YX-12 Crawler Hydraulic Core Drilling Rig

Product Overview

The YX-12 crawler hydraulic core drilling rig is a 1,500-meter heavy-duty diamond core exploration rig engineered for wireline ultra-deep geological sampling, mineral exploration, and geotechnical investigations. Powered by a high-output Yuchai 140 kW (190 HP) 6-cylinder turbocharged diesel engine and high-capacity hydraulic circuits (28 MPa / 330 L/min), this crawler hydraulic core drilling rig delivers a massive 30-ton (300 kN) pullback lifting capacity and top-drive spindle torque up to 3,800 N·m through a multi-speed industrial gearbox. Equipped with an extended 3,500 mm long feed stroke, dual winches (1,200 m wireline core hoist + 8-ton heavy-duty auxiliary crane winch), an onboard BW-250C high-pressure mud pump (250 L/min), and an integrated 11 kW hydraulic generator (220V/380V), this premier 1500m diamond core drilling rig provides exploration contractors with exceptional drilling speed, structural stability, and complete off-grid autonomy in remote mountainous terrain.

Product Features

Heavy-Duty Yuchai 140 kW 6-Cylinder Turbocharged Engine: Equipped with a 140 kW industrial diesel engine providing high power reserve and continuous multi-circuit hydraulic delivery (330 L/min @ 28 MPa) under deep-strata coring loads.
30-Ton Pullback & Extended 3,500 mm Feed Stroke: Delivers 300 kN (30 Ton) of pullback force and 150 kN (15 Ton) of feed thrust across a 3.5-meter feed stroke, handling 3-meter drill pipes in a single continuous stroke to accelerate rod tripping and deep casing installation.
Dual-Winch System (1,200 m Wireline Hoist + 8-Ton Main Winch): Features a high-speed 1,000 kg wireline hoist with 1,200 meters of 6 mm cable for core retrieval, alongside a dedicated 8,000 kg (8 Ton) heavy-duty auxiliary lifting winch (16 mm cable) for handling heavy casing strings and drill collars.
Upgraded Onboard BW-250C High-Flow Mud Pump: Directly integrated into the primary hydraulic system, the BW-250C mud pump delivers high circulating volumes up to 250 L/min at pressures up to 10 MPa (100 bar) for hole cleaning and diamond bit cooling down to 1,500 meters.
Multi-Speed Gearbox with 3,800 N·m Torque: Heavy-duty variable-speed gear transmission generates extreme breakout torque (1,000–3,800 N·m) at low speeds and continuous high spindle speeds up to 1,300 rpm for diamond wireline core drilling.
Integrated 11 kW Brushless Hydraulic Generator: Built-in 11 kW variable-frequency brushless generator driven by the rig’s hydraulic system supplies continuous 220V/380V AC power for night-shift camp illumination, auxiliary water pumps, and electric welding.
Dual Manual & Wireless Remote Undercarriage: Heavy-duty 9.5-ton steel crawler chassis travels at 3.5 km/h with an aggressive $4 0^{\circ}$ climbing capacity, controlled via a proportional wireless remote console for safe trailer loading and rough-terrain positioning.
$4 5^{\circ} - 9 0^{\circ}$ Integrated Ground-Contact Mast: Heavy-duty structural mast lowers directly to ground level, forming a rigid triangular base that isolates dynamic vibration during high-speed diamond core drilling.

Applications

Ultra-Deep Mineral Core Exploration: Wireline diamond core sampling of solid mineral deposits, metal veins, lithium pegmatites, and deep gold ore bodies up to 1,500 m (BTW) / 1,200 m (NTW) / 600 m (HTW).
Deep Geothermal Exploration & Stratigraphic Wells: Drilling deep exploratory pilot boreholes for geothermal reservoir evaluation, deep aquifer sourcing, and seismic fault line monitoring.
Major Infrastructure & Tunnel Engineering: Inclined ( $4 5^{\circ}$ ) and vertical exploratory boreholes, deep geological fault sampling, and foundation consolidation grouting for large-scale dams, bridges, and tunnels.
Remote Off-Grid Prospecting Camps: Standalone exploration in remote wilderness where the onboard 11 kW hydraulic generator powers camp operations and maintenance welding.

FAQ

Q1: What are the primary differences between the YX-12 and YX-10 core drilling rigs?

A: The YX-12 is engineered for deeper hole exploration down to 1,500 m BTW / 1,200 m NTW (vs 1,400 m / 1,100 m on YX-10). It features a larger 140 kW engine with 330 L/min hydraulic flow, an upgraded 30-ton pullback capacity (vs 28 Ton), higher torque up to 3,800 N·m, a 1,200 m wireline hoist, a high-capacity BW-250C mud pump (250 L/min), and an integrated 8-ton heavy-duty auxiliary lifting winch.

Q2: What is the purpose of the secondary 8-ton heavy-duty main lifting winch?

A: While the 1,000 kg wireline hoist is dedicated to high-speed inner-tube core barrel retrieval, the 8-ton main winch (using heavy 16 mm steel cable) is specifically designed for lifting heavy casing strings, thick-walled drill collars, and large downhole tooling without requiring an external mobile crane on site.

Q3: How does the BW-250C mud pump support deep-hole diamond coring?

A: Drilling down to 1,500 meters requires substantial hydrostatic pressure and volumetric flow to lift cuttings through long annular spaces. The BW-250C provides high flushing flow up to 250 L/min at 10 MPa pressure, ensuring thorough borehole bottom cleaning, optimal bit cooling, and effective borehole wall stabilization with polymer or bentonite muds.
