1. Reaches 350 m Depth
A listed drilling depth of 350 m gives the JTRC-350 practical reach for deeper water well work, mineral exploration and geotechnical drilling without moving into a much larger rig class.
2. 105-400 mm Holes
The 105-400 mm drilling hole diameter range gives the rig broad coverage across different bore sizes. Support for 76 mm, 89 mm and 102 mm drill pipes adds more flexibility when matching tools to site requirements.
3. 260 kN Lift Force
A power head lifting capacity of 260 kN and propulsion force of 130 kN give the rig the push-pull performance needed for stable hard rock drilling and routine drill string handling in demanding field conditions.
4. RC Hammer Ready
The listed compressor matching range of 1.7-3.5 MPa and 17-42 m3/min, paired with a reverse circulation series DTH hammer setup, makes the machine ready for RC drilling configurations used in medium- and high-air-pressure work.
5. Fast Feed System
A 3.3 m feed stroke, 20 m/min fast lifting speed and 40 m/min fast feeding speed help reduce unproductive time during rod handling and support better working efficiency across daily drilling cycles.
