YX-8 Crawler Hydraulic Core Drilling Rig

Product Overview

The YX-8 crawler hydraulic core drilling rig is a 1,000-meter heavy-duty diamond core exploration rig engineered for wireline deep-hole geological sampling, mineral exploration, and geotechnical investigations. Powered by a high-output Yuchai 118 kW 6-cylinder turbocharged diesel engine and an upgraded high-pressure hydraulic circuit (28 MPa / 280 L/min), this crawler hydraulic core drilling rig delivers an impressive 24-ton (240 kN) pullback lifting capacity and top-drive spindle torque up to 2,200 N·m through a multi-speed industrial gearbox. Equipped with an extended 2,400 mm feed stroke, a 900-meter wireline core winch, an onboard BW-150C mud pump, and an integrated 11 kW hydraulic generator (220V/380V), this rugged 1000m diamond core drilling rig provides exploration teams with autonomous drilling, on-site auxiliary power, and exceptional core recovery in remote mountainous terrains.

Product Features

High-Output Yuchai 118 kW 6-Cylinder Engine: Driven by a genuine Yuchai 118 kW (160 HP) 6-cylinder turbocharged diesel engine, delivering substantial power reserve and steady multi-circuit hydraulic delivery under heavy deep-hole coring resistance.
24-Ton Pullback & Extended 2,400 mm Feed Stroke: Features a heavy-duty feed mast delivering 240 kN (24 Ton) pullback force, 120 kN (12 Ton) thrust force, and an extended 2.4 m stroke, accelerating rod tripping and effortlessly handling deep casing strings.
Multi-Speed Gearbox with 2,200 N·m Torque: Heavy-duty variable-speed transmission provides high breakdown torque (up to 2,200 N·m) at low speeds for breaking stubborn joints and 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 delivers stable 220V/380V AC power for night-shift camp lighting, electric welding, and power tools without carrying separate generator sets.
900-Meter High-Capacity Wireline Core Hoist: Equipped with an 800 kg capacity wireline core winch spooling 900 meters of 6 mm steel cable, operating at 100–300 rpm for rapid core barrel inner-tube recovery from deep strata.
Onboard BW-150C Triplex Mud Pump: Factory-integrated BW-150C mud pump provides high flushing flow (0–150 L/min) at up to 8 MPa, ensuring thorough hole evacuation and diamond bit cooling in 1,000-meter boreholes.
Dual Manual & Wireless Remote Undercarriage: Heavy-duty 7-ton steel crawler chassis travels at 3.5 km/h with a $4 0^{\circ}$ climbing capacity, controlled via a proportional wireless remote console for safe loading and rough-terrain positioning.

Applications

Deep Mineral Prospecting & Resource Evaluation: Deep wireline diamond core sampling of gold, copper, lithium, polymetallic deposits, and coal beds up to 1,000 m (BTW) / 900 m (NTW) / 400 m (HTW).
Deep Geothermal Exploration & Water Wells: Drilling exploratory pilot holes for geothermal heat extraction and deep structural groundwater aquifers.
Major Infrastructure & Tunnel Engineering: Inclined ( $4 5^{\circ}$ ) and vertical exploratory boreholes, fault line evaluation, and deep foundation consolidation grouting for 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 main performance enhancements of the YX-8 compared to the YX-6 model?

A: The YX-8 increases maximum drilling depth to 1,000 meters BTW / 900 meters NTW (vs 800 m / 700 m on YX-6). It is powered by a larger 118 kW engine with an upgraded 28 MPa / 280 L/min hydraulic system. Pullback force is increased by 50% to 24 Ton (vs 16 Ton), mast stroke extends to 2,400 mm (vs 1,900 mm), torque reaches 2,200 N·m, wireline capacity expands to 900 meters, and it includes a built-in 11 kW generator.

Q2: How does the onboard 11 kW hydraulic generator benefit remote field drilling?

A: In off-grid prospecting sites, operators typically need to transport and fuel a separate auxiliary generator for site lighting and repair tools. The YX-8’s built-in 11 kW hydraulic generator runs directly off the main diesel engine, providing stable 220V and 380V electrical power for night lighting, power tools, electric pumps, and maintenance welding without transporting extra generators.

Q3: Can the YX-8 drill angled boreholes for tunnel and slope exploration?

A: Yes. The heavy-duty mast tilts and locks securely at any angle between $45^{\circ}$ 45∘ and $90^{\circ}$ 90∘. Its integrated ground-touching foot pads transfer drilling thrust directly into the bedrock, eliminating mast deflection and vibration during deep angle core drilling.
