High-performance A25A hydraulic rock drill

1. Basic Concept
  • The A25A is a high-performance 25kW hydraulic rock drill, specially designed for surface open-pit drilling work. The letter "A" represents surface and open-air operation scenarios.
  • It is a core supporting device for hydraulic drilling rigs, adopting advanced hydraulic drive technology to achieve high-frequency and high-power rock breaking.
  • This model is optimized for long-duration, high-intensity drilling, perfectly adapting to various complex open-pit mining and construction environments.
2. Key Features
  • It adopts high-strength alloy steel body with integral heat treatment, featuring high rigidity, impact resistance and deformation resistance.
  • Compatible with T45 and T51 standard shank adapters, supporting multiple drilling diameters to meet diverse construction needs.
  • Equipped with an efficient vibration buffer system to reduce equipment vibration and protect internal precision components.
  • Built-in stable aerosol lubrication and enhanced dustproof structure, adapting to dusty and harsh outdoor working conditions.
3. Application Scenarios
  • Widely used in open-pit mines and quarries for blast hole drilling, rock excavation and grade control drilling.
  • Applicable to highway, railway and municipal engineering for foundation drilling and rock reinforcement construction.
  • Suitable for medium and ultra-hard rock drilling in geotechnical exploration and outdoor engineering projects.
4. Main Advantages
  • 25kW high power output provides strong impact force, effectively improving drilling speed and overall construction efficiency.
  • Excellent wear resistance and environmental adaptability greatly reduce equipment failure rate in harsh open-air conditions.
  • Precise hydraulic control ensures low drilling deviation and improves drilling forming accuracy.
  • It has a simple and compact structure, convenient installation and maintenance, effectively lowering long-term operating costs.
