PRODUCT DESCRIPTION
JC618GF supports a wide hole diameter range from φ90 to φ400 mm, making it highly versatile across unconsolidated layers and mixed formations. With a maximum rotary torque of 8000 N·m and adjustable rotary speed up to 80 rpm, it delivers stable torque output for oversized hole drilling while maintaining control and precision.
The feed system uses a motor-driven mechanism with a 3300 mm feed stroke and 900 mm extension. It provides 18 kN of feeding force and 20 kN 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 92 kW, 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 1.0–2.4 MPa pressure and 15–50 m³/min air volume, ensuring compatibility with a wide range of pneumatic setups.
The whole machine weighs only 5.2 tons, with a compact footprint of 6400 × 2200 × 2550 mm for easy transport. A tramming speed of 0–2 km/h, 25° climbing ability, and 380 mm 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.
