Product Description： The YGRC-500 is a deep-hole model within the YGRC series of reverse-circulation exploration drill rigs. It features a maximum drilling depth of 500 meters and a borehole diameter range of 140–400 mm, making it suitable for rock with a hardness rating (F) of 6–20. Equipped with a six-cylinder Cummins diesel engine, the unit delivers 132 kW of power, a rotational torque of 8,500–12,000 N·m, and a power head lifting capacity of 300 kN (approximately 30 tonnes). This configuration ensures ample power and lifting reserve, even when operating in conditions involving deep holes, hard rock, or long drill strings.
Product Features： 1) Rotary Torque: 8500–12000 N·m; ensures stable rotation during deep-hole drilling and minimizes the risk of drill bit jamming. 2) Lifting Capacity: 300 kN for the power head; 20 kN for the winch. 3) Hole Diameter and Drilling Tools: Hole diameter 140–400 mm; drill rods available in diameters of Φ89, Φ102, and Φ114 mm, with lengths of 1.5 m, 2 m, 3 m, or 6 m. 4) Operational Efficiency: Single-pass feed length of 3.3 m / 6.6 m. 5) Chassis and Support: Hydraulic crawler-type undercarriage with steel tracks; travel speed of 2.5 km/h; gradeability of 25°; equipped with 4 high-reach hydraulic outriggers.
Application Scenarios： Used for deep-seated mineral exploration and grade-control sampling, deep geological reconnaissance and anomaly verification, deep-hole engineering geological investigation (for highways, railways, bridges, tunnels, and dams), deep-hole hydrogeological and water-well investigation, placer deposit exploration, investigation of mined-out areas and tailings, as well as drilling for scientific research and educational purposes.
