YX-20 Crawler Hydraulic Core Drilling Rig

Product Overview

The YX-20 crawler hydraulic core drilling rig is a premier 2,500-meter ultra-deep diamond core exploration rig engineered for deep wireline geological sampling, large-scale mineral prospecting, and deep stratigraphic investigation. Powered by a heavy-duty Yuchai 162 kW (220 HP) 6-cylinder turbocharged diesel engine and an ultra-high-flow hydraulic circuit (28 MPa / 460 L/min), this crawler hydraulic core drilling rig delivers a massive 40-ton (400 kN) pullback lifting capacity and top-drive spindle torque up to 6,400 N·m through a heavy-duty industrial gearbox. Engineered with an extra-long 3,800 mm feed stroke, dual heavy-duty winches (2,000 m wireline core hoist + 15-ton main crane winch), an onboard BW-320 high-volume mud pump (320 L/min), and an integrated 11 kW hydraulic generator (220V/380V), this flagship 2500m diamond core drilling rig provides exploration contractors with unmatched penetration speed, supreme structural stability, and complete off-grid autonomy in remote mountainous terrain.

Product Features

High-Output Yuchai 162 kW 6-Cylinder Turbocharged Engine: Powered by an industrial 162 kW (220 HP) 6-cylinder turbocharged diesel engine delivering immense power reserves and driving high-capacity multi-circuit hydraulics (460 L/min @ 28 MPa) under extreme deep-strata coring resistance.
40-Ton Pullback & Extra-Long 3,800 mm Feed Stroke: Features a heavy-duty mast delivering 400 kN (40 Ton) of pullback force and 200 kN (20 Ton) of feed thrust across an extended 3.8-meter stroke, accommodating long drill pipe assemblies in a single continuous pass to accelerate tripping cycles.
Heavy-Duty Gearbox with 6,400 N·m Torque: Heavy-duty variable-speed gear transmission generates extreme breakout torque (1,000–6,400 N·m) at lower RPMs for setting heavy casing strings and freeing tight drill strings, while maintaining high spindle speeds up to 1,100 rpm for diamond wireline core drilling.
Dual-Winch System (2,000 m Wireline Hoist + 15-Ton Main Winch): Features a high-speed 1,000 kg wireline hoist spooling 2,000 meters of 6 mm cable for deep core barrel retrieval, alongside a massive 15,000 kg (15 Ton) main lifting winch (24 mm steel cable) for handling heavy casing strings and large downhole tool assemblies.
Onboard BW-320 High-Flow Mud Pump: Directly integrated into the primary hydraulic system, the BW-320 mud pump delivers high circulating volumes up to 320 L/min at pressures up to 10 MPa (100 bar) for borehole cleaning and diamond bit cooling down to 2,500 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 12.7-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 ground support that isolates dynamic vibration during high-speed diamond core rotation.

Applications

Ultra-Deep Mineral Core Exploration: Wireline diamond core exploration of gold, copper, lithium, polymetallic deposits, and coal beds up to 2,500 m (BTW) / 2,000 m (NTW) / 1,000 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 makes the YX-20 the flagship drilling rig in the series?

A: The YX-20 is built for extreme deep exploration down to 2,500 m BTW / 2,000 m NTW / 1,000 m HTW. It delivers industry-leading metrics: a 162 kW Yuchai engine, 460 L/min hydraulic flow, 40-ton pullback capacity, 6,400 N·m torque, an extra-long 3.8 m feed stroke, a 2,000 m wireline core hoist, a massive 15-ton auxiliary lifting winch, and an onboard BW-320 mud pump (320 L/min).

Q2: What is the benefit of the 15-ton heavy-duty main lifting winch on the YX-20?

A: In deep holes between 1,500 and 2,500 meters, heavy casing strings, drill collars, and downhole assemblies generate massive hanging weights. The 15-ton auxiliary crane winch (using 24 mm heavy steel cable) allows drill crews to hoist and seat large casing programs without requiring an external mobile crane on site.

Q3: How does the extra-long 3,800 mm feed stroke accelerate drilling operations?

A: The 3.8 m feed travel stroke accommodates full-length 3-meter drill rods and core barrels in a single continuous stroke, reducing rod-tripping cycles and chuck adjustments. This saves hours of operational downtime every shift during deep 2,500-meter drilling campaigns.
