YX-22 Crawler Hydraulic Core Drilling Rig

Product Overview

The YX-22 crawler hydraulic core drilling rig is an ultra-heavy-duty 2,800-meter diamond core exploration rig engineered for wireline deep-hole geological sampling, large-scale mineral prospecting, and deep scientific drilling campaigns. Powered by a genuine Cummins 179 kW (243 HP) 6-cylinder turbocharged diesel engine and a high-flow multi-pump hydraulic system (479 L/min), this crawler hydraulic core drilling rig delivers an extraordinary 44-ton (440 kN) pullback lifting capacity and top-drive spindle torque up to 10,000 N·m through a 4-speed industrial gearbox. Engineered with a 3,600 mm feed stroke, dual winches (2,200 m wireline core hoist + 15-ton main crane winch), an onboard BW-320 mud pump (320 L/min), and an integrated 11 kW hydraulic generator (220V/380V), this top-tier 2800m diamond core drilling rig provides exploration contractors with supreme penetration power, exceptional deep-hole stability, and complete off-grid autonomy in remote mountainous terrain.

Product Features

Genuine Cummins 179 kW 6-Cylinder Turbocharged Engine: Equipped with a heavy-duty Cummins 179 kW (243 HP) diesel engine driving a 3-pump load-sensing hydraulic circuit (Main 300 L/min + Aux 125 L/min + Pilot 54 L/min @ 28 MPa) with air-cooled thermal management for continuous heavy-load drilling.
44-Ton Massive Pullback & 3,600 mm Feed Stroke: Features a reinforced structural mast delivering 440 kN (44 Ton) of pullback force and 220 kN (22 Ton) of feed thrust across a 3.6-meter stroke, handling 3-meter drill rods and heavy casing strings in a single continuous pass.
4-Speed Gearbox with 10,000 N·m Peak Torque: 4-speed mechanical gear transmission generates extreme breakout torque (1,600–10,000 N·m) at low speeds for breaking tight joints and setting large casing, while delivering stepless spindle speeds up to 1,200 rpm for diamond wireline coring.
Dual-Winch System (2,200 m Wireline Hoist + 15-Ton Main Winch): Features a high-speed 1,000 kg wireline hoist spooling 2,200 meters of 6 mm steel cable for deep inner-tube retrieval, alongside a massive 15,000 kg (15 Ton) main lifting winch (24 mm steel cable) for handling heavy drill collars and casing programs.
Onboard BW-320 High-Flow Mud Pump: Directly integrated into the primary hydraulic circuit, the BW-320 mud pump provides high circulating volumes up to 320 L/min at pressures up to 10 MPa (100 bar) for borehole cleaning and bit cooling down to 2,800 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 13-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 flatbed 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 2,800 m (BTW) / 2,200 m (NTW) / 1,100 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-22 the ultimate ultra-deep exploration rig in the series?

A: The YX-22 is engineered for extreme depth exploration down to 2,800 m BTW / 2,200 m NTW / 1,100 m HTW. It features a genuine Cummins 179 kW engine, 479 L/min multi-pump hydraulic flow, 44-ton pullback capacity, a 4-speed gearbox delivering up to 10,000 N·m torque, a 2,200 m wireline core hoist, a 15-ton auxiliary lifting winch, and an onboard BW-320 mud pump.

Q2: What is the benefit of the 4-speed gearbox and 10,000 N·m torque?

A: At depths approaching 2,800 meters, overcoming heavy string friction and freeing stuck tools require massive rotational breakout force. The YX-22’s 4-speed transmission delivers up to 10,000 N·m low-gear torque to break tight joints and set large casing, while shifting seamlessly to higher gears (up to 1,200 RPM) for high-speed diamond core drilling.

Q3: How does the Cummins engine and tri-pump hydraulic circuit handle multi-tasking?

: The 179 kW Cummins engine drives three dedicated hydraulic pump circuits (Main 300 L/min, Aux 125 L/min, Pilot 54 L/min). This dedicated circuit design ensures that top-drive rotation, feed cylinder thrust, and mud pump circulation operate simultaneously without hydraulic pressure drops or speed interference.
