YX-15 Crawler Hydraulic Core Drilling Rig

Product Overview

The YX-15 crawler hydraulic core drilling rig is an 1,800-meter ultra-deep diamond core exploration rig engineered for wireline deep-hole geological sampling, mineral exploration, and geotechnical investigations. Powered by a heavy-duty Weichai 150 kW (204 HP) 6-cylinder turbocharged diesel engine and high-capacity hydraulic circuits (28 MPa / 350 L/min), this crawler hydraulic core drilling rig delivers an extraordinary 36-ton (360 kN) pullback lifting capacity and top-drive spindle torque up to 4,000 N·m through a multi-speed industrial gearbox. Engineered with an extended 3,500 mm feed stroke, dual winches (1,500 m wireline core hoist + 10-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 1800m diamond core drilling rig provides exploration contractors with exceptional penetration rates, structural rigidity, and complete off-grid autonomy in remote mountainous terrain.

Product Features

High-Power Weichai 150 kW 6-Cylinder Turbocharged Engine: Equipped with a genuine Weichai 150 kW (204 HP) industrial diesel engine delivering robust torque reserve and high-flow hydraulic output (350 L/min @ 28 MPa) under continuous ultra-deep coring loads.
36-Ton Pullback & Extended 3,500 mm Feed Stroke: Features a heavy-duty feed mast delivering 360 kN (36 Ton) of pullback force and 180 kN (18 Ton) of feed thrust across a 3.5-meter feed stroke, handling standard 3-meter drill rods in a single continuous stroke to accelerate rod tripping and deep casing extraction.
Dual-Winch System (1,500 m Wireline Hoist + 10-Ton Main Winch): Features a high-speed 1,000 kg wireline hoist with 1,500 meters of 6 mm steel cable for continuous core barrel retrieval, alongside a heavy-duty 10,000 kg (10 Ton) auxiliary lifting winch (18 mm steel cable) for handling heavy casing strings and large downhole tool assemblies.
Multi-Speed Gearbox with 4,000 N·m Torque: Heavy-duty variable-speed gear transmission generates extreme breakout torque (1,000–4,000 N·m) at low speeds and continuous high spindle speeds up to 1,300 rpm for diamond wireline core drilling.
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 borehole cleaning and bit cooling down to 1,800 meters.
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 10.5-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 carrier 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 ground support that isolates dynamic vibration during high-speed diamond core rotation.

Applications

Ultra-Deep Mineral Core Exploration: Deep-hole wireline diamond core exploration of gold, copper, lithium, polymetallic deposits, and coal beds up to 1,800 m (BTW) / 1,500 m (NTW) / 750 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-15 and YX-12 core drilling rigs?

A: The YX-15 increases maximum exploration depth to 1,800 m BTW / 1,500 m NTW (vs 1,500 m / 1,200 m on YX-12). It is powered by a larger Weichai 150 kW 6-cylinder engine with an expanded 350 L/min hydraulic flow. Pullback force is increased to 36 Ton (vs 30 Ton), torque reaches 4,000 N·m, wireline capacity expands to 1,500 meters, and the auxiliary crane winch is upgraded to a 10-ton capacity (vs 8 Ton).

Q2: What is the benefit of the upgraded 10-ton main lifting winch?

A: In ultra-deep boreholes exceeding 1,500 meters, casing strings and heavy drill collars become exceptionally heavy. The 10-ton main winch (utilizing heavy 18 mm steel cable) provides sufficient hoisting capacity to trip heavy casing pipes and clear stuck downhole tooling directly without calling a mobile crane to the drilling pad.
