JTRC-350 RC Drill Rig

350m Deep-Hole Capacity | 105-400mm Diameter | 129kW Weichai Power | 260kN Lifting Force

Product Overview

The JTRC-350 is a high-performance reverse circulation (RC) drill rig purpose-built for 350-meter deep-hole operations. Ideal for mineral exploration, hard rock water wells, and geotechnical engineering, it combines a high-torque 129kW Weichai engine with versatile air-pressure compatibility. Its fast-feed system and robust pullback capacity ensure maximum efficiency in demanding, mid-depth drilling projects.

Key Features

350m Deep-Hole Reach: Provides practical, high-reach drilling capacity for mineral sampling and exploration beyond standard mid-range rig limits.
RC-Ready Power: Configured for medium/high-pressure DTH hammer reverse circulation, perfectly matched with 1.7-3.5 MPa air compressors.
Exceptional Lifting Force: 260kN pullback force and 130kN propulsion force provide the stable handling required for deep, challenging hard-rock formations.
High-Torque Performance: 8,000-12,000 N.m torque output ensures consistent rotary power in high-density ground conditions.
Cycle Efficiency: 3.3m feed stroke coupled with high-speed lifting (20 m/min) and feeding (40 m/min) drastically reduces non-drilling cycle times.
