Heavy-Duty Protector for Hydraulic Rock Drills This protector is engineered to shield critical components of hydraulic rock drills from abrasion, impact, and debris in mining environments. Its robust construction ensures extended service life of drill shanks and associated parts, reducing maintenance downtime and operational costs.
Technical Specifications & Design
Material & Durability:
Constructed from high-chrome cast iron (ASTM A532 Class II) with 20% chromium content, forming a wear-resistant carbide matrix. This material achieves 80,000 cycles of reliable performance under standard drilling conditions, outperforming conventional steel protectors by 200% .
The 4mm thick wear layer (HRC55-60) provides exceptional resistance to gouging and wear, while the ductile substrate absorbs impact loads (15J Charpy test), preventing cracking during heavy-duty operation .
Precision & Compatibility:
±0.1mm dimensional tolerance (ISO 286-1) ensures a precise fit with R32 drill shanks (ISO 10424-1), minimizing vibration-induced wear. The integral keyway slot (ISO 13531) facilitates quick alignment and installation, reducing assembly time .
Shot-peened surface (Ra 3.2μm) reduces stress concentrations, enhancing fatigue resistance in high-vibration environments typical of rock drilling operations .
Environmental Adaptability:
Operates reliably across a wide temperature range (-30°C to +110°C), maintaining hardness and structural integrity in both cold underground mines and high-friction drilling zones. Its corrosion-resistant properties prevent rust-related degradation in damp mining conditions .
Applications
Hydraulic Rock Drills: Protects shanks and connecting components in horizontal, vertical, and angled drilling operations.
Mining Equipment: Compatible with tunnel boring machines, quarry drills, and mineral exploration rigs utilizing R32 drill systems.
Construction Machinery: Suitable for rock excavation and foundation drilling equipment requiring robust component protection.
