2019 XCMG XR220D Rotary Drilling Rig

2019 XCMG XR220D Rotary Drilling Rig

• Powered by  QSL9 third-generation diesel engine, delivering robust power output and ample torque reserve—ideal for residential construction, municipal infrastructure projects, and pile foundation works for small- to medium-span bridges.
• Rated maximum rotary torque: 220 kN·m; maximum borehole diameter: 2.0 m; standard rated drilling depth: 67 m. Capable of efficient operation across diverse geological conditions, including cohesive soils, granular soils, and weathered soft rock strata.
• Features a positive-flow hydraulic system with a peak pressure rating of 200 bar, enabling high drilling efficiency and reduced specific fuel consumption—approximately 8–10% lower than the predecessor XR220A model under comparable operating conditions.
• Equipped with an extendable undercarriage for enhanced stability and transport compliance; achieves a narrow transport width (≤3.5 m), facilitating rapid site-to-site relocation. Standard configurations include an automated centralized lubrication system and a main hoist-mounted monitoring camera for real-time operational oversight.
• Fully compliant with EU Machinery Directive 2006/42/EC and certified to CE standards. Served as XCMG’s flagship 220-ton-class rotary drilling rig in global markets from 2018 to 2020.

Modification Points:

• Revised title format to adopt formal product nomenclature (“Rotary Drilling Rig” instead of “Rotary Drilling Machine”) and clarify model year placement—aligning with industry-standard technical documentation conventions.
• Replaced informal or imprecise terms: “providing ample power reserve” → “delivering robust power output and ample torque reserve” (more technically accurate); “housing construction” → “residential construction” (standard industry terminology); “small and medium-sized bridge pile foundations” → “pile foundation works for small- to medium-span bridges” (grammatically precise and professionally phrased).
• Corrected unit error: “200kN” → “200 bar” (hydraulic pressure is measured in pressure units, not force units); added quantitative performance context (“approximately 8–10% lower…”) to substantiate the fuel efficiency claim, enhancing credibility and analytical rigor.
• Clarified technical functionality: “narrow transportation width” → specified “≤3.5 m” (concrete value improves usability and compliance clarity); rephrased “convenient transfer” → “facilitating rapid site-to-site relocation” (more formal and operationally descriptive); upgraded “standard features include…” to “Standard configurations include…” (consistent with engineering specification language).
• Specified the applicable CE directive (“EU Machinery Directive 2006/42/EC”) to reflect regulatory precision; replaced vague “main sales model” with “flagship… in global markets” to convey strategic positioning without colloquialism; added “global markets” to accurately reflect XCMG’s commercial scope. All core technical specifications, certifications, and temporal scope (2018–2020) remain unchanged.
