YX-6 Crawler Hydraulic Core Drilling Rig

Product Overview

The YX-6 crawler hydraulic core drilling rig is a high-power, deep-hole diamond core exploration rig engineered for wireline geological sampling up to 800 meters deep (BTW). Powered by a heavy-duty Yuchai 92 kW 6-cylinder turbocharged diesel engine and high-capacity hydraulic circuits (20 MPa / 220 L/min), this crawler hydraulic core drilling rig delivers a wide spindle speed range up to 1,300 rpm and high torque output from 450 to 1,300 N·m through a robust mechanical gearbox. Engineered with an outstanding 16-ton (160 kN) pullback lifting capacity, a 700-meter high-speed wireline core hoist, and an onboard BW-150 triplex mud pump, this high-performance deep hole diamond core drilling rig delivers fast penetration rates, excellent core recovery, and dependable performance in demanding mineral exploration and geotechnical drilling campaigns.

Product Features

Heavy-Duty Yuchai 92 kW 6-Cylinder Turbocharged Engine: Equipped with a 6-cylinder turbocharged industrial diesel engine delivering 92 kW rated power, high torque reserve (450–1,300 N·m), and stable multi-circuit hydraulic output under heavy continuous drilling loads.
16-Ton High-Pullback Gearbox Transmission: Features a multi-speed gear transmission top-drive delivering 160 kN (16 Ton) of pullback force and 80 kN (8 Ton) of feed thrust, providing reliable drill string pullback and casing retrieval in deep or difficult formations.
Integrated 700-Meter High-Speed Wireline Hoist: Fitted with a dedicated 600 kg capacity wireline core winch spooling 700 meters of 6 mm wire rope, operating at 100–300 rpm for rapid, continuous inner-tube core retrieval.
Upgraded Onboard BW-150 Triplex Mud Pump: Directly integrated into the primary hydraulic system, the BW-150 mud pump supplies high-volume fluid flushing (0–150 L/min) at up to 8 MPa, ensuring thorough hole cleaning and bit cooling in deep exploration holes.
$4 5^{\circ} - 9 0^{\circ}$ Integrated Ground-Contact Mast: Heavy-duty structural mast with a 1,900 mm feed stroke lowers directly to ground level, forming a rigid triangular ground support that minimizes vibration during high-speed diamond core rotation.
Dual Manual & Wireless Remote Undercarriage: Self-propelled steel/rubber track chassis travels at 3.5 km/h with an aggressive $4 0^{\circ}$ gradeability, featuring wireless remote control for safe carrier loading, trailer climbing, and site maneuvering.

Applications

Deep Mineral Prospecting & Exploration: Deep-hole wireline diamond core exploration of gold, copper, lithium, iron, and solid mineral deposits up to 800 m (BTW) / 700 m (NTW) / 350 m (HTW).
Deep Geotechnical & Hydrogeological Sourcing: Deep aquifer exploration, geothermal gradient testing, and structural geotechnical foundation investigation for major civil infrastructure projects.
Tunnel Alignment & Mountain Grouting: Inclined ( $4 5^{\circ}$ ) and vertical pilot boreholes, geological fault exploration, and deep curtain grouting for railway and highway tunnels.
Underground Stratigraphic Logging: Continuous core extraction and rock quality designation (RQD) sampling across hard abrasive rock formations.

FAQ

Q1: What are the primary differences between the YX-6 and YX-4 core drilling rigs?

A: The YX-6 is an upgraded deep-hole machine featuring a 92 kW 6-cylinder engine (vs 70 kW on YX-4), an expanded hydraulic flow of 220 L/min, and a gearbox transmission generating up to 1,300 N·m torque. It achieves deeper drilling depths (800 m BTW / 700 m NTW vs 500 m / 400 m on YX-4), higher pullback force (16 Ton vs 14 Ton), a larger 700 m wireline hoist, and an upgraded BW-150 mud pump (150 L/min).

Q2: How does the mechanical gearbox transmission benefit deep-hole drilling?

A: Unlike pure direct-drive motors that lose torque at lower speeds, the YX-6 multi-speed gearbox delivers high starting torque (up to 1,300 N·m) at lower RPMs for setting heavy casing and breaking tight drill strings, while still maintaining high spindle speeds (up to 1,300 RPM) for diamond bit core penetration.

Q3: Can the onboard BW-150 mud pump handle thick drilling mud and polymer additives?

A: Yes. The BW-150 is a triplex single-acting piston mud pump designed to circulate bentonite slurries, polymer fluids, and clean water. With stepless hydraulic flow regulation up to 150 L/min and maximum discharge pressures up to 8 MPa, it ensures borehole stabilization and bit cooling even in deep, fractured strata.
