    • Constructed from quenched alloy steel (42CrMo4) with a two-layer epoxy-polyurethane coating, resistant to acidic mine water (pH 4–6) and abrasive dust.

COP 1840+ Series

  • Application: Open-pit quarrying, large-scale mining
  • Technical Specifications:
    • Hole Diameter: 76–102 mm
    • Rated Power: 19 kW
    • Suitable Conditions: Hard rock (compressive strength 120–200 MPa), supports deep-hole drilling (max depth 28 m).
  • Functional Match:
    • Integrated NBR O-ring seals (ISO 3601-1 compliant) maintain sealing performance in extreme temperatures (-20°C to +120°C).
    • Precision-machined holes with ISO 2768-1 fine-class tolerances (±0.1 mm) ensure accurate alignment with hydraulic pumps and valves.

Compatible Drill Rig Models

Boomer L2C

  • Type: Two-boom underground 掘进凿岩台车 (underground development jumbo)
  • Application: Medium-sized drifts (height ≤6 m), tunnel blast hole drilling
  • Technical Parameters:
    • Maximum Coverage Area: 48 m²
    • Feed Beam Length: 4.9 m
    • Compatible Drill Rods: R32E, R38, T38 types.
  • Adaptation Logic:
    • The connecting plate is secured to the Boomer L2C’s hydraulic power unit (HPU) with 4 M12 bolts (torque 40–45 N·m), transmitting hydraulic oil flow (max 150 L/min).
    • Designed for 10,000 hours of continuous operation under heavy-duty conditions.
Key Features
  • High-Strength Construction
    Manufactured from quenched and tempered alloy steel (e.g., EN 10083-3 42CrMo4) with a yield strength of 850 MPa, the plate resists deformation under heavy loads (up to 50 kN) common in high-impact 凿岩作业.
  • Precision Machining
    All mounting holes are drilled to ISO 2768-1 fine-class tolerances (±0.1 mm), ensuring a secure fit with hydraulic pumps, valves, and cylinders, while minimizing vibration-induced stress on connected components.
  • Leak-Proof Sealing Design
    A grooved interface with pre-installed NBR O-rings (compatible with ISO 3601-1 standards) creates an airtight seal, preventing hydraulic fluid leakage even at maximum system pressure (35 MPa) and extreme temperatures (-20°C to +120°C).
  • Corrosion Resistance
    The surface is coated with a two-layer epoxy-polyurethane finish, providing protection against moisture, acidic mine water (pH 4–6), and abrasive dust, ideal for underground and wet drilling environments.
Applications
  • Underground Mining: Suitable for jumbo drills, raise boring machines, and longhole rigs requiring stable hydraulic connections in narrow drifts (minimum width 2.7 meters) or deep tunnels (3.44–5.88 meters in diameter).
  • Surface Drilling: Ideal for crawler-mounted drills in open-pit quarries, supporting medium-to-deep hole drilling (89–165 mm diameter) by maintaining hydraulic system integrity under high-frequency vibrations.
  • Construction & Tunneling: Compatible with hydraulic drills used in tunnel boring, foundation drilling, and pile driving, ensuring reliable performance in confined spaces and high-pressure fluid systems.
Benefits for Industrial Operations
  • System Stability: Precise hole alignment reduces hydraulic component misalignment, extending the lifespan of pumps and hoses by up to 25%.
  • Leak Prevention: Reliable sealing design minimizes fluid loss, avoiding costly downtime for maintenance and environmental cleanup.
  • Cost Efficiency: Durable materials and corrosion resistance reduce replacement frequency, offering a low total cost of ownership for fleets operating in harsh conditions.
Installation & Maintenance
  • Installation:
    1. Clean the mounting surface and ensure no debris is present.
    2. Tighten bolts to 40–45 N·m using a torque wrench (follow equipment manual for specific requirements).
  • Maintenance:
    • Inspect seals for wear or damage during routine checks; replace O-rings every 1,000 operating hours in harsh environments.
    • Clean and reapply anti-corrosion grease to exposed metal surfaces annually.
  • Storage: Store in a dry, dust-free environment to prevent coating damage and seal degradation.
