JC712 Export Extended Reach Drilling System DTH Drill Rig for Deep Bore Applications

The rig delivers a powerful maximum rotary torque of 2500 N·m at variable speeds up to 140 rpm, ensuring efficient rock penetration and stable hole formation. The robust hydraulic oil cylinder feed system offers a 3340 mm stroke and 900 mm extension with 15 kN feeding force and 25 kN lifting capacity, enabling smooth and controlled rod handling during drilling.

Powered by a reliable Yuchai YC4A100-T20 diesel engine rated at 70 kW, JC712 balances power and fuel efficiency supported by a 70-liter fuel tank. Its pneumatic system requires an air compressor capable of supplying 10–18 m³/min at 0.7–1.8 MPa, suitable for a variety of air supply conditions.

With a total weight of 5.3 tons and compact transport dimensions of 5550 × 2290 × 2600 mm, JC712 offers excellent mobility and site accessibility. Its 35° climbing capacity and 450 mm ground clearance enable operation on rugged terrain, while the optional winch adds versatility for demanding environments.

The rig features a 12-core dry-type dust collection system, enhancing environmental compliance and operator safety by minimizing airborne particulates. This, combined with the machine’s sturdy build and user-friendly control interface, makes JC712 a dependable choice for efficient, clean, and flexible drilling operations.
