The JTRC-350 features a 129 kW Weichai diesel engine rated at 2,200 rpm and a hydraulic rotary drilling system delivering 8,000–12,000 N·m of torque. Its 260 kN power head lifting force, 130 kN feed force and 3.3 m feed stroke support drill-string handling and drilling operations in demanding rock formations.
The rig is specified for matching air compressor systems operating at 1.7–3.5 MPa with 17–42 m³/min air flow. Drill pipe diameter options include 76 mm, 89 mm and 102 mm. For mineral exploration RC sampling, compatible dual-wall drill pipes, reverse circulation hammers, compressors, cyclone separators and sample collection equipment should be selected according to the drilling diameter, geology and required sample recovery method.

350 m Deep-Hole Drilling Capability: Supports reverse circulation drilling across a 105–400 mm hole diameter range for mineral exploration, geological investigation and compatible hard rock drilling projects.
High Rotary Torque & Pullback Force: Delivers 8,000–12,000 N·m rotary torque, 260 kN lifting force and 130 kN feed force for demanding drilling and drill-string handling operations.
Efficient Feed System & Compressor Compatibility: A 3.3 m feed stroke, 20 m/min fast lifting speed and 40 m/min fast feeding speed support drill-string handling, while the specified compressor matching range allows project-specific air supply selection.
Maximum drilling depth and actual drilling performance depend on geology, hole diameter, drill string, bit or hammer selection, air pressure, air flow and operating conditions. Compressor specifications indicate matching requirements, not standard equipment supplied with the rig. Dual-wall RC drill pipes, RC hammers, cyclone separators, sample collection systems and all optional equipment must be confirmed in the final quotation and supply list.
