Product Description


This high-quality used rotary drilling rig represents professional-grade performance for demanding foundation projects, offering exceptional value for contractors tackling large-scale construction operations. Engineered as a large-type drilling machine, it delivers superior torque and drilling depth capabilities essential for heavy-duty pile foundation work.
Full Geological Coverage: Clay, sand, silt, pebble layers, gravel layers, strongly weathered rock, moderately weathered rock, and some weakly weathered rock.
Advantageous Geological Conditions: Hard rock, large-diameter, ultra-deep borehole complex geology (compared to 155/185 models).
High-rise Buildings: Deep foundation piles for super high-rise office buildings, hotels, and residences.
Large Bridges: Main pier pile foundations for high-speed railways, highways, and cross-sea/river bridges.
Transportation Infrastructure: Deep foundation pit retaining piles and load-bearing piles for subways and light rail.
Special Projects: Heavy foundation engineering for large port terminals, wind power foundations, hydropower stations, nuclear power plants, etc.
Core Parameters: Rated torque 265kN·m; Maximum drilling diameter 2.2m; Maximum depth 73m (friction rod) / 58m (mechanical lock rod).
Powerful Engine: 257kW engine, 230kN boost pressure, main winch lifting force 275kN, high efficiency in hard rock drilling.
High-Efficiency Winch: Main winch speed 80m/min, stepped drum design, single-layer wire rope winding, extending service life by 35%.
Superior Structure: Mast and luffing mechanism adopt heavy-duty design, no cracks after 20,000 hours.
Upgraded Drill Rod: Sixth-generation 445mm thickened drill rod, with strength and wear resistance far exceeding those of its competitors.
Convenient Maintenance: Exposed power head keyway for easy inspection and replacement; external lubrication points for convenient maintenance.
Intelligent Control: 10-inch touchscreen, intelligent system, automatic leveling, fault diagnosis, and construction data recording.
Remote Management: EasyVision APP, remote monitoring of location, fuel consumption, and working hours, one-click repair reporting.
Energy Saving and Fuel Efficiency: Power optimization distribution technology, achieving overall energy savings of 10%~15%.
Telescopic Wide Chassis: 4.5m working width, 3.4m transport width, low center of gravity, and extremely high stability.
Safety Features: 360° panoramic monitoring, overload protection, and emergency stop.

Advanced hydraulic rotary head delivers powerful torque output efficiently penetrating diverse soil formations including clay, sand, gravel, and moderately hard rock layers. Variable speed control allows operators to optimize drilling parameters for different geological conditions, maximizing penetration rates while minimizing tool wear and energy consumption.
Heavy-duty tracked crawler system provides exceptional stability and weight distribution across soft or uneven terrain where wheeled equipment cannot operate safely. Wide track gauge and low ground pressure enable reliable performance on challenging ground conditions while minimizing surface damage and preventing equipment sinking during drilling operations.


Compatible with comprehensive range of drilling attachments including soil buckets, rock augers, core barrels, and specialized tools for various foundation applications. Quick-change tool connection system enables rapid switching between attachments, maximizing equipment utilization and adapting efficiently to changing geological conditions within single project site.
Strategic component layout provides convenient access to engine, hydraulic pumps, filters, and lubrication points simplifying routine maintenance procedures. Centralized automatic greasing systems reduce manual lubrication requirements and maintenance downtime. Standardized parts compatibility and comprehensive diagnostic systems enable quick troubleshooting, minimizing equipment idle time and maximizing operational availability.
