JC843 High-Efficiency DTH Drill Rig Rapid-Cycle Drilling Solution for Time-Sensitive Projects

The rig’s rotation system features an Eaton 2K series motor delivering up to 2200 N·m torque and variable speeds from 0 to 100 rpm, providing controlled drilling dynamics. Its feed system utilizes a motor-driven chain mechanism that ensures smooth, reliable feed motion with a 3400 mm stroke and 1100 mm extension, capable of applying a maximum feeding force of 12 kN and a feed speed up to 1 m/s.

Powered by a high-output 162 kW Yuchai diesel engine, JC843 integrates a two-stage compression air system delivering 15 m³/min at 1.8 MPa working pressure, optimizing pneumatic energy for down-the-hole hammer efficiency. The rig’s high-strength steel feed beam and durable frame construction enhance operational stability and longevity under heavy workloads.

Weighing 9.5 tons and measuring 8400 × 2300 × 2400 mm, the rig balances substantial power with manageable transport size. With tramming speeds of 3 km/h (fast) and 1.5 km/h (slow), JC843 adapts well to site mobility demands. The 12-core dry-type dust collector improves onsite air quality and maintenance convenience.

Incorporating QIANGTIAN control valves and imported IP56-rated electrical components, JC843 guarantees precise hydraulic control and robust environmental protection. This rig is a reliable choice for contractors seeking durable, high-performance drilling equipment with enhanced operator safety and low maintenance requirements.
