Heavy-Duty Stabilizer for Rock Drill Jumbos Engineered to ensure precise drill bit alignment in rock drill jumbos, this stabilizer minimizes deflection during drilling operations. Its 4140 alloy steel construction with tungsten carbide coating delivers exceptional durability, even in abrasive rock formations common in mining and tunneling .
Technical Specifications & Design
Core Performance Traits:
High-Precision Guiding: ±0.1mm accuracy reduces drill bit deviation by 40%, ensuring consistent hole placement and reducing material waste in tunneling projects .
Durable Construction: 900MPa tensile strength and 50HRC surface hardness (induction-hardened) resist wear, while the tungsten carbide coating extends service life by 50% compared to uncoated stabilizers .
Shock Absorption: Integrated rubber rings dampen vibration from impact drilling, protecting both the stabilizer and drill bit from premature failure .
Performance Advantages
Environmental Resilience:
Operates reliably from -30°C (cold underground mines) to +150°C (high-friction drilling), maintaining guiding precision across temperature extremes .
1000-hour salt spray resistance (ASTM B117) protects against corrosion in wet mining environments.
Versatility:
Compatible with 30-50mm diameter drill bits, adapting to various rock types and drilling requirements.
50kN load capacity supports heavy-duty drilling in hard rock formations (e.g., granite, basalt) .
Applications
Rock Drill Jumbos: Essential for horizontal/vertical drilling in tunneling, quarrying, and mineral exploration.
Mining Equipment: Used in blast hole drills and exploration rigs requiring precise hole positioning.
Construction Machinery: Suitable for foundation drilling and rock excavation projects.
