Heavy-Duty Cover Assembly for Hydraulic Rock Drills This cover assembly is engineered to protect internal components of hydraulic rock drills from dust, water, and impact damage in mining and construction environments. Constructed from carbon steel (S235JR) with a durable powder coating, it balances structural strength and corrosion resistance, ensuring long-term reliability in harsh operating conditions.
Key Features & Performance
Material & Durability:
S235JR carbon steel provides high tensile strength (360-510MPa) and rigidity, withstanding 10J impact forces from rock fragments and equipment handling .
80μm polyester powder coating (ISO 12944-5) offers 500-hour salt spray resistance (ASTM B117), preventing rust in damp underground mines .
Protective Design:
IP65 rating (IEC 60529) ensures complete protection against dust ingress and low-pressure water jets, safeguarding sensitive hydraulic and electrical components. The EPDM gasket creates a tight seal between the cover and drill housing, reducing maintenance intervals by 40% .
Compatibility & Installation:
Designed to fit standard hydraulic rock drill housings, with 8mm mounting holes machined to ISO 2768 medium tolerance for easy alignment. The lightweight design (4.2kg) simplifies manual installation without compromising durability .
Applications
Primary use in hydraulic rock drills for tunneling, quarrying, and mineral exploration.
Suitable for protecting gearboxes, hydraulic valves, and drive mechanisms in heavy-duty drilling equipment.
