feed control. By integrating advanced lateral side-shifting top drives or chuck-type power heads for unobstructed rod handling, telescopic mast architectures (up to 13.7m), and specialized balance-principle weight control systems, operators neutralize deadweight string load vectors to protect diamond bit crowns.

• All-Terrain Mobility & High-Adaptability Chassis: Heavy-duty crawler models feature rugged steel track chassis supporting up to 30° gradeability and outward-extendable hydraulic outriggers to widen the platform footprint and dampen harmonic rotation vibrations. Remote exploration lines utilize ultra-portable split configurations to bypass road access limits.

• Fortune Global 500 & ISO Certified Manufacturing Trust: Developed in a state-of-the-art manufacturing hub fully certified under ISO 9001 (Quality), ISO 14001 (Environmental), and ISO 45001 (HSE) international management frameworks. Backed by full corporate capitalization of Jinneng Holding Group, our official global trade channel provides absolute technical transparency, OEM warranty guarantees, and long-term overseas spare parts supply chain support.

Applications by Industry

• Mineral Exploration: Tailored for deep-seated gold, copper, iron, potash, and lithium deposit delineation requiring high-accuracy HQ/NQ/BQ diamond wireline core extraction.
• Geotechnical & Infrastructure Surveys: Trusted for precise borehole sampling in large-scale dam safety stabilization, railway tunnel alignment testing, and deep structural foundation analysis.
• Remote Wilderness & Roadless Mobilization: Optimized for rapid, cost-effective setup in restricted alpine terrains, dense jungles, or high-temperature deserts utilizing high-mobility crawlers or man-portable modular split configurations (like CSD500CE) that eliminate site preparation costs.
