Description
The SMC-DTH-CRN180 is a state-of-the-art full hydraulic core drilling rig engineered for high-performance applications in mining exploration, geotechnical engineering, construction, and deep geological surveys. Designed to deliver superior depth capacity and operational flexibility, this rig features a robust 178 kW Cummins engine, cutting-edge hydraulics, and intelligent control systems.
Built with a closed-circuit dual-motor spindle system, the CRN180 offers high torque output (up to 6400 N·m) and stepless speed regulation for a wide range of core drilling tasks. It integrates a two-speed mechanical gearbox and hydraulic gearbox to ensure smooth transitions and control in varying formations. The mast system provides a long feeding stroke of 3700 mm and a full angle range of 0° to 90°, making it suitable for both vertical and angled boreholes.
With a maximum drilling depth of up to 2200 m (BQ rods), high-capacity hoisting systems, and load-sensitive hydraulics, this crawler-mounted rig offers unmatched mobility, stability, and productivity. Advanced features like hydraulic clamps, digital monitoring, and dual operation panels make the SMC-DTH-CRN180 an elite choice for deep core drilling operations in harsh environments.
