Product Description

Product Description                     
Features

This crawler-mounted single-boom face drilling rig is engineered for blast hole drilling in non-coal mines, railway tunnels, water diversion projects, and defense drifts, adapting to cross-sections from 2.5×2.5 m to 4×4 m. Its compact frame and crawler chassis deliver exceptional mobility and gradeability, making it ideal for slope operations, short-distance transfers, and sublevel mining.

Powered by a diesel-electric dual-power system compliant with China Stage III emission standards, the rig features a parallel drill boom with 360° rotation and automatic parallel adjustment. This enables precise wall hole and cut hole drilling with a single positioning. The high-power rock drifter, equipped with dual-damping technology, achieves a penetration rate of 0.8-2 m/min even in F17 hard rock, extending tool lifespan and reducing maintenance costs.

To handle diverse working conditions, it integrates automatic anti-jamming and rod retraction functions, alongside a hydraulic circuit braking system. Multiple configurations are available-standard, steep-slope, and extended telescopic boom models-to adapt to different operational needs. A FOPS (Falling Object Protective Structure) and ROPS (Roll Over Protective Structure) certified canopy provides robust protection for operators.

Key Features & Benefits

• Crawler Mobility & Dual-Power System
  The crawler chassis ensures excellent traction on slopes and rough terrain, while the diesel-electric dual-power system delivers reliable performance and meets strict emission standards.
• Precision Drilling Efficiency
  The parallel boom with 360° rotation and automatic parallel adjustment enables full-face drilling in one positioning, with the dual-damping rock drifter ensuring fast penetration and tool durability.
• Versatile Configurations
  Available in standard, steep-slope, and extended boom models to suit slope operations, narrow drifts, and large cross-section requirements.
• Intelligent Safety Protection
  Automatic anti-jamming, hydraulic braking, and FOPS/ROPS certified canopy ensure operator safety and equipment reliability in harsh underground environments.
