YX-4 Crawler Hydraulic Core Drilling Rig

Product Overview

The YX-4 crawler hydraulic core drilling rig is a self-propelled, high-speed diamond core exploration rig engineered for wireline geological core sampling up to 500 meters deep (BTW). Powered by a heavy-duty Yuchai 70 kW turbocharged diesel engine and high-pressure load-sensing hydraulics (20 MPa / 160 L/min), this crawler hydraulic core drilling rig delivers a rotary top-drive speed of 1,300 rpm and an outstanding 14-ton (140 kN) pullback lifting capacity. Equipped with an integrated ground-touching mast supporting 45 ∘ – 90 ∘ 45 ∘ –90 ∘ angle drilling, a dual manual and wireless remote-control travel system, and an onboard BW-100 high-pressure mud pump, this high-performance hydraulic diamond core drilling rig provides mineral exploration teams with exceptional penetration rates and reliable core recovery in rugged mountainous terrain.

Product Features

High-Power Yuchai 70 kW Turbocharged Engine: Equipped with a genuine Yuchai industrial diesel engine delivering robust torque (350–700 N·m) and low fuel consumption, paired with an efficient high-capacity air-cooling radiator for continuous operation in extreme climates.
14-Ton High-Pullback Direct-Drive Head: Delivers 140 kN (14 Ton) of retraction lifting force and 70 kN (7 Ton) feed force through a rigid direct-drive gearbox, ensuring effortless drill string extraction from deep boreholes and collapsing strata.
$4 5^{\circ} - 9 0^{\circ}$ Integrated Ground-Touching Mast: Heavy-duty structural mast with a 1,900 mm feed stroke lowers directly to ground level, forming a rigid triangular support that isolates vibration during high-speed diamond bit rotation.
Integrated 600-Meter High-Speed Wireline Hoist: Fitted with a 600 kg capacity wireline winch accommodating 600 meters of 6 mm steel cable, operating at 100–300 rpm for rapid core barrel inner-tube retrieval.
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 proportional remote control for safe carrier loading, trailer climbing, and site maneuvering.
Onboard BW-100 Triplex Mud Pump: Factory-integrated BW-100 mud pump delivers 0–100 L/min flushing flow at pressures up to 8 MPa, ensuring continuous hole cleaning and bit cooling without secondary power packs.

Applications

Deep Mineral Core Exploration: Wireline diamond core drilling for solid mineral deposits, metal veins, and lithium/gold ore bodies up to 500 m (BTW) / 400 m (NTW) / 200 m (HTW).
Engineering Geology & Tunnel Grouting: Deep anchor boreholes, dam foundation curtain grouting, and inclined pilot holes for highway and railway tunnel alignments.
Geotechnical Site Investigation: Deep borehole sampling, stratigraphic logging, and rock quality designation (RQD) verification for major civil infrastructure projects.
Geothermal & Hydrogeological Sourcing: Exploration of shallow geothermal aquifers, groundwater source identification, and environmental monitoring boreholes.
