JC617 Compact Crawler DTH Drill Rig – 30m Depth, 90-100mm Holes, 2400Nm Torque for Confined Spaces

The rig adopts a reinforced feed and rotation system that ensures powerful penetration capacity. It delivers a maximum rotary torque of 2400 N·m and operates at a rotary speed suitable for deep, precise drilling. The drill string features φ64 mm × 3000 mm rods, optimized for both strength and adaptability in fragmented or abrasive formations.

Powered by a high-output diesel engine, JC617 is equipped with an efficient hydraulic system that controls feeding, lifting, rotation, and positioning functions through a centralized interface—enabling smooth operation and reduced manual effort. The integrated design enhances operational safety while improving energy efficiency across long drilling cycles.

The heavy-duty chassis and stable tramming structure allow the rig to maintain reliable mobility across complex terrain. Dust suppression, sealed electrical components, and a user-focused maintenance layout minimize downtime and enhance the machine’s durability in harsh outdoor environments. Whether used in mineral exploration or production drilling, JC617 delivers consistent results with lower operating cost and longer service life.
