Heavy-Duty Shock Absorber for Rock Drill Jumbos Engineered to mitigate excessive vibration in rock drill jumbos, this shock absorber protects critical components from dynamic loads during drilling operations. Its 304 stainless steel casing and NBR rubber core deliver consistent damping performance, even in harsh mining environments with dust, moisture, and temperature fluctuations .
Technical Specifications & Design
Core Components:
304 Stainless Steel Casing: Resists corrosion in underground and surface mining conditions, compliant with ASTM A240 standards for durability .
NBR Damping Core: 60 Shore A hardness rubber provides optimal energy absorption, reducing vibration transmission by 40% in drill arm pivot points .
M12 Threaded Mounts: Ensures secure attachment to structural frames, compatible with standard fasteners .
Performance Advantages
Vibration Reduction: 800N damping force at 0.5m/s velocity minimizes equipment wear, extending service intervals for hydraulic hoses and electrical components .
Environmental Resilience:
IP65 rating (IEC 60529) protects against dust ingress and low-pressure water jets .
Wide temperature range (-30°C to +80°C) adapts to extreme climate conditions .
Longevity: Passed 100,000-cycle fatigue testing per ISO 18737, ensuring reliable performance in high-frequency vibration scenarios .
Applications
Rock Drill Jumbos: Installed at drill arm pivot points and frame connections to dampen drilling-induced vibration.
Mining Equipment: Compatible with tunnel boring machines, hydraulic drills, and heavy-duty loaders.
