1. Ultra-deep hole drilling capability: one machine for all operating conditions Capable of reaching a maximum drilling depth of 800m with hole diameters ranging from 105–400mm, this rig is suitable for rock with a hardness rating (F-scale) of 6–20. It handles everything from shallow-hole sampling to ultra-deep hard-rock exploration with ease. 2. Cummins six-cylinder engine: powerful output for demanding tasks Equipped with a six-cylinder Cummins diesel engine delivering 194kW of power, the rig provides a consistent and robust reserve of energy—essential for ultra-deep drilling, hard-rock formations, and operations requiring long drill strings. 3. High-torque rotation: effortless drilling in hard rock With a rotational torque of up to 10,000–20,000 N·m, the rig maintains efficient rock-breaking performance even in high-strength, hard-rock strata, simultaneously boosting drilling speed and hole quality.

Product Description： The YGRC-800 reverse circulation drilling equipment is the flagship model in the YGRC series of reverse-circulation exploration drill rigs. It offers a maximum drilling depth of 800 meters and a hole diameter range of 105–400 mm, making it suitable for rock formations with a hardness rating (F) of 6–20. It is designed to meet a full spectrum of exploration requirements, ranging from shallow holes to ultra-deep drilling in hard rock. Powered by a six-cylinder Cummins diesel engine, the rig delivers 194 kW of power, a rotational torque of 10,000–20,000 N·m, a power head lifting capacity of 47 tonnes, and a winch lifting capacity of 2.5 tonnes—providing ample power and lifting margin for ultra-deep, hard-rock, and long-drill-string operations. It comes standard with 3m/6m drill rods and features a 6m single-pass feed stroke, which significantly reduces the frequency of rod handling (adding/removing rods) and effectively enhances operational efficiency.
