Versatile Pneumatic Diesel Power DTH And Auger Drill Surface Compact Drilling Rig

>> Products Description

>> Designed for flexible deployment across diverse drilling environments, JC618GF is a compact yet powerful down-the-hole drilling rig tailored for shallow large-diameter hole applications. Its optimized structure and high adaptability make it ideal for municipal  construction, geothermal drilling, small-scale quarries, and pipeline foundation projects. JC618GF supports a wide hole diameter range from φ90 to φ400mm, making it highly versatile across unconsolidated layers and mixed formations. With a maximum rotary torque of 8000N·m and adjustable rotary speed up to 80rpm, it delivers stable torque output for oversized hole drilling while maintaining control and precision. The feed system uses a motor-driven mechanism with a 3300mm feed stroke and 900mm extension. It 
provides 18kN of feeding force and 20kN of lifting force, enabling smooth rod advancement and retraction even under unstable ground conditions. The rig's core motion components are configured for reliable performance with minimal mechanical complexity. Powered by a YUNNEI YN48GBZ diesel engine rated at 92kW, JC618GF delivers dependable output while remaining fuel-efficient, supported by a 100-liter onboard fuel tank. It matches seamlessly with external air compressor systems requiring 1.0-2.4MPa pressure and 15-50m³/min air volume, ensuring compatibility with a wide range of pneumatic setups.
Hole range: 90-400mm
Hole depth: 10m 

The whole machine weighs only 5.2 tons, with a compact footprint of 6400×2200×2550mm for easy transport. A tramming speed of 0-2km/h, 25° climbing ability, and 380mm ground clearance give JC618GF strong off-road capability and maneuverability in constrained or rugged job sites. With a design focus on operational efficiency, durability, and large-bore drilling flexibility.
